Bond coats are a good choice for adding a levelling layer of concrete on the road for repair work.
The bond coat acts as the adhesive glue between the two concrete layers, creating a structure that performs as a unit rather than independent layers. This reduces the risk of slippage between the surfaces, reducing the severity of road distresses. This, in turn, increases the service life of the surface. Bond coating is also used in patching applications where priming and waterproofing are required.
