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.

Estimating your damp proofing

An extension in Whitefield with 36 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.

Delivering damp proofing in Whitefield

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

• Weight limits on bridges or private roads near the site matter for larger lorries, so mention any you know of.
• Clear a level area for pallets, ideally on boards, so materials stay out of standing water.
• Have someone on site for the delivery if you can, or agree a safe drop point with us in advance.
