Geomembrane Covers & Liners
A geomembrane is any impermeable membrane used to block the migration of fluids and/or for the containment of hazardous or municipal wastes. These membranes are usually made of synthetic polymers in sheets ranging from 0.01 to 0.14 in. (0.25 to 3.5 mm) thick. Originally used primarily for the
construction of canal and pond liners, geomembranes are now a major application in the prevention of pollution in landfill and surface impoundment construction. There is also widespread use of geomembranes in both aquaculture and decorative pond construction, aswell as other applications.
Geomembranes are often used in conjunction with soil liners, permeable geotextiles, fluid drainage media, and other geotechnical support materials. Each type of geomembrane material has specific characteristics that will affect installation and performance. GSI offers a multitude of material options based on the application of your project.
In addition to material sales, GSI is also a full service installer of geomembrane covers and liners. You can be sure that your project will be completed by experienced, professional installers while saving you money over other installers. With over 20 years of installation experience, we have completed projects in nearly every industry with containment needs. Complex specifications, challenging terrain and tight deadlines are no match for our dedicated teams of project managers, engineers and installation crews.
Geomembrane Featured Projects
Project: Charlotte Whitewater Park Owner: Architect General Contractor
Materials: The U.S. National Whitewater Center (USNWC) is the world's premier outdoor recreation and environmental learning center. Alongside mountain-biking trails, a climbing center, running trails and camping areas, the park's unique feature will be a multiple-channel, customized whitewater river for rafting and canoe/kayak enthusiasts of all abilities. The USNWC is only 10 minutes from downtown Charlotte and provides over 300 acres of woodlands along the scenic Catawba River. |

| inspired by the successful Penrith Whitewater Stadium built for the 2000 Olympics and the stadium built for the 2004 Athens Games, the USNWC will be the world's only multi-channel recirculating whitewater river. The USOC has formally endorsed the center and committed to designating it an Official Olympic Training Site. The national governing body for the sport, USA Canoe and Kayak (USACK) has also designated the Center as its new home. The USNWC will host World Cup competitions, Olympic Trials and also serve as the home of international Olympic athletes working and training at the center. The 3 whitewater channels can be modified to offer diverse levels of difficulty and excitement for kayakers, canoeists and rafters of all levels, allowing for ever-changing configurations of rapids. Multiple channels allow for different uses simultaneously, providing significant flexibility and usage opportunities. For example, firefighters from across the country will train here on lifesaving swift-water rescue skills where they will be able to control their training environment to their own specifications as well as limit the dangers involved in training. |
Project: Tuscany Reserve Golf Course
Location: North Naples, Florida
Developer: WCI Communities, Inc.
Geomembrane Installer: Geo-Synthetics, Inc.
Materials: 40 mil HDPE Geomembrane, 12 oz Geotextile
Quantites: 1,676,000 sq. ft. of each layer, 12,000 l. ft. stainless steel batten and anchor bolts.
Tuscany Reserve is one of the most prestigious developments of WCI Communities, Inc. The golf course within the development has been designed and built in keeping with the very high standards of the community. This includes engaging the services of Pete Dye and Greg Norman to design a beautiful and challenging championship golf course.
The foremost of which was the high groundwater level that made it extremely difficult to maintain the pond excavations dry enough to allow the installation of the HDPE geomembrane and the underlying geotextile. This required unusual and innovative methods of construction/installation by both the earthworks and liner contractors. While the earthworks contractor did a good job of controlling the inflow of groundwater there was always water inflow to contend with during the installation of the geomembrane. This often required elevating the seam areas using polystyrene planks as there was running water under the liner. The other challenge was attaching the liner to the numerous bridges, retaining walls and other structures to prevent water loss once the ponds were filled. All the lined ponds have no measurable loss of water which helps the water management of the course and enhances the beauty of the course as the water level is always at the grass level with no exposure of the cover material. |
