Mastic Asphalt Roofing
Mastic asphalt roofing can be applied to form a continuous waterproof covering over flat, sloped or curved surfaces. It is a flexible solution that can be used to work around areas such as pipes, roof lights and other projections.
It can be laid on almost any type of rigid sub-structure such as concrete, timber and metal decking. In addition, thermal insulation materials can be easily laid as part of a mastic asphalt roofing specification to give any required U-value (the measure of how effective a material is as an insulator).
Mastic asphalt is also an ideal waterproofing material for extensive green roofs, intensive roof gardens and biodiversity roofs as it is completely resistant to root penetration and does not require an additional anti-root barrier. As a waterproofing membrane it is not affected by water so will not rot or decay. It has a long and proven track record and has been used successfully on many green roof projects.
