Mastic asphalt is an ideal material for a whole range of construction applications, both new build and refurbishment, where a smooth, seamless, durable surface is required.
It offers total waterproofing integrity for roofing and tanking and acts as a tough
working surface in flooring and paving. Mastic asphalt is one of the world’s most
traditional construction materials and has continued to develop with the times, even in today’s hi-tech building industry.
The product comprises suitably graded limestone aggregates bound together with an asphaltic cement (primarily refined bitumens) to produce a dense, voidless material. It cannot be compacted, and is spread by means of a hand float, rather than rolled. Today’s modern mastic asphalt contains highly advanced polymer formulations, pioneered by manufacturers like Permanite in the 1980s.
Mastic asphalt, such as Permaphalt, is installed by trained operatives who have
undertaken extensive training programmes. In 2008 UK Mastic asphalt became the first industry in the world to achieve the CarbonZero standard.
