Rolls are light enough to travel with a mixed load and are handed off at the kerb. Maesteg 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.
• Keep cement, plaster and boards dry: have a tarpaulin or a garage space ready before they arrive.
• Mention any overhead cables, low branches or narrow gateways, because they decide whether a crane offload is possible.

Before you order damp proofing

DPC width

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

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.

Damp Proofing & Membranes questions

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.

What is the difference between DPC and DPM?

DPC is a strip built into walls to stop damp rising through the masonry. DPM is a sheet laid under a concrete floor slab. They are lapped together so there is no gap.

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

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.

Do you deliver damp proofing to trades and homeowners in Maesteg?

Both. Trades can apply for a trade account; homeowners and self-builders can order on a delivered quote.
