Mastic asphalt is a traditional material for a whole range of construction applications, both new build and refurbishment, applications where a smooth, seamless, durable surface is required.It offers total waterproofing integrity for roofing and tanking. It also acts as a tough working surface in flooring and paving applications.Mastic asphalt is one of the worlds most traditional construction materials and has continued to develop with the times, even in todays 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.Todays modern mastic asphalt contains highly advanced polymer formulations, pioneered by manufacturers like Permanite in the 1980s.Please note, this is an internal flooring grade.
