Picking the right product

DPC width

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

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.

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.

Before your Cwmbran delivery arrives

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

Quantities: a worked example

An extension in Cwmbran with 12 m of cavity wall needs DPC in both leaves: about 1 roll in 30 m lengths once laps are allowed for. A 50 m² floor slab needs about 57.5 m² of DPM including laps, which is 1 roll of 4 × 25 m sheeting.

Damp Proofing & Membranes questions

Is there a minimum order for delivery to Cwmbran?

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 I add other materials to my Cwmbran delivery?

Yes. Put everything on one list, from damp proofing to fixings and PPE, and we will price it as one delivery where the products can travel together.

Where does the DPC go?

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