Sizing your order

An extension in North Yorkshire 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 North Yorkshire

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

• Give us the full postcode for the drop point; deliveries around YO are priced to the exact address.
• If the site is up a shared drive or behind other houses, tell us the distance from the road.
• Have someone on site for the delivery if you can, or agree a safe drop point with us in advance.

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

Where does the DPC go?

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

There is no fixed minimum. For very small orders we will tell you honestly if the delivery cost outweighs the materials, so you can decide.
