Mastic asphalt is used for waterproofing and tanking a number of different applications. These applications include flat roof, steps, flooring. walkways, basements, balconies and car parks. The type of mastic asphalt used will vary between applications. Car parks and roofs serving as loading bays endure heavier traffic so will need extra grit added to provide a harder finish.
Mastic asphalt is known as 'The King Of Waterproofing'. It is made up of limestone aggregates bound together with either bitumen or modified bitumen. Some forms of asphalt will contain Lake Asphalt from the famous lake in Trinidad discovered by Sir Walter Raleigh. Once bound mastic asphalt is dense and seamless with no voids. This makes it a perfect material for waterproofing a range of substrates.
An asphalt flat roof is one of the first things which comes to mind when someone mentions mastic asphalt. Asphalt roofs can be found all over London. Nowadays a lot of these roofs will have been overlaid with felt or a liquid roofing system. Mastic asphalt roofing is normally laid in 2 coats of roofing grade mastic asphalt (R988). The first coat of the asphalt is laid on to sheathing felt to allow movement between the substrate and the membrane. The final coat of mastic asphalt is normally painted in two coats of solar reflective paint to maximise the longevity of the roof. Mastic asphalt is a great choice for flat roofs as it provides a seamless finish, a long lifespan, a carbon zero rating and the ability to be repaired in almost all cases.
