Fast becoming the material of choice for schools and universities, mastic asphalt – one of the world’s most durable waterproofing materials – is seeing a renaissance as more and more specifiers look again at what can now be regarded as one of the greenest construction materials in the UK.

Such is the reliability and integrity of mastic asphalt that many architects specifying waterproofing membranes for schools make it their preferred choice. Tough enough to take a green roof design, mastic asphalt enquiries are up by more than 50% year on year.

Chosen for its environmental credentials and good looks, a green roof system laid with a mastic asphalt waterproofing system, enhances the environment, controls storm water run-off and reduces noise and heat transmissions by upgrading the acoustic and thermal performance of a roof.

Using mastic asphalt eliminates the need for root barriers, which would have been necessary had an alternative material been used. Lesser membranes to mastic asphalt are more prone to site damage leading to potentially catastrophic and expensive leaks. So it is no wonder that mastic asphalt is being positively encouraged as THE solution to all green roof and other waterproofing applications. In the unlikely event of a failure, its seamless structure means it can easily be spot repaired, eliminating the need for costly wholesale replacement.

Mastic asphalt offers a watertight guarantee that your roof will perform. The Mastic Asphalt Council (MAC) ensures that every installer of mastic asphalt has trained and achieved an NVQ level 2 or level 3 in the mastic asphalt craft. This means that anyone looking for an asphalt roof can be sure that it will only be applied by reputable and skilled craftsman. The manufacturers of mastic asphalt are all accredited to ISO:9001 and ISO:14001, the industry standard marks of Quality and Environmental Management.
