Geomas Bentoshield - Bentonite Membrane

Introducing the Geomas Bentoshield Membrane: High-Performance Waterproofing Now Available from Clever Shield

Clever Shield is proud to announce the addition of the Geomas Bentoshield Membrane to our growing range of advanced waterproofing and protective solutions. Designed for demanding construction and civil engineering applications, this innovative geosynthetic clay liner (GCL) sets a new benchmark in below-ground waterproofing performance.


What is the Geomas Bentoshield Membrane?

The Geomas Bentoshield is a high-spec geosynthetic clay liner composed of a layer of natural sodium bentonite encased between durable geotextiles and reinforced to ensure strength and stability. When hydrated, the bentonite swells to form a dense, impermeable gel that self-seals around penetrations and minor punctures—delivering a long-lasting, robust waterproof barrier.

Ideal for use in foundations, basements, retaining walls, tunnels, and other critical below-ground structures, this membrane combines ease of installation with superior protection, reducing long-term risk and cost.


Key Benefits:

  • Self-Sealing Performance: The natural swelling ability of bentonite allows the membrane to seal small gaps or punctures automatically, ensuring maximum protection without costly rework.

  • Fast, Efficient Installation: Lightweight, flexible, and easy to handle, the Bentoshield system significantly reduces installation time and complexity on-site.

  • Environmentally Friendly: Made from naturally occurring materials, the membrane offers a sustainable solution with a minimal environmental footprint.

  • Versatile Application: Suitable for both vertical and horizontal installations across a wide range of soil and site conditions.
