A damp proof course is essential for protecting your building from rising moisture, which can cause structural damage, mould growth, and deterioration of internal finishes. DPC membrane creates a reliable barrier within walls, preventing ground moisture from travelling upwards through masonry and compromising the integrity of your construction.
McMahons stocks high-performance damp proofing solutions suitable for new builds, extensions, and remedial work.

Selecting the correct membrane depends on your wall type and application point. Standard 450mm width suits most residential ground floor installations, while wider rolls work better for retaining walls and below-ground applications. Consider thickness and flexibility when working with uneven surfaces or complex junctions where the material needs to conform without puncturing.
