Things to check before you order

DPC width

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.

Before your Willesden delivery arrives

Rolls are light enough to travel with a mixed load and are handed off at the kerb. Willesden 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.
• Deliveries are to the kerb, drive or within crane reach; ask if materials need to go further.
• Weight limits on bridges or private roads near the site matter for larger lorries, so mention any you know of.

How much will you need?

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