Estimating your damp proofing

An extension in Neath with 16 m of cavity wall needs DPC in both leaves: about 2 rolls in 30 m lengths once laps are allowed for. A 25 m² floor slab needs about 28.7 m² of DPM including laps, which is 1 roll of 4 × 25 m sheeting.

Getting damp proofing onto your Neath site

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

• With roughly 7h 48m of daylight in Neath around the shortest day, morning deliveries leave more working light for the job.
• Tell us the best drop point, such as a driveway, front garden or the kerb, and whether a lorry can park close to it.
• In summer Neath gets around 16h 40m of daylight, but early deliveries still beat the traffic and give the longest working day.

Getting the right damp proofing

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; building control will tell you what applies.

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.
