Product Description

Sub-headline: Stop Leaks Before They Start. Effortless, Reliable, Continuous Waterproofing.

Visual Concept: Imagine a flexible, rugged blanket. Sandwiched inside is a layer of powerful, natural sodium bentonite clay. When water touches it, the clay swells dramatically – like a protective gel – instantly sealing punctures, seams, and imperfections. That's the magic of a Bentonite Waterproof Blanket.

How It Works (The Visual Power):

  1. The Core: Sodium Bentonite Clay

    • Think: Millions of tiny, thirsty platelets.

    • Visualize: Dry, granular clay (like coarse sand) contained within a geotextile.

    • The Magic: Upon contact with water, these platelets absorb it rapidly, swelling up to 15 times their original volume.

    • Result: Forms a dense, flexible, low-permeability gel barrier that self-seals around penetrations (like rocks or roots) and overlaps.

  2. The Armor: Reinforcing Geotextiles

    • Think: Tough, fabric skin holding the power inside.

    • Visualize: A strong, needle-punched nonwoven geotextile on one or both sides (like durable felt or landscape fabric).

    • The Function: Provides tensile strength, protects the clay during handling/installation, and allows the bentonite to hydrate uniformly. Some versions have a woven geotextile for extra stability or a geomembrane backing.

Why Choose Our Bentonite Blanket? See the Difference:

  •  Unmatched Self-Healing:

    • Visualize: A nail punctures the installed blanket. Water rushes in, the bentonite swells around the nail, creating a watertight seal within minutes/hours. No complex patching needed!

  • Rapid Installation = Faster Projects:

    • Visualize: Large rolls unfurled like carpet. Simply roll it out, overlap seams, secure with bentonite powder or adhesive tape, and cover. Dramatically faster than compacted clay liners (CCL).

  • Significant Cost Savings:

    • Visualize: Reduced labor time, less heavy equipment needed, minimal specialized skills required. Lower overall installed cost vs. traditional methods.

  •  Superior Performance in Challenging Conditions:

    • Visualize: Performs reliably even on uneven subgrades or in areas prone to minor settling. The swelling clay compensates for irregularities.

  •  Environmentally Preferred:

    • Visualize: Utilizing a natural, abundant clay mineral. Reduces the need for quarried clay and associated transport emissions.

  •  Consistent, Reliable Barrier:

    • Visualize: A continuous, factory-controlled layer of high-quality bentonite, ensuring uniform thickness and performance – unlike variable field-compacted clay.

The Power in Numbers (Visual Impact):

  • Swells up to 15X: 1 lb of dry bentonite can absorb & hold up to 14 lbs of water, forming an impermeable gel.

  • Ultra-Low Permeability: Achieves hydraulic conductivity often less than 5 x 10⁻¹¹ m/s (effectively impervious) when hydrated.

  • High Coverage: Large roll sizes cover vast areas quickly.

Where It Forms the Perfect Barrier (Application Scenes):

  • Beneath Landfills: The critical base liner system, containing leachate.

  • Under Foundations & Basements: Permanent protection against groundwater seepage.

  •  Canals, Ponds & Reservoirs: Lining for water retention and seepage control.

  • Secondary Containment: Around tanks and pipelines for environmental protection.

  •  Green Roofs & Plaza Decks: Reliable root-resistant waterproofing layer.

  •  Tunnels & Underground Structures: Controlling water ingress.
