A quick quantity check

An extension in Weymouth with 16 m of cavity wall needs DPC in both leaves: about 2 rolls in 30 m lengths once laps are allowed for. A 20 m² floor slab needs about 23 m² of DPM including laps, which is 1 roll of 4 × 25 m sheeting.

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.

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.

Before your Weymouth delivery arrives

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

• For a phased build we can split the order so materials arrive as each stage starts, which keeps the site clear.
• If the drop point is block paving or soft ground, say so; heavy pallets and bulk bags can mark or sink.
• In summer Weymouth gets around 16h 29m of daylight, but early deliveries still beat the traffic and give the longest working day.
