Damp proofing membranes protect different parts of a structure from damage arising from damp, including mould and mildew, and the risk of rotten timber.

A damp proof course 150mm above ground level can keep out rising damp that could otherwise penetrate masonry, and is an important addition when building with clay bricks and similar building supplies.

Damp proofing membrane is sometimes called DPM for short, or DPC membrane as shorthand for 'damp proof course membrane'. A damp course is not the only method of damp proofing for the home. Our range of damp proof products also includes chimney pots, which can help to keep adverse weather from entering the property via the chimney.

Jewson building materials can make sure you have everything you need to not only install a damp proof course, but to complete the job from start to finish.

If renovating after a pre-existing damp problem, consider installing fresh sawn & carcassing timber to replace rotten stud work and battens.

Our metalwork wall & frame ties are ideal for work on cavity walls, to hold everything securely together once your damp course is in place.

Whatever damp challenges you are facing, Jewson can help. Contact us via the website or in-branch and we will be happy to suggest the best building supplies for your damp course.
