A quick quantity check
An extension in West Midlands with 20 m of cavity wall needs DPC in both leaves: about 2 rolls in 30 m lengths once laps are allowed for. A 25 m² floor slab needs about 28.7 m² of DPM including laps, which is 1 roll of 4 × 25 m sheeting.
How delivery works in West Midlands
Rolls are light enough to travel with a mixed load and are handed off at the kerb. Our standard mainland delivery area covers West Midlands.
- For a phased build we can split the order so materials arrive as each stage starts, which keeps the site clear.
- If neighbours share the access, it helps to let them know a lorry is coming.
- Pallets left on a pavement can block the footway, so plan a drop point inside your boundary where you can.
Things to check before you order
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.
DPC width
Match the DPC width to the wall leaf so it runs the full width of the masonry.
In England, building work is checked against the Approved Documents, for example Part A for structure and Part L for energy efficiency, through your council's building control team or a registered building control approver.
Your questions answered
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.
How soon can damp proofing be delivered in West Midlands?
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.
Is there a minimum order for delivery to West Midlands?
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.
Do you supply cavity trays?
Yes, with stop ends and weep vents for openings and abutments.
