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.

DPC width

Match the DPC width to the wall leaf so it runs the full width of the masonry.

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.

Working out quantities for your Smethwick job

An extension in Smethwick with 24 m of cavity wall needs DPC in both leaves: about 2 rolls in 30 m lengths once laps are allowed for. A 25 m² floor slab needs about 28.7 m² of DPM including laps, which is 1 roll of 4 × 25 m sheeting.

How delivery works in Smethwick

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

• If the site is up a shared drive or behind other houses, tell us the distance from the road.
• If neighbours share the access, it helps to let them know a lorry is coming.
• For a phased build we can split the order so materials arrive as each stage starts, which keeps the site clear.

Common questions from Smethwick

How soon can damp proofing be delivered in Smethwick?

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 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.

Where does the DPC go?

Usually at least 150 mm above outside ground level, linked to the floor DPM.

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

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