Geonets are typically formed by two bi-planar sets of relatively thick, parallel, polymeric (usually polyethylene) ribs bonded in such a way that the two planes of strands intersect at a constant acute angle, forming a diamond-shaped pattern. They can also be manufactured in Tri-Planar configuration. Geonets are used extensively in drainage applications and as leak Geonet & Geocomposite

Geotextiles are permeable fabric materials manufactured from either Polypropylene or Polyester. There are three main types of geotextiles – non woven, woven or heat bonded. Woven geotextiles are commonly used as a structural fabric for reinforcement applications. Non-woven geotextiles are used for separation, drainage/filtration or for protection/ cushioning (protecting a geomembrane liner). Geotextiles are commonly Geotextiles

PVC liners are typically very flexible and readily conform to subgrade contours. Easy to seam. Can be factory-fabricated, folded and flaked. UV stabilised. Common uses are pond linings, tank liners and grain cover applications.

A GCCM is a factory assembled geosynthetic composite consisting of a cementitious layer contained within one or multiple layers of geosynthetic materials. The cementitious portion of the GCCM becomes hardened when properly hydrated. GCCM is a flexible, concrete-filled geosynthetic that hardens on hydration to form a thin, durable, waterproof and low-carbon concrete layer. Common applications Geosynthetic Cementitious Composite Mat (GCCM)

Geocells are honeycomb looking structures commonly manufactured from High-density polyethylene (HDPE). They are designed to be filled with soils, granular, and other infill materials. The perforated honeycomb structures when stretched can provide stability by restricting the vertical and lateral movement of the infill material which in-turn prevents events such as landslides. Common applications are erosion Geocell

Geosynthetic clay liners (GCLs) are manufactured liners consisting of two needles punched geotextile layers encapsulating a layer of sodium bentonite for sealing applications. Can be manufactured with a PE (polyethylene) layer either laminated or coated to provide an additional barrier. Common uses are landfill secondary liners, landfill capping systems, tailings dams, groundwater protection, canals and GCL (Geosynthetic Clay Liner)

Bituminous geomembrane, known as BGM liner, is a specialty geomembrane with composite layers that make it stronger, more watertight and more durable than resin-based geomembranes. Outstanding UV resistance. Its layers consist of an anti-root film with a glass mat providing high tensile strength; a non-woven geotextile that provides mechanical resistance to punctures and tears; and BGM (Bituminous Geomembrane)

Outstanding UV and ozone resistance. Good performance at low temperatures. Good resistance to chemicals, acids and oils. CSPE is an excellent floating cover and lining material with one of the best weathering warranties available. Chlorosulfonated Polyethylene (CSPE) geomembrane and cover materials are highly UV stabilized. CSPE has been used as a lining and cover material CSPE (Chlorosulfonated Polyethylene) & CSPE-R (scrim reinforced)

EIA geomembrane products have a wide spectrum of chemical resistance. EIA-R geomembranes also exhibit impressive dimensional stability, tensile strength and puncture resistance. EIA is flexible and can be prefabricated. Withstands a broad range of chemicals with little or no deterioration of physical properties. Common uses are water storage, brine ponds, waste storage, tank farms, tunnel EIA (Ethylene interpolymer alloy) PVC resin alloyed with Elvaloy™

Can be factory fabricated – folded and flaked. Excellent multiaxial strain properties. Good conformability. Broad seaming temperature window. FPP liners are very flexible and have excellent dimensional stability. FPP geomembranes have low crystallinity and are not affected by traditional environmental stress cracking. Black FPP geomembranes exhibit outstanding weatherability. High hydrostatic puncture resistance. Common uses are F-PP (Flexible Polypropylene) & F-PP-R (scrim reinforced)
