Before you order damp proofing

Laps and joints

DPM and DPC need generous laps and sealed joints; follow the manufacturer's guidance.

DPC width

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

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 Gainsborough delivery arrives

Rolls are light enough to travel with a mixed load and are handed off at the kerb. Gainsborough 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.
• Give us the full postcode for the drop point; deliveries around DN21 are priced to the exact address.
• Mention any overhead cables, low branches or narrow gateways, because they decide whether a crane offload is possible.

Estimating your damp proofing

An extension in Gainsborough with 36 m of cavity wall needs DPC in both leaves: about 3 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.
