A quick quantity check

An extension in Dover with 36 m of cavity wall needs DPC in both leaves: about 3 rolls in 30 m lengths once laps are allowed for. A 15 m² floor slab needs about 17.2 m² of DPM including laps, which is 1 roll of 4 × 25 m sheeting.

Planning the drop in Dover

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

• If neighbours share the access, it helps to let them know a lorry is coming.
• Mention any overhead cables, low branches or narrow gateways, because they decide whether a crane offload is possible.
• Weight limits on bridges or private roads near the site matter for larger lorries, so mention any you know of.

Choosing 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.

Common questions from Dover

Do I need a radon barrier?

It depends on where you are. In radon-affected areas building control requires radon protection in new buildings and extensions.

How thick should a DPM be?

1200-gauge polythene, around 300 microns, is a common specification for floor slabs. Your design may call for something different.
