1.Comprising of a Geosynthetic Clay Liner (GCL) 2.Fibre Reinforced 3.PE(Polyethylene) sheet backing bonded to the geotextile

Description:

 

1. YHSY BM is a waterproofing membrane comprising of a Geosynthetic Clay Liner (GCL) composite made from high quality polypropylene geotextiles and a premium grade sodium bentonite granules.

 

2. BM is fully fibre-reinforced by fully needle-punching across the full length and width of the product.

 

3. BM has a two micron PE (Polyethylene) sheet backing bonded to the geotextile.

 

4. This product is designed for use in situations requiring protection against contaminated or saline water.

 

5. BM has more bentonite granules per m2.
