Heavy Duty Bentonite Waterproof Blanket for Large-scale Projects with High Tensile Strength
Product Description
Bentonite Waterproof Blanket - Heavy Duty Anti-seepage Material for Large-scale Projects
Product Introduction
This heavy-duty bentonite waterproof blanket is engineered for large-scale, high-load infrastructure projects. It features a multi-layer composite structure comprising high-strength woven geotextile, thickened bentonite layer, and geogrid reinforcement. The product delivers exceptional tensile strength, tear resistance, and load-bearing capacity, capable of withstanding heavy machinery pressure and extensive backfill soil loads.
Key Features
Ultra-high mechanical strength: Tensile strength ≥ 80kN/m, tear strength ≥ 15kN, designed to withstand heavy machinery pressure and large backfill loads
Thickened impermeable layer: Bentonite layer thickness increased to 6-8mm for superior expansion capacity and enhanced impermeability
Excellent dimensional stability: Resists shrinkage and deformation under long-term load, maintaining waterproof layer integrity
Adaptable to complex terrain: Can be laid on irregular base surfaces and accommodates uneven settlement in large-scale projects
Application Fields
Ideal for large-scale landfills, artificial lakes and reservoirs, coastal reclamation projects, industrial parks, and high-speed railway subgrade anti-seepage applications. Particularly suitable for projects requiring extensive laying areas and heavy load bearing capacity.
Installation Guidelines
Base surface preparation: Reinforce base surface with geotextile to enhance bearing capacity. Ensure surface is flat, compacted, and free of protrusions
Mechanical laying: Utilize professional laying machinery for large-area installation. Maintain 30cm overlap width between blankets and compact overlap areas with heavy rollers
Secure anchoring: Fix with high-strength anchor bolts at 1m spacing. Cover bolt heads with bentonite caps to prevent water seepage
Layered backfilling: Backfill in 30-50cm layers, compacting each layer with rollers. Use cushion layer protection to prevent direct heavy machinery contact with waterproof blanket
