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.
