Estimating your damp proofing

An extension in Birkenhead with 24 m of cavity wall needs DPC in both leaves: about 2 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 Birkenhead

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

• On busy streets in Birkenhead, a parking suspension or a quiet time slot can make offloading safer, so tell us about local restrictions you know of.
• If the site is up a shared drive or behind other houses, tell us the distance from the road.
• 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

Laps and joints

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

DPC width

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

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 Birkenhead?

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.

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 Birkenhead?

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

Where does the DPC go?

Usually at least 150 mm above outside ground level, linked to the floor DPM.
