Concrete Canvas^® (CC) is the original Geosynthetic Cementitious Composite Mat (GCCM) and the first product to declare conformance to ASTM D8364 ‘Standard Specification for GCCMs’. It is a flexible, concrete filled geotextile that hardens on hydration to form a thin, durable and waterproof concrete layer. Essentially, it can be described as Concrete on a Roll^® and is used for a wide variety of applications including the lining of secondary containment bunds to provide erosion control, weed suppression, protecting against animal damage and reducing maintenance.

• Sufficient CC to complete the project including allowance for edge fixings, overlaps
• Suitable lifting equipment to dispense CC Bulk, Batched or CC Wide Rolls
• Safety mask and gloves
• Cutting equipment, utility knife or disc cutter
• Metal or plastic fixing pins and lump hammer
• For jointing CC: Screwdriver, stainless steel screws and sealant or alternative approved method to join the CC layers. See the CC Equipment List for full details.
• For ordering, offloading and storage information, see the CC Logistics Guide for full details.
• Dust hazard. Wear appropriate PPE. Consult CC & CCH SDS

• Remove vegetation and grade the bund to a uniform profile to suit the design dimensions.
• Remove sharp or protruding rocks >25mm and fill large voids.

Consult the construction drawings to verify if special subgrade preparation measures such as minimum bearing capacity requirements, installation of a non-woven geotextile, or if subgrade drainage details are needed.

CC must be placed to ensure direct contact with the surface to prevent void space.

Overlaps must be shingled in the direction of water flow.

Use stainless steel screws and sealant or alternative approved method to join the CC layers.

Ensure the CC is fully saturated. Spray the fibre surface multiple times until the CC is fully saturated.
