Flexible, cement impregnated fabric that hardens when hydrated to form a thin, durable, water and fire proof concrete layer.
Concrete Cloth (CC) allows construction without the need for plant or mixing equipment.
Simply position the cloth and add water - workable for 2 hours and hardens to 80% strength within 24 hours.
CC is available in 3 thicknesses and in man-portable rolls for applications with limited access or where heavy plant equipment is not available.
Concrete Cloth (CC) is a flexible cement impregnated fabric that hardens on hydration to form a thin, durable water proof and fire proof concrete layer.
Essentially, it's concrete on a roll Just Add Water.
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 hydratred. It will set in fresh and sea water.
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.
CC has good drape characteristics, allowing it to take up the shape of complex surfaces including those with a double curvature.
Unset Cloth can be cut or tailored using basic hand tools.
The fibre reinforcement prevents cracking, absorbs energy from impacts and provides a stable failure mode.
CC is chemically resistant, has good weathering performance and will not degrade in UV.
The PVC backing on one surface ensures that the material is completely water proof and chemically resistant.
CC is a ceramic and will not burn.
Concrete Cloth (CC) is the only way of laying a thin concrete layer from a prefabricated roll of material.
This enables up to 150 mm of poured concrete to be replaced with just 8 mm for many surfacing applications.
As a result, material savings of 95% can be achieved for a typical construction project.
This directly reduces the CO2 footprint of construction work not only through material savings but also through reduced road transport and time on-site.
CC traps dry concrete powder in a 3-dimensional fibre matrix. Testing based on BS8443 to indicate the effect of underwater setting, shows that CC loses only 3% by mass.
By comparison, specialized underwater concretes typically lose between 10-15% while also requiring much larger volumes to be poured.
CC uses a specialized high early strength concrete with a limited alkaline reserve. Unlike most concretes, it is not classified as an irritant and is less damaging to the environment.
CC was approved for use by the Environment Agency (EA) Biodiversity team in 2010 for the Church Village Bypass Project.
Benefits cited included ‘surface roughness to provide diversity in the channel's morphology’ and its ability to introduce ‘sinuosity in the channel line’.
Several projects have since been granted approval on a case-by-case basis and the EA recently purchased CC directly for internal use as a weed inhibitor.
Untreated CC will naturally ‘green’ over time as the textured top surface allows moss growth, whilst the fibre-reinforced concrete layer will prevent root-growing vegetation, which would otherwise restrict water flow and increase maintenance costs.
