A quick quantity check

Getting the right damp proofing

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.

How delivery works in Billericay

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

• Give us the full postcode for the drop point; deliveries around CM11 are priced to the exact address.
• Clear a level area for pallets, ideally on boards, so materials stay out of standing water.
• On busy streets in Billericay, a parking suspension or a quiet time slot can make offloading safer, so tell us about local restrictions you know of.
