Getting the right damp proofing

DPC width

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

Laps and joints

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

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.

Quantities: a worked example

An extension in Wellington with 12 m of cavity wall needs DPC in both leaves: about 1 roll 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.

Delivery to Wellington: what helps

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

• With roughly 7h 37m of daylight in Wellington around the shortest day, morning deliveries leave more working light for the job.
• Keep cement, plaster and boards dry: have a tarpaulin or a garage space ready before they arrive.
• If the site is up a shared drive or behind other houses, tell us the distance from the road.
