Geosynthetic Clay Liner Needle-punched reinforced geosynthetic clay liners are extremely versatile clay-based lining products with two geotextile layers encapsulating a layer of sodium bentonite resulting in a very strong and robust product for sealing applications. The bentonite clay gives the GCL its self-healing properties, should an object puncture the membrane the bentonite clay will swell over the damaged area thereby repairing itself. Installation is quick and easy, simply unroll on-site and overlap at the joints. From a logistical point of view, the advantages are also easy to see, one truckload covers 4,000m² compared with only 40m² (500mm thick) for a load of clay. Geomembranes Geomembranes are widely used for the containment of liquids, solids and gases in a variety of construction applications. We have substantial experience and knowledge of containment engineering supplying membranes manufactured from HDPE, LLDPE, EPDM, PP or Butyl amongst others as well as our own Aztex Attenuation Membrane. These products can also be made in several different thicknesses with either a textured or smooth finish. They provide a complete seal against even the most toxic substances, they can be delivered to site cut to bespoke sizes tailored to specific project requirements making installation quick and easy without the need for on-site welding. Attenuation tank geomembranes and geotextiles can also be prefabricated to suit specific tank dimensions. Applications Ponds Lakes Lagoons Contaminated land Landfill (caps and lining) Attenuation tanks Benefits Quick and easy to install Can reduce construction costs by replacing compacted clay Withstands differential settlement Self-sealing overlaps Installation advantages with 5m wide rolls Prefabricated panels to suit specific project requirements Contact us Got a question?
