CC’s unique formula means it cannot be over-hydrated, allowing installation in wet weather and even underwater. CC produces no back spray, eliminating problems associated with using sprayed concrete or resin based systems around sensitive infrastructure.
CC Hydro™ (CCH) is recommended for lagoon lining projects as it has excellent impermeability and has a hydraulic conductivity better than 1 x 10-11m/s as per independent testing to BS EN 14150. CCH incorporates a high-visibility welding strip, allowing the joint to be thermally bonded with a twin-track air channel for fast and simple on-site pressure testing, and strong, lasting joints.
Prepare the substrate so that surfaces are well compacted, geotechnically stable with a smooth, uniform surface.
It is important to prevent water and wind ingress between the CC and the substrate, both around the perimeter of the installation and along the joints.
It is important to ensure that the CC is jointed at every overlap between layers and that those layers are fixed to the surface.
It is important to properly hydrate CC, using enough water for the quantity of material used and allowing for drying conditions.
