Mastic Asphalt is a hot laid, seamless flat roofing application that is mouldable to almost any surface. Applied correctly it can withstand weather, pedestrian traffic and vehicle movement/weight. 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 1980's. It can outlast other products many times over and is totally flame free at point of work, thus eliminating all fire risks.
