Concrete Cloth (CC) is a unique proprietary material that has recently been developed by Concrete Canvas. It has a very wide range of applications throughout the military and civil engineering industry.

CC consists of a 3-dimensional fibre matrix containing a specially formulated dry concrete mix. A PVC backing on one surface of the cloth ensures the material is completely waterproof; while hydrophilic fibres on the opposite surface aid hydration by drawing the water into the cement. After hydration, CC hardens to a strong, durable, water proof and fire proof concrete surface.

The material can be hydrated either by spraying or by being fully immersed in water. Once hydrated the material is workable for 2 hours and remains flexible. It can be easily nailed, stapled through or coated with an adhesive, for easy attachment to other surfaces and has good drape characteristics allowing complex surfaces with a double curvatures to be produced.

Once set, the fibres reinforce the concrete, preventing crack propagation and providing a safe plastic failure mode.

Key benefits:

  

  • Rapid

    After hydration, Concrete Cloth remains workable for 2 hours and hardens to 80% strength within 24 hours. Fast setting variants are in development.

  • Easy to use

    Dry Concrete Cloth can be cut or tailored using simple hand tools. The PVC side can be supplied with an adhesive backing and bonds well to concrete or brick surfaces when set.

  • Flexible

    Concrete Cloth has good drape characteristics allowing it to take up the shape of complex surfaces including those with a double curvature.

  • Strong

    The fibre reinforcement acts to prevent cracking, absorb energy from impacts and to provide a stable failure mode.

  • Fire proof

    Concrete Cloth is a ceramic and will not burn.

  • Water proof

    The PVC backing on one surface ensures that Concrete Cloth is completely waterproof and chemically resistant.

  • Adaptable

    Concrete Cloth is currently supplied on 1.1m wide rolls but can be manufactured with a roll width of up to 5m. The cloth can be produced in a range of thicknesses from 5-20mm.

  • Durable

    Concrete Cloth is chemically resistant, has good weathering performance and will not degrade in UV.
