Bentonite Waterproof GCL :
1. Improved leakage performance
2. Permanent waterproof performance
3. Simple construction
Geosynthetic clay liners (GCLs) 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.
It is used to prevent water leakages in areas of artificial lakes, waste disposal fields, underground
garage, top building gardens, reservoirs, oil warehouses, and chemicals accumulating fields.
Features:
1. Improved leakage performance
2. Permanent waterproof performance
3. Simple construction and short time limit for a project.
4. Not influenced by air temperature.
5. A kind of green material and good to environmental protection.
6. More versatile than compacted clay
7. Increased airspace and liner efficiency

Projects:
1.What is the production capacity of GCL one day?
Answer: we have two advanced production lines and can produce 10000M2 GCL a day.
2. Do you have any accessories?
Answer: we have a group of accessories for you to choose, such as strips, the bentonite granular for overlap, and also the glue and paste to help you finish the whole project.
3.What is the price of per sqm?
Answer: Because the prices can be different according to different materials and weight and specifications, please consult the sales at first with the clear specifications, or you can tell them the projects and then they can give you some advice.
4. What is the weight range of the GCL?
Answer: it can be ordered by customer’s requirements, we can produce from 3000g-9000g. And we can produce the 3 layers, 4 layers and 5 layers as the customer required.
5. What is the delivery time?
Answer: If the requirements are not so special, we can produce the products and deliver it to the port in 10 days.
