Feasibility Study for Solid Waste Master Plan
Fez, Morocco

Services Provided:

• Preliminary Investigations
• Evaluation of Alternatives
• Conceptual & Preliminary Design of Recommended Alternatives
• Economic Analyses
• Environmental and Health Impact Assessments
• Development of Implementation Plans
• Report Preparation

Before EII Involvement The City of Wilaya of Fez (population 800,000)

lacked a comprehensive waste management plan,

which in turn had a direct negative impact on the

city. At the beginning of the study, the City spent

approximately $150,000 annually in managing

solid waste and yet municipal solid waste was not

collected frequently causing accumulation in

ditches around the city. This situation threatened

the population’s health, created the potential for

water contamination and began to undermine the

growth of tourism. To address this problem, the

United States Trade and Development Agency and the President of Wilaya of Fez selected Edgeboro

International Inc. to conduct a Feasibility Study to determine alternative methods of waste

management.

Working with Sadat Associates, an Environmental Engineering firm, Edgeboro conducted a study of
the present situation, current collection practices and the structure of waste management in the city.
The results of this initial evaluation were used to prepare a solid waste master plan.

Landfill Operation and Closure
Fez, Morocco

Edgeboro International Inc. was awarded the on going contract to close an existing 20 year old landfill
for the City of Fez.

The existing landfill required major reconstruction to
improve the working conditions of the facility. These
improvements helped to create a safe environment for
personnel and to ensure the proper use of equipment. Years
of improper operation left the landfill with numerous open
methane fires throughout the site and clouds of hazardous
smoke that covered the site eventually traveling to the
nearby town. Waste was piled 40 to 60 feet high, which
created unstable edges around the perimeter of the landfill.
Lack of daily covering activities and no leachate
collection/disposal system, ultimately resulted in exposed
rotting waste.

Edgeboro International Inc. regraded the facility, extinguished the methane fires and operated the site as
a sanitary landfill. A surface water diversion channel was constructed to reroute an existing stream away
from the landfill, thereby eliminating the contamination with the leachate from the landfill. The final grade
design will allow for the proper capping of the facility when it is time to be closed. A clay cap will be
installed to close and seal the landfill to prevent further groundwater contamination.

Landfill Construction and Operation
Fez, Morocco

Edgeboro International Inc. was awarded the on going
contract for the construction and operation of a new,
state of the art landfill for the City of Fez. This new
landfill for the City of Fez (population 800,000) was
designed to supply the city with the necessary
disposal capacity for the next twenty years.
The landfill consists of a natural clay impermeable liner,
leachate collection system, methane collection system and
enclosed flare, onsite LFG to energy generation, diversion
swales, electronic scale house, access roads, equipment
shop and office. The landfill operation utilizes the latest in Caterpillar landfill equipment and
environmental operation standards.

Note:
• The Fez Landfill is the first state of the art controlled landfill for Morocco and North Africa
• The Fez Landfill installed the first Landfill Gas to Energy Plant in Morocco and North Africa

Casablanca Landfill
Casablanca, Morocco

The City of Casablanca selected Edgeboro International Inc.’s local company ECOMED for the design,
funding, implementation and operation of the landfill for the city. This on going contract
includes the remediation and closure of the existing landfill for a contractual period of 18 years.
The Casablanca Landfill is Morocco’s largest landfill accepting approximately 1,200,000 tons per
year and operates 24 hours/7 days a week.

The major remediation of the existing site, which is
more than 300 acres, is a very complex and extensive
project. The landfill was completely uncontrolled with
open dumping taking place for the past 20 years. The
site contained impassable access roads, numerous
landfill fires, extensive leachate outbreaks and plumes
of noxious smoke that were constantly blowing off site
into nearby communities. These dangerous plumes
frequently caused adjacent highway auto accidents and
road closures. Edgeboro International Inc. and partner
GESI along with its local company
ECOMED, developed a closure plan and commenced
operations to correct and install the necessary controls
for the site.

The new landfill consists of 6 new composite lined cells used to deposit new waste. The new landfill now
includes all the necessary infrastructures to properly control and manage stormwater, leachate and biogas
produced at the facility.

