Estimating your damp proofing

An extension in West Glamorgan with 12 m of cavity wall needs DPC in both leaves: about 1 roll 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.

Delivery to West Glamorgan: what helps

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

• Keep cement, plaster and boards dry: have a tarpaulin or a garage space ready before they arrive.
• If the site is up a shared drive or behind other houses, tell us the distance from the road.
• Clear a level area for pallets, ideally on boards, so materials stay out of standing water.

Things to check before you order

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

Where does the DPC go?

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

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

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.

Is there a minimum order for delivery to West Glamorgan?

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.
