Geosynthetic Clay Liners (GCL) are high-performance needle punched environmental reinforced composites which combine two durable geotextile outer layers with a uniform core of natural sodium bentonite clay to form a hydraulic barrier. Fibers from the non-woven geotextile are needle punched through the layer of bentonite and incorporated into the other geotextile (either a woven or non-woven). when hydrated under a confining load, the bentonite swells to form a low permeability clay layer with the equivalent hydraulic protection of several feet of compacted clay.
Our bentonite waterproof blanket can be constructed under extreme low temperature (-20℃) where the traditional waterproof material cannot be constructed, Because bentonite is inorganic material, its durability is better than that of organic waterproof material.
Sodium bentonite-based GCLs provide an excellent hydraulic barrier in applications where leachate in direct contact with the GCL is relatively non-aggressive, or in composite lining applications where the GCL is overlain by a thermally welded geomembrane and hydrates from uptake of innocuous moisture from the subgrade.
1, bentonite waterproof geosynthetic clay liners construction, foundation should be checked and inspected, the foundation should be rammed flat, no potholes and water, no gravels, no roots and other sharp objects.
2, bentonite waterproof geosynthetic clay liners in the process of handling and construction should be to avoid vibration and impact, to avoid the blanket body having a large degree of bending.
3. After the installing and acceptance of GCL, backfill shall be carried out as soon as possible. If it is in conjunction with the use of HDPE geomembrane, which shall be installed and welded in time to prevent it from being wet or broken by rain.
