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.

Sizing your order

An extension in Retford with 20 m of cavity wall needs DPC in both leaves: about 2 rolls in 30 m lengths once laps are allowed for. A 15 m² floor slab needs about 17.2 m² of DPM including laps, which is 1 roll of 4 × 25 m sheeting.

• If neighbours share the access, it helps to let them know a lorry is coming.
• In summer Retford gets around 17h 00m of daylight, but early deliveries still beat the traffic and give the longest working day.
• Have someone on site for the delivery if you can, or agree a safe drop point with us in advance.
