Is Asphalt a DPM (Damp Proof Membrane)?

Mastic asphalt is a DPM (damp proof membrane). It has been successfully used as a damp proofing membrane for over 100 years. Some of the buildings which this historic material has protected include iconic landmarks such as ‘The Tower of London’, ‘Buckingham Palace’ and ‘Canterbury Cathedral’.

What makes mastic asphalt an especially attractive damp proofing membrane is it is totally seamless and can form around the most complex of details such as soil vent pipes, plant machines and stair balustrades. Additionally, it is carbon zero rated and 100% recyclable. This makes mastic asphalt an environmentally friendly damp proofing membrane.
