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.

DPC width

Match the DPC width to the wall leaf so it runs the full width of the masonry.

Wales has its own Approved Documents, including its own Part L for energy efficiency, and building control is handled by the local authority or a registered approver.

Estimating your damp proofing

An extension in Welshpool with 28 m of cavity wall needs DPC in both leaves: about 3 rolls in 30 m lengths once laps are allowed for. A 40 m² floor slab needs about 46 m² of DPM including laps, which is 1 roll of 4 × 25 m sheeting.

Delivering damp proofing in Welshpool

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

• Deliveries are to the kerb, drive or within crane reach; ask if materials need to go further.
• If neighbours share the access, it helps to let them know a lorry is coming.
• Weight limits on bridges or private roads near the site matter for larger lorries, so mention any you know of.