Emergency Stabilization Extraction System
Bogota, Columbia

The Doña Juana Landfill is a privately operated landfill that handles over 4,500 tons of municipal solid
waste daily. That means this site is solely responsible for 90% of the waste generated by the City of Bogotá
(population of 6 million). A recently failed section of the landfill slid down the side of the mountain
carrying over 800,000 cubic meters of waste coming to a rest at the valley floor ultimately blocking a
small river. This is the largest reported mass movement of solid waste in history.

Edgeboro International Inc. was approached to design, manage and coordinate the construction of an
Emergency Stabilization Extraction System. The system was designed to reduce the pore pressure within
the adjacent portion of the landfill to help stabilize the section that failed. Previous efforts by other firms
proved unsuccessful after experiencing several setbacks and failures. Prior attempts to extract leachate
proved difficult due to the intense methane gasification of the leachate, which caused the leachate to foam
and the electric pumps to aerate. Other attempts to stabilize the landfill also proved ineffective due to the
high leachate levels found in the landfill. This high level of leachate resulted in the gas being inaccessible
as well as incompatible with conventional methane systems. These were the two key faults the landfill
experienced, which led to incredible pore pressure thus causing a major portion of the landfill to fail.

Edgeboro was retained by DAMA to stabilize the landfill and approached the situation with a two-step
method. First, a series of methane extraction wells were installed. Second, constructed a two-part system
that sealed off and restricted gas flow to cause positive pressure. This system included pumping leachate
levels down with specially designed pneumatic pumps and then utilizing a secondary system to control
the methane gas with special wellheads. The entire field was then placed under a vacuum enabling the
flaring of the methane gas. The extraction wells were then piped together with HDPE leachate discharge
lines, methane extraction lines and pneumatic air lines to collect, contain and power the entire well field.
The result was the significant reduction in pore pressure and stabilization of the adjacent portion of the
landfill.

Note: Due to the severity of the problem,
Edgeboro was requested to mobilize at an
accelerated pace. Edgeboro preassembled the
necessary equipment and construction
materials in the United States, which were then
packaged and shipped in containers for
assembly in the city of Bogotá. Edgeboro then
began construction of the methane wells by
hiring and training local manpower and
materials.

Methane Gas Collection System Kingsland Landfill
Lyndhurst, NJ

Edgeboro International Inc. was awarded the contract to
install a new methane collection system for the Kingsland
Landfill in Lyndhurst, New Jersey. The new collection
system was designed to accommodate the new proposed 18-
hole golf course that was part of the master plan to redevelop
the Meadowlands.

The installation of the methane gas collection system
included more than 40,000 lf of collection headers, laterals
and condensate lines needed to tie together 80 new methane
collection wells. The entire system had to be constructed
without disrupting the existing methane gas collection
system and power plant.

Bentonite Clay Cut-off Wall
Bayonne NJ

New Jersey Phase One for procurement of dredge capping material.

The OENJ Cherokee Corporation (OENJ) Bayonne site
consists of former industrial land south of the Military
Ocean Terminal on the Constable Hook in the City of
Bayonne, New Jersey. The property is bounded on the
North and East by the Upper New York Bay and on the
South by several chemical manufacturing and industrial
facilities. The site was part of the New York Bay until
the early 1900s, when the Constable Hook area was
filled with various wastes and fill material during the
period from 1910 to 1983.

The project included a 38 acre former municipal landfill and a 97 acre industrial fill site formerly owned
by PSE&G. OENJ eventually properly capped and closed the former landfill and remediated and capped
the former PSE&G site using approximately 4.5 million cubic yards of amended dredged material from
the New York Harbor along with other recyclable materials. Once the site was remediated and capped, it
was developed into an 18-hole golf course called the Bayonne Golf Club. Additional amenities include a
club house, wetlands refuge area, perimeter public waterfront walkway, ferry terminal and heliport.

There were several pertinent environmental issues to address in order to properly remediate the site. Phase
One consisted of constructing the Bentonite Clay Slurry Wall necessary to hydrologically isolate the site
and prevent further contamination to the New York Bay and surrounding area. The containment of the site
was required by the New Jersey Department of Environmental Protection (NJDEP) before any further
environmental improvement and procurement of dredge material necessary to cap the site could be
initiated.

The 300,000 sf continuous Bentonite Clay Slurry Wall extends 14,000 lf to a maximum depth of 47 feet,
which keys into an underlying geological impermeable layer. The wall prevents the lateral movement of
groundwater both on and off the site. By preventing the migration of groundwater, the leachate collection
and treatment systems within the site will work more efficiently.

