Quantities: a worked example

An extension in Truro with 24 m of cavity wall needs DPC in both leaves: about 2 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.

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

• On busy streets in Truro, a parking suspension or a quiet time slot can make offloading safer, so tell us about local restrictions you know of.
• Clear a level area for pallets, ideally on boards, so materials stay out of standing water.
• Pallets left on a pavement can block the footway, so plan a drop point inside your boundary where you can.

Picking the right product

Laps and joints

DPM and DPC need generous laps and sealed joints; follow the manufacturer's guidance.

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.
