New Type Bentonite Geosynthetic Clay Liner For Waterproof And Impermeable Needs

Product Introduction

Sodium bentonite waterproof blanket is a new type of environmental protection and ecological composite impermeable material, which mainly uses the physical properties of sodium bentonite to waterproof.

Product Properties

1. Waterproof and impermeable performance: Bentonite waterproof blanket has excellent waterproof and impermeable performance, sodium bentonite can expand more than 24 times in contact with water, forming a uniform colloidal system with high viscosity and low filtration loss, and has strong self-water retention performance.
2. Environmental adaptability: the material is natural inorganic material, will not occur aging reaction, durability is good; Will not cause pollution to the surrounding environment.
3. Construction convenience: The construction is simple, not limited by the temperature of the construction environment, and can also be constructed below 0℃. Just lay the bentonite waterproof blanket flat on the ground, facade or slope during construction, fix it with nails and washers and lap it as required. Simple repair and easy maintenance.
4. Physical properties: good compactness, when the thickness is about 3mm, low permeability, equivalent to 100 times the compactness of 30cm thick clay.
5. Wide width: the width can be up to 6 meters, which matches the specifications of geotextile and geomemofilm, greatly improving the construction efficiency.

Product Application

Widely used in water conservancy, environmental protection, transportation, railway, civil aviation and other civil engineering leakage prevention projects.
