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.
Working out quantities for your Caterham job
An extension in Caterham with 20 m of cavity wall needs DPC in both leaves: about 2 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.
Before your Caterham delivery arrives
Rolls are light enough to travel with a mixed load and are handed off at the kerb. Caterham is inside our standard mainland delivery area.
- Clear a level area for pallets, ideally on boards, so materials stay out of standing water.
- With roughly 7h 52m of daylight in Caterham 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.
Common questions from Caterham
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.
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.
