Choosing 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.

Wales has its own Approved Documents, including its own Part L for energy efficiency, and building control is handled by the local authority or a registered approver.

Getting damp proofing onto your Bridgend site

Rolls are light enough to travel with a mixed load and are handed off at the kerb. Bridgend 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.
• Pallets left on a pavement can block the footway, so plan a drop point inside your boundary where you can.
• Give us the full postcode for the drop point; deliveries around CF31 are priced to the exact address.

Quantities: a worked example

An extension in Bridgend with 20 m of cavity wall needs DPC in both leaves: about 2 rolls in 30 m lengths once laps are allowed for. A 30 m² floor slab needs about 34.5 m² of DPM including laps, which is 1 roll of 4 × 25 m sheeting.

Your questions answered

Is there a minimum order for delivery to Bridgend?

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.

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.

How soon can damp proofing be delivered in Bridgend?

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.
