Roof Systems

Polymer Modified 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.

Polymer Modified Mastic Asphalt is installed by trained operatives who have undertaken the mastic asphalt industry’s extensive training programme, which lasts for a minimum of 3 years to NVQ level 2/3 or equivalent. Polymer Modified Mastic Asphalt can only be installed by listed contractors. As a result we can offer comprehensive guarantees with complete confidence in both labour and materials.
