Damp proofing is required for a large variety of structural applications. When pouring concrete floors damp proof membrane (DPM) must be laid to prevent any rising damp from causing issues with the concrete. DPM comes in differing specifications for different needs, such as for use as a radon barrier when building on gas contaminated land. Damp proof course (DPC) prevents moisture rising from the ground and damaging your property. This excess moisture can affect plaster, decoration and can even result in wet rot, or dry rot affecting unprotected timbers. Our range of DPM and DPC is available to buy now for collection and delivery across Belfast & Northern Ireland.
