Benefits of Asphalt Steps

Asphalt is a durable and flexible material commonly used for flat roofing systems, but it is also a very popular choice for exterior steps. Asphalt steps in London provide a finish that is smooth, non-slip and waterproof. Correctly applied, asphalt steps will stand the test of time, lasting for up to 30 years.


Treads are formed in roofing-grade asphalt and laid in two coats to a thickness of 25mm, the first coat being 10mm thick and the second coat being 15mm thick incorporating 10% to 15% of additional 3mm coarse aggregate, excluding a separating membrane.


Risers are formed in roofing-grade asphalt and applied in two coats to a thickness of 13mm, completed prior to laying treads.


Strings are formed in roofing-grade asphalt and applied in two coats to a thickness of 13mm, dressed into a continual 25mm x 25mm chase, constructed either parallel to the pitch of the stairs or stepped vertically and horizontally to follow the line of the treads and risers. Strings over 300mm high to be applied in three coats to a thickness of 20mm.
