Rolls are light enough to travel with a mixed load and are handed off at the kerb. Ewell 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.
• Give us the full postcode for the drop point; deliveries around KT17 are priced to the exact address.
• On busy streets in Ewell, a parking suspension or a quiet time slot can make offloading safer, so tell us about local restrictions you know of.

A quick quantity check

An extension in Ewell 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.

Damp Proofing & Membranes: choosing well

DPC width

Match the DPC width to the wall leaf so it runs the full width of the masonry.

Is radon protection needed?

Parts of the UK need radon protection in new buildings and extensions. UKHSA radon maps show the areas; building control will tell you what applies.

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.