NERC Middlesex Solar One
East Brunswick, NJ

The NERC Middlesex Solar One is a solar array consisting of approximately 9,000 thin film solar panels
situated on 26 acres of the closed and capped Edgeboro Landfill. This converted a previously unusable
area of the landfill into a major green energy generating facility.

The design and construction of this particular solar
array was unique and quite challenging compared to a
typical Greenfield solar. This solar array had to meet
the needs required of a Title 5 landfill, develop a
proprietary racking technology to work on the side
slopes of the landfill as well as be cost effective. Key
design components of this solar project were meeting
the needs of the landfill regulatory requirements,
keeping in mind the existing environments
infrastructure and ensuring the continued ability of
simple maintenance.

Newkirk Electric was selected as the EPC contractor during construction and subcontracted
Edgeboro International Inc. to perform the environmental, site work and the installation of the
rack system, anchors and approximately 9,000 ENN North America 500 watt thin film solar panels.
The ENN North America 500 watt thin film solar panels are the largest panels installed in the United
States. The panels now produce 3.9 MW (AC) of electrical energy which is fed into the PJM grid to
power area homes and businesses.

Landfill Gas Vacuum Test Project
Milpillas, Mexico

Environ Engineering contracted Edgeboro International Inc. to mobilize necessary manpower and
equipment to perform an investigative vacuum gas test on the Milpillas Landfill. US test equipment was
shipped to Mexico and a local contractor installed methane gas wells in locations determined by Environ.
Technicians assembled the custom designed portable flare and performed a battery of tests to collect well
data over a period of three weeks. The data collected was instrumental in determining if the landfill was a
viable site for the planned LFG to Energy Plant. It was also instrumental in determining the design of the
collection system and ultimate size of the power plant.

Cinnamon Bay LLC Landfill Gas to Energy Plant
East Brunswick, NJ

The Cinnamon Bay LLC Landfill Gas to Energy Plant
is a new, highly efficient Class 1 Renewable Energy
electrical generating facility. The plant recovers
energy from landfill gases (LFG), which would
otherwise be flared or vented. Situated in East
Brunswick NJ, the now closed and capped Edgeboro
Landfill currently produces more than 3,000 cubic feet
per minute (CFM) of 506 BTU/cu ft gas continuously.
Rather than flaring these gases, Cinnamon Bay LLC
installed a highly efficient and reliable 9.6 MW power
plant consisting of six Caterpillar 3520 LFG
reciprocating engines at 1,600 kW each. Additional considerations and technology were incorporated with

the heightened requirements of the air permit and the
plant being located in a non-attainment area. Edgeboro
International Inc. was the general contractor for the
project and coordinated all phases of the construction of
the plant and plant startup. The addition of pollution
control Oxidation Catalysts and a state of the art LFG fuel
treatment system, make this system one of the most
advanced LFG to power systems in the nation. The
energy and capacity produced are sold directly to the PJM
wholesale market.

Bayonne Golf Club Project
Bayonne, NJ

Remedial Construction activities performed at the Bayonne Golf Course:

• Bentonite Clay Slurry Wall
• Leachate Collection System
• Methane Collection System
• Methane Gas Pump Test and Flare Rental
• Methane Gas Flame Installation
• Leachate and Gas Collection System Maintenance and Operation
• Maintenance and Operation

Leachate Collection System
Bayonne, NJ

Edgeboro International Inc. was retained to construct a
leachate collection system utilizing a Biopolymer
trenching methodology and a pneumatic pumping
system for OENJ Cherokee at the Bayonne Redevelop-
ment Site in Bayonne New Jersey.

Edgeboro redesigned the entire 13,000 lineal feet of
leachate collection lines and pump stations
incorporating the Biopolymer trenching methodology
along with a pneumatic pumping system in order to
minimize potential problems inherent in the original
design. Edgeboro was responsible for the following:

• Stability of the existing cut-off wall during construction of the leachate collection system
• The need to dewater open trenches in order to install pipes
• Excessive volume of excavation and the need to construct work platforms
• Minimal slope of the gravity collection lines that would be future maintenance problems
• The ability of the containment system to provide an inward hydraulic gradient at the

cut-off wall (i.e. leachate levels inside the cut-off wall lower than groundwater
elevations outside the cut-off wall)

The construction of the leachate collection system using conventional construction methods would have
been financially, technically and environmentally impossible due to the identified design flaws. Edgeboro
proposed an alternative solution, which solved the client’s problems as well as saved the client a
significant amount of time and money.

