Getting the right 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 Yeadon delivery arrives

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

• Give us the full postcode for the drop point; deliveries around LS19 are priced to the exact address.
• With roughly 7h 24m of daylight in Yeadon around the shortest day, morning deliveries leave more working light for the job.
• Mention any overhead cables, low branches or narrow gateways, because they decide whether a crane offload is possible.

Ordering damp proofing for Yeadon: FAQs

Can you deliver damp proofing to a site with restricted access in Yeadon?

Usually, yes. Tell us about the access when you ask for a price and we will plan the vehicle and offload, or say if a smaller vehicle is needed.

Do you deliver damp proofing to trades and homeowners in Yeadon?

Both. Trades can apply for a trade account; homeowners and self-builders can order on a delivered quote.

How thick should a DPM be?

1200-gauge polythene, around 300 microns, is a common specification for floor slabs. Your design may call for something different.

Do I need a radon barrier?

It depends on where you are. In radon-affected areas building control requires radon protection in new buildings and extensions.
