Working out quantities for your Mid Glamorgan job

An extension in Mid Glamorgan 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.

Planning the drop in Mid Glamorgan

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

• Keep cement, plaster and boards dry: have a tarpaulin or a garage space ready before they arrive.
• Give us the full postcode for the drop point; deliveries around CF are priced to the exact address.
• Mention any overhead cables, low branches or narrow gateways, because they decide whether a crane offload is possible.

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.

Damp Proofing & Membranes questions

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.

Do you deliver damp proofing to trades and homeowners in Mid Glamorgan?

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

Can you deliver damp proofing to a site with restricted access in Mid 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.

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.
