Civil Engineering Products

J Carpenter Environmental, LLC sells geosynthetic liner products produced by GSE Lining Technology, Inc., which has the largest selection and highest quality geosynthetic products on the market.

Geomembranes: GSE uses the highest quality resins to manufacture high-density polyethylene (HDPE) and linear low-density polyethylene (LLDPE) geomembrane products. They are available in black, green, or white. Geomembranes are also available with a conductive upper surface and on smooth or textured surfaces, single or double-sided.

Geosynthetic Clay Liners (GCLs) combine geosynthetics with sodium bentonite clay to form a highly impermeable barrier that replaces thick layers of expensive compacted clay. GSE offers two GCL products; a geomembrane-supported GCL and a fabric-encased GCL.

Geonet and Geocomposite products complement or replace sand, stone, and gravel for drainage and base layers. These products are best for erosion control, foundation wall drainage, landfill leachate collection, leak detection, caps and closures, methane gas collection, pond leak detection, roadway and pavement drainage, and other subsurface drainage system applications.

Nonwoven Geotextiles are polypropylene, staple fiber, and needle-punched geotextiles engineered for filtration, soil stabilization, separation, drainage and gas transmission, cushion, and liner protection applications. The products range from 4 oz/yd2 to 32 oz/yd2 mass per unit area.
