Choosing damp proofing

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.

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.

Before your Chorley delivery arrives

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

• For a phased build we can split the order so materials arrive as each stage starts, which keeps the site clear.
• Pallets left on a pavement can block the footway, so plan a drop point inside your boundary where you can.
• Have someone on site for the delivery if you can, or agree a safe drop point with us in advance.
