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.

Getting damp proofing onto your Blyth site

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

• Have someone on site for the delivery if you can, or agree a safe drop point with us in advance.
• If the site is up a shared drive or behind other houses, tell us the distance from the road.
• If neighbours share the access, it helps to let them know a lorry is coming.

How much will you need?

An extension in Blyth with 28 m of cavity wall needs DPC in both leaves: about 3 rolls in 30 m lengths once laps are allowed for. A 25 m² floor slab needs about 28.7 m² of DPM including laps, which is 1 roll of 4 × 25 m sheeting.

Your questions answered

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

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.

What is the difference between DPC and DPM?

DPC is a strip built into walls to stop damp rising through the masonry. DPM is a sheet laid under a concrete floor slab. They are lapped together so there is no gap.

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

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.
