Product Description:
FUYUN GCL (bentonite waterproof geosynthetic clay liners) also named bentonite composite waterproof blanket or pad has four layers which 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.
1 Bentonite GCL is self-attaching and self -sealing to concrete or other construction structures.
2 It is made of a non-woven geotextile, a natural sodic bentonite layer, with or without a pe geomembrane layer, and a polypropylene sheet.
3 These layers are connected with a dense felter that makes the bentonite a self-confinement with controlled expansion. With this system it is possible to avoid slippage and the accumulation of bentonite as a consequence of cuts, tears, vertical applications and movements.
FUYUN GCL can be constructed under the negative temperature (-20℃), while the traditional waterproof material cannot, because bentonite is inorganic material having better durability than that of organic waterproof material.

Installing Note:
1, Before GCL construction, foundation should be inspected, the foundation should be rammed flat, no potholes or water, no gravel or roots or other sharp objects.
2, In the process of handling and construction, GCL should be to avoid vibration and impact, to avoid large degree of bending.
3. After installing and acceptance of GCL, backfill shall be carried out as soon as possible. If it is in conjunction with the use of HDPE geomemes, geomemes shall be installed and welded in time to prevent them from being wet or broken by rain.
Advantage:
- good resistance of strong compactness
- long-term performance of waterproof
- environmental friendly material
- stable function in extreme air temperature
- construction period short and simple construction
