- Superior Compactness: Sodium bentonite forms a high-density diaphragm with permeability equivalent to 100 times that of 30cm thick clay liner
- Permanent Waterproof Performance: Natural sodium bentonite-based inorganic material resists aging and corrosion over time
- Easy Installation: Simple construction process without heating or pasting requirements
- Temperature Resistance: Maintains performance in cold weather conditions without brittleness
- Self-Repairing Capability: Bentonite expands 20-28 times to repair cracks up to 2mm in concrete surfaces
- Environmentally Friendly: Natural inorganic material that is non-toxic and harmless to the environment
Ideal for environmental engineering projects including landfill emissions control, underground reservoirs, infrastructure construction, and sealing solutions requiring effective segregation and anti-leakage protection.
Available in custom roll dimensions according to customer requirements, with flexible square meter coverage per roll and estimated weight specifications.
