Damp Proofing & Membranes: choosing well

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.

Before your Christchurch delivery arrives

Rolls are light enough to travel with a mixed load and are handed off at the kerb. Christchurch 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.
• If the drop point is block paving or soft ground, say so; heavy pallets and bulk bags can mark or sink.
• Mention any overhead cables, low branches or narrow gateways, because they decide whether a crane offload is possible.

Questions about damp proofing delivery in Christchurch

Do you supply cavity trays?

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

How soon can damp proofing be delivered in Christchurch?

We confirm the delivery date when we price your order, before you commit. It depends on the product, the quantity and whether it is a stock line or made to order.

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

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

What is the difference between DPC and DPM?

DPC is a strip built into walls to stop damp rising through the masonry. DPM is a sheet laid under a concrete floor slab. They are lapped together so there is no gap.
