A quick quantity check

Picking the right product

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.

Getting damp proofing onto your Warrington site

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

• Mention any overhead cables, low branches or narrow gateways, because they decide whether a crane offload is possible.
• Deliveries are to the kerb, drive or within crane reach; ask if materials need to go further.
• If the drop point is block paving or soft ground, say so; heavy pallets and bulk bags can mark or sink.

Questions about damp proofing delivery in Warrington

Is there a minimum order for delivery to Warrington?

There is no fixed minimum. For very small orders we will tell you honestly if the delivery cost outweighs the materials, so you can decide.

Do you supply cavity trays?

Yes, with stop ends and weep vents for openings and abutments.

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

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 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.
