Prepare the substrate so that surfaces are well compacted, geotechnically stable with a smooth, uniform surface.
It is important to ensure that the CC is jointed at every overlap between layers and that those layers are fixed to the substrate.
It is important to prevent water or wind ingress between the CC and the substrate, both around the perimeter of the installation and along the joints.
It is important to properly hydrate CC, using enough water for the quantity of material used and allowing for drying conditions.
