The Sodium Bentonite Waterproof Blanket is a highly effective, eco-friendly waterproofing solution designed for a wide range of construction and environmental applications. Composed of natural sodium bentonite clay sandwiched between geotextile layers, this waterproof blanket offers superior self-sealing properties, durability, and ease of installation. It is an ideal choice for projects requiring reliable and long-lasting waterproofing, such as landfills, ponds, tunnels, and foundations.
Key Features:
Self-Sealing Properties:
Sodium bentonite clay swells upon contact with water, forming a dense, impermeable barrier.
Automatically seals cracks and gaps, ensuring continuous waterproofing.
Natural and Eco-Friendly:
Made from 100% natural sodium bentonite, a non-toxic and environmentally safe material.
Free from harmful chemicals, making it suitable for potable water applications.
High Durability:
Resistant to punctures, tears, and UV degradation.
Withstands harsh environmental conditions, including freeze-thaw cycles.
Easy Installation:
Lightweight and flexible, allowing for quick and straightforward deployment.
Can be easily cut and shaped to fit complex geometries.
Cost-Effective:
Reduces the need for additional waterproofing materials and labor.
Provides long-term performance with minimal maintenance.
Versatile Applications:
Suitable for a wide range of waterproofing and containment projects.
Compatible with various substrates, including concrete, soil, and geosynthetics.
