Estimating your damp proofing

An extension in Worcestershire with 28 m of cavity wall needs DPC in both leaves: about 3 rolls 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.

Planning the drop in Worcestershire

Rolls are light enough to travel with a mixed load and are handed off at the kerb. Our standard mainland delivery area covers Worcestershire.

• On busy streets in Worcestershire, a parking suspension or a quiet time slot can make offloading safer, so tell us about local restrictions you know of.
• If neighbours share the access, it helps to let them know a lorry is coming.
• For a phased build we can split the order so materials arrive as each stage starts, which keeps the site clear.

Getting the right damp proofing

DPC width

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

Is radon protection needed?

Parts of the UK need radon protection in new buildings and extensions. UKHSA radon maps show the areas; building control will tell you what applies.

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.

Your questions answered

Can you deliver damp proofing to a site with restricted access in Worcestershire?

Usually, yes. Tell us about the access when you ask for a price and we will plan the vehicle and offload, or say if a smaller vehicle is needed.

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.

Do you deliver damp proofing to trades and homeowners in Worcestershire?

Both. Trades can apply for a trade account; homeowners and self-builders can order on a delivered quote.
