Mastic Asphalt roofing Portsmouth

Mastic asphalt is widely used in construction as an ideal material for a whole range of different applications, where a smooth, durable surface is required it offers waterproofing integrity for roofing applications.

Mastic Asphalt consists of carefully selected limestone aggregates which are bound together with asphaltic cement to produce a dense material which cannot be compacted, and is spread by a hand float, rather than being rolled out. It also contains highly advanced polymer formulations which in the last 5 years resulted in UK Mastic asphalt becoming the first industry in the world to achieve the Carbon Zero standard.

Mastic asphalt is one of the most traditional methods of flat roofing and needs to be installed in the right situation by correctly trained installers. Mastic asphalt is laid hot to form a seamless roofing membrane laid to minimum thickness of 20mm on top of a separating tissue where it can be shaped & moulded to fit the most awkward details and shapes.
