Damp Proofing & Membranes: choosing well

Laps and joints

DPM and DPC need generous laps and sealed joints; follow the manufacturer's guidance.

Is radon protection needed?

Parts of the UK need radon protection in new buildings and extensions. UKHSA radon maps show the areas; the council's building standards service will tell you what applies.

In Scotland most building work needs a building warrant from the local authority, assessed against the Building Standards Technical Handbooks.

Rolls are light enough to travel with a mixed load and are handed off at the kerb. Helensburgh is inside our standard mainland delivery area.

• Weight limits on bridges or private roads near the site matter for larger lorries, so mention any you know of.
• If neighbours share the access, it helps to let them know a lorry is coming.
• If the site is up a shared drive or behind other houses, tell us the distance from the road.

A quick quantity check

An extension in Helensburgh with 32 m of cavity wall needs DPC in both leaves: about 3 rolls in 30 m lengths once laps are allowed for. A 50 m² floor slab needs about 57.5 m² of DPM including laps, which is 1 roll of 4 × 25 m sheeting.

What is the difference between DPC and DPM?

DPC is a strip built into walls to stop damp rising through the masonry. DPM is a sheet laid under a concrete floor slab. They are lapped together so there is no gap.

There is no fixed minimum. For very small orders we will tell you honestly if the delivery cost outweighs the materials, so you can decide.
