Estimating your damp proofing

An extension in Huntingdon with 28 m of cavity wall needs DPC in both leaves: about 3 rolls in 30 m lengths once laps are allowed for. A 30 m² floor slab needs about 34.5 m² of DPM including laps, which is 1 roll of 4 × 25 m sheeting.

How delivery works in Huntingdon

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

• If the site is up a shared drive or behind other houses, tell us the distance from the road.
• If the drop point is block paving or soft ground, say so; heavy pallets and bulk bags can mark or sink.
• Clear a level area for pallets, ideally on boards, so materials stay out of standing water.

Choosing damp proofing

DPC width

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

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.
