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.

A quick quantity check

An extension in Bishop Auckland with 24 m of cavity wall needs DPC in both leaves: about 2 rolls in 30 m lengths once laps are allowed for. A 50 m² floor slab needs about 57.5 m² of DPM including laps, which is 1 roll of 4 × 25 m sheeting.

Before your Bishop Auckland delivery arrives

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

• Weight limits on bridges or private roads near the site matter for larger lorries, so mention any you know of.
• Mention any overhead cables, low branches or narrow gateways, because they decide whether a crane offload is possible.
• Give us the full postcode for the drop point; deliveries around DL14 are priced to the exact address.

Damp Proofing & Membranes questions

Where does the DPC go?

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

Can I add other materials to my Bishop Auckland delivery?

Yes. Put everything on one list, from damp proofing to fixings and PPE, and we will price it as one delivery where the products can travel together.

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

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.
