Working out quantities for your Gwent job

An extension in Gwent with 20 m of cavity wall needs DPC in both leaves: about 2 rolls 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.

Planning the drop in Gwent

Rolls are light enough to travel with a mixed load and are handed off at the kerb. Our standard mainland delivery area covers Gwent.

• Keep cement, plaster and boards dry: have a tarpaulin or a garage space ready before they arrive.
• Have someone on site for the delivery if you can, or agree a safe drop point with us in advance.
• Tell us the best drop point, such as a driveway, front garden or the kerb, and whether a lorry can park close to it.

Choosing damp proofing

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.

Your questions answered

Is there a minimum order for delivery to Gwent?

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.

Can I add other materials to my Gwent 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.

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.
