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.

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.

Quantities: a worked example

An extension in Haverfordwest with 32 m of cavity wall needs DPC in both leaves: about 3 rolls in 30 m lengths once laps are allowed for. A 20 m² floor slab needs about 23 m² of DPM including laps, which is 1 roll of 4 × 25 m sheeting.

Delivery to Haverfordwest: what helps

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

• If the drop point is block paving or soft ground, say so; heavy pallets and bulk bags can mark or sink.
• Keep cement, plaster and boards dry: have a tarpaulin or a garage space ready before they arrive.
• For a phased build we can split the order so materials arrive as each stage starts, which keeps the site clear.

Ordering damp proofing for Haverfordwest: FAQs

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

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.

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.

How soon can damp proofing be delivered in Haverfordwest?

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.
