Versatile Sodium Bentonite Geosynthetic Clay Liner For Waterproofing Projects
Product Introduction
Sodium bentonite waterproof blanket is a new type of environmentally friendly geomaterial, which is composed of sodium bentonite particles sandwiched between two layers of geotextile. It immobilized bentonite particles by needling, laminating or gluing processes to form a blanket material with excellent waterproof performance.
Product Properties
1. High expansibility: sodium bentonite can expand rapidly in contact with water to form a waterproof gel.
2. Low permeability: has very low permeability, up to 5×10^-11m/s.
3. Durability: As a natural inorganic material, it has good aging resistance and chemical corrosion resistance.
4. Environmental protection: non-toxic and harmless, can be naturally degraded, friendly to the environment.
5. Simple construction: easy to transport and construction, no special equipment is required.