Biopolymer Deep Trenching with a Pneumatic Pumping System

A Biopolymer slurry was used to support the walls of the 25’ deep trenches where the perforated HDPE
pipe was installed to a specified grade before the stone aggregate was installed. A pneumatic pumping
system was incorporated into the collection network in order to complete the leachate collection design.

These particular construction methods also minimized the nuisance of decomposed waste odors, which
can emanate from open trenches in landfills. Additionally, since the pipes were laid at the bottom of the
excavation by the integrated construction equipment, the workers’ exposure to waste, leachate and landfill
gas was reduced. Thus health and safety was less of an issue during pipe installation.

Gas Extraction System

The installation of a gas recovery system which includes 24 vertical extraction wells, over 26,000 lf of
low flow gas collection piping systems, more than 10,000 ft of collection laterals and headers, pneumatic
pump installation, flare installation and a gas system balancing and testing.

6-Mile Methane Pipeline Project
Trumball, Connecticut

The Middlesex County Utilities Authority
(MCUA) approved a plan for a state-of-the-art
system that will utilize the methane gas produced
from decomposing solid waste in the Middlesex
County Landfill to generate both electrical power
and significant cost savings for the MCUA. The
project includes the construction of a com-
prehensive network of pipelines through which the
methane gas will be collected from three area
landfills and transported to an electrical power
generator at the MCUA’s Sayreville headquarters.

Edgeboro has operated the landfill gas collection and control systems of the following landfills: Edgeboro
Landfill, Middlesex Landfill, Edison Landfill and ILR Landfill from 1947 to 2005.

Edgeboro was retained to install six miles of pipeline through various elements, including solid waste,
soil, hazardous waste sites, wetlands, tidal areas and two river crossings. A 16-inch methane gas main was
installed to interconnect NERC’s three landfills to supply fuel to a newly constructed 18-megawatt power
plant. Construction involved trenching through the above elements at depths of 5-10 feet where SDR 32.5
16-inch pipe was laid within the specifications and requirements of the owner.

Methane Extraction System

Edgeboro International Inc. was retained by the NERC
Middlesex Gas Company to construct three methane
extraction systems at the Edison, ILR and Middlesex
County Landfills.

Due to a distinct differentiation among the three sites,
each facility was evaluated individually taking into
account the age of the facility, the type of waste
collected, time of closure, existing and proposed
environmental controls and the location. Further
information was obtained by performing pump tests that
established the area of influence and the approximate
amount of gas that could be captured from a given
area in the landfill.

Edison

The Edison Municipal Landfill is a closed and uncapped landfill located in Edison, New Jersey. The
methane extraction system was designed to accommodate future environmental controls that would
be necessary for the proper closure of the landfill. The system was installed with modified wellheads
along with a collection system that could be easily sectioned, and quickly dismantled and reassembled
without having to shut down the collection system.

ILR

The ILR Landfill is a closed and capped facility also located in Edison, New Jersey. The landfill was
found to have a very dry waste composition, which is not optimal for gas production. EII resolved
the problem by designing the system to hydrate the waste composition, which ultimately increased
gas production.

MCUA

The Middlesex County Landfill is an operating facility presently accepting approximately 400,000 tons
per year in East Brunswick, New Jersey. The design and construction of this particular methane collection
system required special attention to avoid disrupting the daily activities of the ongoing landfill operation.
To accomplish this, the system was designed and installed in a manner that would allow the entire
system to later be buried by waste.

Jersey Gardens Methane Ventilation System

In the early nineties, the Danish development firm OENJ
Corporation purchased a 166 acre tract of property located in
Northern New Jersey, directly across from the Newark
International Airport. The property is bordered by the Newark Bay
to the East and the New Jersey Turnpike to the West. The site was
a former landfill, which was developed into one of the largest
multi-use shopping malls on the East Coast called the Jersey Gardens Mall.

Edgeboro International Inc. was retained by OENJ to construct an underslab gas ventilation system
consisting of over 30,000 feet of HDPE pipe and fittings as well as placement of over 40,000 tons of stone
at final fine grade.

