Working out quantities for your South Glamorgan job
An extension in South Glamorgan with 36 m of cavity wall needs DPC in both leaves: about 3 rolls in 30 m lengths once laps are allowed for. A 15 m² floor slab needs about 17.2 m² of DPM including laps, which is 1 roll of 4 × 25 m sheeting.
Getting damp proofing onto your South Glamorgan site
Rolls are light enough to travel with a mixed load and are handed off at the kerb. Our standard mainland delivery area covers South Glamorgan.
- Weight limits on bridges or private roads near the site matter for larger lorries, so mention any you know of.
- If the drop point is block paving or soft ground, say so; heavy pallets and bulk bags can mark or sink.
- For a phased build we can split the order so materials arrive as each stage starts, which keeps the site clear.
Choosing damp proofing
Laps and joints
DPM and DPC need generous laps and sealed joints; follow the manufacturer's guidance.
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.
Common questions from South Glamorgan
Can you deliver damp proofing to a site with restricted access in South 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.
Do you supply cavity trays?
Yes, with stop ends and weep vents for openings and abutments.
How soon can damp proofing be delivered in South Glamorgan?
We confirm the delivery date when we price your order, before you commit. It depends on the product, the quantity and whether it is a stock line or made to order.
