Concrete Canvas

Concrete Canvas (CC), is a flexible, concrete impregnated fabric that hardens when hydrated to form a thin, durable, waterproof concrete layer. CC allows concrete construction without the need for plant or mixing equipment. Simply position the Canvas and just add water. CC consists of a 3-dimensional fibre matrix containing a specially formulated dry concrete mix. A PVC backing on one surface of the canvas ensures the material is waterproof. The material can be hydrated either by spraying or by being fully immersed in water. Once set, the fibres reinforce the concrete, preventing crack propagation and providing a safe plastic failure mode. CC is available in 3 thicknesses: CC5, CC8 and CC13, which are 5, 8 and 13mm thick respectively.

Concrete Canvas (CC) key facts:

Easy to use 
CC is available in man portable rolls for applications with limited access or where heavy plant equipment is not available. There is no need for mixing or measuring, the concrete is premixed and cannot be over hydrated. It will set underwater and in sea water
Rapid 
Once hydrated, CC remains workable for 2 hours and hardens to 80% strength within 24 hours. Accelerated or retarded formulations can be produced to meet specific customer requirements
Flexible
CC has good drape characteristics allowing it to take up the shape of complex surfaces including those with a double curvature. The unset cloth can be cut or tailored using basic hand tools
Strong 
The fibre reinforcement prevents cracking, absorbs energy from impacts and provides a stable failure mode
Durable 
CC is chemically resistant, has good weathering performance and will not degrade in UV
Waterproof 
The PVC backing on one surface ensures that the material is completely waterproof and chemically resistant
Fire-resistant 
CC is fire-safe, does not contribute to the surface spread of flames, has a low level of smoke development and minimal hazardous gas emissions. CC has achieved Euroclass classification B-s1, d0.
