Before you order 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 Redhill with 36 m of cavity wall needs DPC in both leaves: about 3 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.

How delivery works in Redhill

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

• Give us the full postcode for the drop point; deliveries around RH1 are priced to the exact address.
• If the drop point is block paving or soft ground, say so; heavy pallets and bulk bags can mark or sink.
• Pallets left on a pavement can block the footway, so plan a drop point inside your boundary where you can.
