The Mastic Asphalt Council (MAC) is the trade association for the UK mastic asphalt industry. MAC represents more than 90 companies - including mastic asphalt manufacturers, the contractors responsible for its installation, and associated suppliers of equipment and services.

Top quality products, design and workmanship are fundamental to the Mastic Asphalt Council. MAC membership is only open to those manufacturers and contractors that can satisfy the stringent quality requirements. Only MAC members can use the MAC logo as a mark of quality and all mastic asphalt sold in the UK by MAC’s manufacturing members is produced in the UK and not imported.

Why Specify Mastic Asphalt?

Mastic asphalt offers total waterproofing integrity for roofing and tanking, acts as a tough working surface and damp-proof membrane in flooring and is ideal for paving, offering a durable wearing surface. Find out more here.

Mastic Asphalt for Heritage Applications

The heritage market is a key sector for the industry and mastic asphalt is frequently specified by the National Trust and English Heritage, as well as other public and private owners of prestigious buildings for refurbishment projects.

Buckingham Palace is testament to the longevity of mastic asphalt. On top of the Royal household is a rooftop of mastic asphalt that has kept the building dry for well over 80 years. Mastic asphalt was also first laid on the Stone Gallery of London’s St Paul’s Cathedral in 1906 and it provided a remarkable 111 years’ weatherproof protection before it required refurbishment.
