CC 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 rapid lining of drainage channels, providing slope protection, weed suppression, culvert repair and general concrete remediation.

• Sufficient CC to complete the project including allowance for edge fixings and overlaps
• Suitable lifting equipment to dispense CC Bulk or Wide Rolls
• Safety mask and gloves
• Cutting equipment, utility knife or disc cutter
• Metal or plastic fixing pins
• Lump hammer
• Screwdriver, stainless steel screws and suitable sealant with applicator gun, or alternative approved method to join the CC layers
• Water supply
• 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 the CC Safety Data Sheet document

• Remove all vegetation and grade surface to a uniform profile to suit the design dimensions.
• Remove sharp or protruding rocks >25mm and fill large voids >50mm.

Apply herbicidal treatment (if specified by the project engineer).

If the perimeter edge of the CC is terminating in a soil substrate (i.e. it is not going to be connected to existing infrastructure), excavate perimeter anchor trenches/benches to capture all CC edges.

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

Remove packaging (making sure to note the Roll ID) and unroll CC across the coverage area to suit the specified layup (longitudinal or transverse layup as specified on the design drawings), ensuring the fibrous top surface faces upwards, with the PVC membrane in contact with the ground.

Screwdriver, stainless steel screws and suitable sealant with applicator gun, or alternative approved method to join the CC layers.

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