Damp proof membrane is a membrane material that is applied within a roof, wall, or under flooring to prevent any moisture from getting in. Our damp proof membrane is made of a polythene material, which is the most commonly used material for this type of job. It is usually required when using certain insulation materials such as, mineral wool or cellulose, to protect the insulation and prevent damp.

It can also be used for such as, poorly ventilated kitchens and bathrooms, as well as for external walls, or creating a waterproof layer under a floor, or slabs.
