High Density Polyethylene (HDPE) Liners

• The most widely used Geomembrane in the world. Excellent longevity, UV resistance and chemical resistance.
• In practice, HDPE will be the most suitable geomembrane to be used in the majority of applications.
• HDPE liners can be supplied as smooth, single sided textured and double sided textured and in a standard black colour.

Linear Low-Density Polyethylene (LLDPE) Liners

• The lower density gives improved flexibility and elongation characteristics as a trade-off against slightly poorer UV and chemical resistance performance compound to HDPE.
• LLDPE can be used for prefabricated liners that can be sent to site for client installation.
• LLDPE is suitable for floating covers and landfill caps where greater flexibility is required.
• LLDPE similar to HDPE, can be supplied as smooth, single sided textured and double sided textured in a standard black colour.

GeoTextiles

• Geotextiles are industrial fabrics that can be used both below and above geomembranes for protection from damage.
• While the Geotextiles aren’t always needed, they assist greatly in areas that need protection from rough subgrade and backfilling any Geomembranes.

GeoSynthetic Clay Liners (GCL’S)

• GCL’s are made by sandwiching bentonite clay between two layers of geotextile. Installed properly they are an alternative to a layer of natural clay.
• GCL’s are not suitable for use as a primary liner.
• Their purpose is to replace natural clay in composite (clay & HDPE) lining systems.
• Such composite systems are commonly used in landfills and other environmentally sensitive applications.

COSHH

• CC Hydro (CCH) combines the concrete filled geotextile technology of Concrete Canvas with a highly impermeable, chemically resistant geomembrane liner. The liner incorporates a hi-visibility welding strip which allows joints to be thermally welded with a double-track or triple-track air channel for on-site testing. The product was specifically developed for applications within the Petrochemical and Oil & Gas industries.
• CCH is available in 5mm and 8mm thicknesses: CCH5 and CCH8 respectively.
