Mastic asphalt can be applied to form a continuous waterproof covering over flat, sloped or curved surfaces and can be worked round pipes, roof lights and other projections.
It can be laid on most types of rigid sub-structure such as concrete, pre-cast concrete deck units, timber boarding, metal decking and other proprietary decking units. Thermal insulation materials can easily be laid as part of a mastic asphalt specification to give any required U-value. Treatments applied to asphalt can provide a surface suitable for traffic, increase solar reflectivity and provide a decorative finish.
Mastic asphalt is traditionally recognised as one of the best and most durable waterproofing membranes. The development of polymer-modified asphalt applied in accordance with the correct design detailing will ensure many years of maintenance-free life.
