Mastic asphalt has been used as a structural damp-proof for over 100 years.
A lot of the pavements and staircases in and around London and home counties are covered in asphalt. Mastic asphalt is a great product as it is totally seamless and can be formed around almost any shape. As an upstand detail against a building the asphalt is tucked into the chase line or terminated with render or a separating flashing with 150mm in heights. The height will allow for ‘splash back’, this happens when the rain hits the floor and can create a damp spread up the wall.
The colour of the asphalt once the sun has bleached and drawn the bitumen out of the mastic asphalt, it will turn grey in colour, this colour change blends in with a lot of the buildings and creates a ‘heritage’ look.
As a product asphalt will create a high-level damp course that will last in excess of 20 years; the product is a lot more robust than a lot of other products on the market as this product has over 100 years of tested service.

“I found Heritage Asphalt by accident on the Internet. It was a video about asphalting steps. I called Ryun who was very professional and had a great deal of experience and knowledge. The job was booked in straightaway and a team set about taking off old asphalt rebuilding and repairing the big Victorian staircase and then asphalting. The finish was quite amazing, these guys are very skillful at what they do and My husband and I were delighted. They were a professional team really hard working and highly recommend them.” Customer in London

“Ryan and team arrived, late afternoon, as agreed, to review balcony, approx. 25m2, 3 sides fed by tiled roof and one long length hand-rail. Problem, 3 leaks in different places from 10yr old asphalt roof. We discussed the problem and Ryun suggested a choice of two plan of action. We found his quotation very acceptable. This work was completed as agreed, in only a few days, to our complete satisfaction. Eight months after completion, I can now report that after a very wet winter, the roof is in a sound state. An excellent job done.” Customer in Cambridge