Edgeboro’s construction commenced following the erection of the steel structure for the Jersey Gardens
Mall. Utilizing three separate union crews, a tight construction schedule was maintained while installing
the network of horizontal methane collection systems, which were placed in the sub base of the floor.
Once installed, Edgeboro was required to leave the sub base within one half of an inch of final grade to
allow the concrete contractor to pour behind the methane collections system.

The methane collection system was designed as an active system to circulate and extract air from under
the concrete floor of the mall, eliminating the possibility of methane gas migrating into the building from
the landfill.

Note: It was estimated that the site, during the construction and final use stages as a multi-use shopping
mall, would create 5,000 full time jobs for the Elizabeth Urban Enterprise zone.

Groundwater Extraction and Treatment System
Belmar, NJ

The project site was previously a Manufactured Gas Plant Site in Belmar, New Jersey. The location was
considered an environmentally sensitive area, which bordered the Shark River. A contaminated
groundwater plume existed on the site that arbitrarily migrated into the Shark River, posing health hazards
for human and marine life.

Working as a subcontractor for Foster Wheeler Environmental Corporation, Edgeboro was retained to
install a pump and treat groundwater extraction system. The intent was to create an inward groundwater
gradient, which would prevent the contaminated groundwater from migrating off the site. The
contaminated groundwater was extracted using a series of vertical wells that utilized special pneumatic
pumps to pump the groundwater to a treatment facility specifically constructed for the site.

Edgeboro was responsible for trenching and installing the network of pumps, piping systems and
groundwater electrical sensors while simultaneously completing the placement of all filtration, control
and mechanical equipment within the treatment facility. Services also included the coordination and
installation of all permits, securing each permit, acquiring utility hookups and running electrical wiring to
all equipment and controls. Edgeboro was also responsible for the plumbing and piping of all filtration
equipment as well as startup procedures.

This process was installed and completed in a congested and heavily traveled area. It required close
coordination to prevent the disruption of the Department of Public Works, recycling center and work being
accomplished adjacent to the municipal park.

Note: The work was required to be constructed during the early spring prior to the summer tourist season.
Despite countless unmarked underground utilities and obstructions, the job was completed in the desig-
nated time frame.

Methane Ventilation System & Vapor Barrier
Loews Cineplex, Elizabeth, NJ

The Loews Cineplex site is bordered by the Newark Bay to the East and the New Jersey Turnpike to the
West. The location of the site was a former landfill, of which a portion was recently developed into a New
Jersey mega-mall. Lowes Cineplex selected the site to build a state of the art movie theater.

Edgeboro International Inc. was retained to construct the environmental controls necessary to protect the
building from methane gas being produced from the underlying landfill.

Edgeboro International Inc. constructed an under slab ventilation system and methane vapor barrier con-
sisting of over 25,000 feet of HDPE pipe and fittings, 7,000 tons of stone at final fine grade and 110,000
sf composite geomembrane vapor barrier layer.

Edgeboro construction commenced following the erection of the steel structure. Utilizing five separate
union crews, Edgeboro coordinated construction schedules with other building contractors on site while
installing the various phases of the methane collection system. Edgeboro was required to leave the sub
base systems within one half of an inch of final grade to allow the concrete contractor to follow
immediately behind the methane collections system installation.

The methane collection system was designed as an active system to circulate and extract air from under
the concrete floor of the Cineplex, eliminating the possibility of methane gas migrating into the building
from the landfill.

Liquid Vapor Barrier, Costco Wholesale
Neptune, NJ

The site on which the Costco Wholesale building was constructed was originally contaminated
by a small municipal landfill. The gases being released from the waste required additional
safety measures to prevent the gas from migrating into the building.

A 148,000 sf Liquid Boot Vapor Barrier was installed below the slab of the Costco building. The
Liquid Boot Vapor Barrier, unlike traditional membrane barriers which need to be welded
together, created a seamless 60 ml liner that conformed to the detail and penetrations that were
encountered during the application. Liquid Boot is a cold sprayed applied membrane and is ideal for
difficult applications where numerous penetrations and custom detail are present. The Liquid
Boot application excels in this type of environment since it can be quickly sprayed onto penetrations
of any shape or size, producing a gas tight seal that traditional plastic liners would have difficulty
accomplishing.

Warehouse Methane Underslab Ventilation System and
Vapor Barrier

The installation of a Methane Underslab Ventilation
System and Vapor Barrier which included 117 vertical
extraction wells, over 9,500 ft of low flow gas
collection piping systems, more than 16,000 ft of
collection laterals and headers, a ventilation layer
consisting of approximately 12,500 tons of stone at
final grade, 334,000 sf of methane vapor barrier,
methane sensors and alarms, flare and blower
installation, and a gas system balancing and testing.

