Product Description
Bentonite waterproof liner (GCL) is a new geosynthetic material. Taking natural sodium bentonite as material, bentonite particles are fixed between two layers of geotextile by special process to make bentonite waterproof blanket, which not only has all the characteristics of geotechnical materials, but also has excellent waterproof (seepage) performance.
Specification
1. GCL-NP, GCL-OF;
2. Unit weight: ≥4000g/sm;
3. 4m-6m in roll width;
4.length can be produced as your requirement.
