Sizing your order

An extension in Powys with 32 m of cavity wall needs DPC in both leaves: about 3 rolls in 30 m lengths once laps are allowed for. A 40 m² floor slab needs about 46 m² of DPM including laps, which is 1 roll of 4 × 25 m sheeting.

Delivering damp proofing in Powys

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

• For a phased build we can split the order so materials arrive as each stage starts, which keeps the site clear.
• Tell us the best drop point, such as a driveway, front garden or the kerb, and whether a lorry can park close to it.
• If the drop point is block paving or soft ground, say so; heavy pallets and bulk bags can mark or sink.

Damp Proofing & Membranes: choosing well

Laps and joints

DPM and DPC need generous laps and sealed joints; follow the manufacturer's guidance.

DPC width

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

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

Where does the DPC go?

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

Is there a minimum order for delivery to Powys?

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 Powys 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.

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.