Jersey City Townhouse Complex

Raritan Riverfront Restoration
East Brunswick, NJ

The river stabilization project is located on
the bank of the Raritan River. This project
was extremely complex from a
regulatory perspective: permits and approvals
from USACE, NJDEP, Tidelands Council,
Soil Erosion and Sediment Control are
among those that were required. The bank
of the river located just downstream of
the NJ Turnpike has been subjected to
erosion and degradation for many years.
Edgeboro International Inc. was contracted for
the remediation efforts to preserve and improve

the environmental quality of this area by stabilizing the river bank. The stabilization design was permitted
and developed by EDI and Sadat Associates Inc. and included the excavation of some of the deposited
material in order to create a 3:1 slope for the 12-18” rip rap placement. Portions of the site preparation
work included the placement of geo-textiles and sand to support the rip rap. The installation of the rip
rap was completed in early 2008. Approximately 3,000 LF of river bank was stabilized as part of this
project. After the environmental remediation work was finished, the area was landscaped to restore its
natural habitat. Only native trees, shrubs and grasses were selected for the landscaping project.

Enclosed Methane Flare Systems

SCFM John Zink Utility Flare was necessary
to properly control the methane gas generated
from the landfill as well as maintain
compliance with Title 5 and GHG regulations.
To allow for the proper control as well as the
balancing and monitoring of the gas collection
system and flares, a state of the art PLC control
and Lantec monitoring system was developed
and integrated into the flare station. Each flare
blower has a variable speed drive motor which
is controlled by the PLC to allow the landfill technician to maintain a set gas flow or vacuum on the well
field and individual flares.

Slot Drain Leachate Collection System
East Brunswick, NJ

Edgeboro International Inc. was contracted to construct a leachate collection system utilizing a
biopolymer deep trenching method and a pneumatic pumping system for the Edgeboro Landfill in East
Brunswick, New Jersey.

Edgeboro Disposal Inc. in conjunction with Sadat Associates Inc. engineered a 6,600 LF leachate
collection trench that includes a collection piping system, pump and clean-out stations and metering
chamber. EII was selected and successfully constructed the project.

The system was designed by integrating a biopolymer trenching method to support the following:

• Maintain the stability of the existing bentonite cut-off wall during the construction of the new
leachate collection system

• Minimize dewatering operations
• Minimize the volume of excavated waste
• Improve long term maintenance procedures
• Minimize decomposed waste odors emanating from an open trench
• Less exposure to waste and improved trench safety for construction workers
• Improve the containment system to provide a better inward hydraulic gradient against the cut-off

wall (i.e. leachate levels inside the cut-off wall needed to be lower than groundwater elevations
outside the cut-off wall)

Gas Collection System Modification
East Brunswick, NJ

The Edgeboro Landfill Gas Collection System
Modification Project required a complete redesign
of the existing methane gas collection system to
accommodate the Middlesex County Utilities
Authority Cell Expansion. The new cell expansion
was to be constructed on top of a large closed
portion of the Edgeboro Landfill, which would
cover approximately half of the existing gas
collection system. Major concerns were raised by
both the NJDEP and EPA both of which needed to
approve the new design. The system was specifically designed to allow for the excessive weight of the
new waste material and construction activities that will take place above while allowing the gas to be
routed to the perimeter of the landfill. All the existing wells and collection system had to be incorporated
into the new system. A specially designed gas management plan and temporary portable flares were
utilized to ensure that gas was being effectively collected throughout the entire gas collection system
during construction. The gas collection system modification included over 5,000 LF of new 18” HDPE
gas collection header, 12,000 LF of lateral pipe work and 26,000 lf perforated extraction piping. The
piping was installed in special collection trenches, filled with clean stone and covered with over 1,000,000
Ft2 of liner and geo-textile fabric to ensure the system performed properly and allow for the gas to be
immediately collected once completed without oxygen being pulled into the system contaminating the
gas. The project was completed in an expedited schedule to allow the cell expansion to commence.

