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

Failing concrete must be cleaned and mortar applied to larger cracks (typically anything larger than 50mm in any direction) to eliminate voids under the CC. A suitable geotextile may also be used.

Any loose soil, rocks, concrete debris and vegetation should be removed.

If the perimeter edge of the CC is terminating in a soil substrate (i.e. it is not going to be connected to the concrete structure), excavate anchor trenches along the perimeter of the structure (Leading and Trailing edges, crest/side slopes).

Anchor trench dimensions must be a minimum of 150mm x 150mm but may need to be increased to suit designer’s requirements.

Dispense CC from bottom of roll.

Drill driver and through bolts, concrete screw anchors or alternative approved method to join the CC layers.

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

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