Polymer Modified Asphalt
Why Asphalt?
Mastic asphalt is the ultimate protection for a wide range of construction applications. Its seamless nature offers total waterproofing integrity for roofing and tanking applications.
Whilst it is one of the world’s most traditional construction materials, it has continued to develop with the times and even in today’s fast-track building industry Polymer Modified Mastic Asphalt remains the unrivalled choice for many designers and specifers. The addition of SBS (Styrene Butadine Styrene) Polymers to the bitumen binder gives an increased tolerance to building movement, climatic extremes and thermal shock.