Carlstadt Warehouse 10 Mil Taped Liner & PVC System
Carlstadt, NJ

The Meadowlands Distribution Center was an existing building utilizing a vapor mitigation system that
changed owners/tenants requiring amendments to the current system that was in place. The Meadowlands
Distribution Center was split into a number of different units, each having their own necessary floor plans.
Saw cuts to the existing slab allowed for the running of plumbing lines, electrical conduit and/or other
utilities, however, it also damaged the existing gas vapor barrier liner system.

Edgeboro International Inc. was contracted to perform liner repairs utilizing the existing geo-textile/10
mil liner. Care was taken in re-grading the aggregate layer, uncovering the existing liner layer and properly
tape sealing the new spec’d liner according to the manufacturer’s recommendations. All penetrations were
then properly sealed and inspected. After the system was repaired, concrete followed and the new under
slab utilities were placed while maintaining the integrity of the gas vapor barrier.

The Ivy at Shrewsbury Lux Townhomes
60 Mil Spray Applied System with PVC Venting

Situated in a prime location along Shrewsbury Avenue, the new Ivy at Shrewsbury Lux Townhomes
provide a distinctive private luxury community with numerous nearby amenities. The site was originally
the location of a bus maintenance facility and the redevelopment of the area required the installation of a
Geo-Seal gas vapor barrier to each of the 61 townhomes.

Edgeboro International Inc. utilized the necessary equipment and labor to install approximately 70,000
ft2 of Land Science Technology’s 60 mil Geo-Seal gas vapor barrier system to each unit footprint. Both
the BASE geo-textile and BOND geo-textile protection course utilizes a thermally bonded liner, which
provides redundant protection to the 60 mils of spray applied CORE material.

With many tight areas consisting of many banks of penetrations, the spray applied product offers
exceptional protection in a time efficient manner. A smoke test confirmed that the system was properly
installed and free from defects.

Sub Base Preparation Stone Venting Layer & PVC

FEDEX Ground C-14 Hub Expansion
30 Mil Battened & Welded Gas Vapor Barrier with PVC
Underslab
Woodbridge, NJ

The FedEx ground facility in Keasbey, NJ is a major ground shipping hub that receives millions of
packages a year. The ever growing demand for packaged goods forced FedEx to expand its operations on
site by constructing additional wings to the existing Hub. The expansion consisted of approximately 9,000
ft2 of new construction strictly designed for office space, which required the installation of a gas vapor
barrier.

Edgeboro International Inc. utilized the necessary equipment and labor to install a Solmax 30 mil PVC
battened and welded gas vapor barrier. After the installation of the PVC sub slab venting system in the
aggregate layer, Edgeboro placed a non-woven geo-textile to protect the PVC liner from angular stone.
The entire concrete perimeter edge was drilled every 6” to accept a stainless steel anchor bolt. The liner
was laid out and fastened along the perimeter with stainless batten bar, rubber gasketing and anchor bolts.
Chalking around the battening was also performed. All seams, penetrations, overlaps, etc. were welded
using both thermal and chemical techniques. Specialized tensiometer equipment was required to perform
extensive QA/QC practices on the welds, including both shear and peel strength tests for both welder
calibration and destructive tests. An air lance test, visual inspection, perimeter caulking and geo-textile
protection course rounded out the vapor barrier installation.

Wegmans Food Markets, Inc.
60 Mil Spray Applied Barrier with Geo-Composite & PVC Venting
Burlington, MA

As part of Nordblom’s redevelopment of 3rd Avenue in Burlington, Massachusetts, a new 140,000 ft2
Wegmans grocery store was erected. A Geo-Seal sub slab ventilation system and gas vapor barrier was
required for the building. Edgeboro International Inc. utilized equipment, materials, and labor necessary
to install the system in an efficient manner, working in and around other trades. Edgeboro’s knowledge
coupled with the GC’s cooperation allowed the system to be spray applied during the cold winter months.

A network of over 4,300 lf of Geo-Seal’s Vapor Vent HD was placed in the existing stone layer and
provided a pathway for any and all vapors to collect. A series of 14 risers allowed for ventilation to the
atmosphere. Sampling stations were also incorporated into the sub slab venting system for quality control
purposes. Both the BASE geo-textile and BOND geo-textile protection course utilizes a thermally bonded
liner, which provides redundant protection to the 60 mils of spray applied CORE material. A smoke test
confirmed the system was properly installed and free from defects. Proper coordination of the horizontal
and vertical applications with the other trades behind, ahead and above allowed for proper phasing and
management during the installation process.
