Concrete Canvas® rolls, used to line channels, protect slopes or remediate concrete structures, are now available through Kaytech.

Kaytech has been appointed as a distributor for Concrete Canvas® to supply Geosynthetic Cementitious Composite Mats (GCCM) to the South African civil engineering industry, including road and rail applications.

Concrete Canvas® is used specifically for the lining of culverts, channels, slope protection and the remediation of existing concrete structures.  

As part of a revolutionary new class of construction materials, these GCCMs are made from a flexible, concrete impregnated fabric that hardens on hydration to form a thin, durable, waterproof and fire-resistant concrete layer. Essentially, it’s concrete on a roll. Concrete Canvas® allows concrete construction without the need for plant or mixing equipment. The mat is simply positioned and then water is added.

Concrete Canvas® consists of a three-dimensional fibre matrix containing a specially formulated dry concrete mix. A PVC backing on one surface of the mat ensures the material is completely waterproof. The material is 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. Concrete Canvas® is available in two thicknesses: CC5™and CC8™, which are 5mm and 8mm thick respectively.

Rapid install
Concrete Canvas® can be laid at a rate of 200m²/hour, which is up to ten times faster than conventional concrete solutions.

Easy to use
It is available in shorter rolls that are manageable by hand for applications with limited access. The concrete is pre-mixed so there is no need for mixing, measuring or compacting. One just needs to add water.

Lower project costs
The speed and ease of installation leads to Concrete Canvas® being more cost-effective than conventional concrete, with less logistical complexity.

Concrete Canvas® is a low-mass, low-carbon technology, which uses up to 95% less material than conventional concrete for many applications.

Waterproof
The PVC backing on one surface of the GCCM ensures that the material has excellent impermeability.

Strong
The fibre reinforcement prevents cracking, absorbs energy from impacts and provides a stable failure mode.

Durable
Concrete Canvas® is twice as abrasion-resistant as standard OPC concrete, has excellent chemical resistance, good weathering performance and will not degrade due to ultraviolet (UV) irradiation.

Flexible
Concrete Canvas® has good drape characteristics and will closely follow the ground profile and fit around existing infrastructure. Unset Concrete Canvas® can be cut or tailored using basic hand tools.
