Choosing damp proofing

Is radon protection needed?

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

Laps and joints

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

In England, building work is checked against the Approved Documents, for example Part A for structure and Part L for energy efficiency, through your council's building control team or a registered building control approver.

How much will you need?

An extension in Royal Leamington Spa with 28 m of cavity wall needs DPC in both leaves: about 3 rolls in 30 m lengths once laps are allowed for. A 15 m² floor slab needs about 17.2 m² of DPM including laps, which is 1 roll of 4 × 25 m sheeting.

Common questions from Royal Leamington Spa

Do you supply cavity trays?

Yes, with stop ends and weep vents for openings and abutments.

How thick should a DPM be?
