Concrete Canvas

Geosynthetic Cementitious Composite Mat

Concrete Canvas (CC) is a flexible, concrete impregnated fabric that hardens when hydrated to form a thin, durable, water proof and fire resistant concrete layer.

Properties

CC allows concrete construction without the need for plant or mixing equipment. Simply position the Canvas and just add water.

Application

Concrete Canvas is available in 3 thicknesses: CC5, CC8 and CC13, which are 5, 8 and 13mm thick respectively. Concrete Canvas is used in a variety of civil infrastructure applications, such as ditch lining, slope protection and capping secondary containment bunds.

Ditch Lining
Concrete Canvas is rapidly becoming the ditch lining material of choice for engineers and contractors around the world.  Concrete Canvas is typically 10 times faster to install than conventional concrete solutions, with installation speeds of up to 200sqm/hr possible with only a 3 man crew for a longitudinal layup.

Slope Protection
Concrete Canvas is increasingly being used as an alternative to shotcrete to protect slopes from surface erosion caused by weathering, surface run-off and environmental degradation.

In certain applications Concrete Canvas can be used as structural slope stabilisation by combining it with steel mesh and soils nails (see the Concrete Canvas User guide for more details).

Bund Lining
Concrete Canvas can be used for hard armour capping of earth bunds around petrochemical tank farms, munitions depots and flood defenses. Typically installation speeds for bund lining are approximately 800sqm/day with a 6-man crew.

Vent Walls
Concrete Canvas can be used as an alternative to brattice cloth, plaster board or concrete block-work to construct blast and vent wall structures for underground mining applications. Trials have shown that Concrete Canvas typically provides cost savings of over 20% compared to conventional solutions.

Outfalls
Concrete Canvas has been used worldwide as an effective method of preventing surface erosion and scour associated with water run-off from culverts outlets, spillways and over-toppings.

Features

Compared to traditional concrete solutions, Concrete Canvas is faster, easier and, more cost effective to install and has the additional benefit of reducing the environmental impact of concreting works by up to 95%.

  • Rapid Install
    Concrete Canvas can be laid at a rate of 200sqm/hour by a 3 man team.  Typical installation speeds are up to 10 times faster than conventional concrete solutions.

  • Easy to Use
    Concrete Canvas is available in man portable rolls eliminating the need for plant on site and allowing concrete installation in areas with limited  access. Prior to hydration, Concrete Canvas layers can be cut to length using basic hand tools eliminating the hazards associated with using power tools in high risk environments. The concrete is premixed so there is no need for mixing, measuring or compacting. Just add water.

  • Low Project Cost
    The speed and ease of installation mean Concrete Canvas is more cost-effective than conventional concrete, with less logistical burden. Up to 200 square metres of Concrete Canvas can be supplied on a single pallet, greatly reducing transportation logistics and on site storage.

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