Building Materials
Damp Proofing & Membranes delivered to Trowbridge
Damp proofing materials stop moisture rising or passing through a building: a damp-proof course (DPC) in the walls and a damp-proof membrane (DPM) under the floor.
We deliver damp proofing to sites, driveways and yards across Trowbridge, from a single pallet for a small job to full loads for bigger builds.

Planning the drop in Trowbridge
Rolls are light enough to travel with a mixed load and are handed off at the kerb. Trowbridge is inside our standard mainland delivery area.
- 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.
- Mention any overhead cables, low branches or narrow gateways, because they decide whether a crane offload is possible.
Picking the right product
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.
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.
Sizing your order
An extension in Trowbridge with 28 m of cavity wall needs DPC in both leaves: about 3 rolls in 30 m lengths once laps are allowed for. A 50 m² floor slab needs about 57.5 m² of DPM including laps, which is 1 roll of 4 × 25 m sheeting.
Damp Proofing & Membranes in Trowbridge: questions
How soon can damp proofing be delivered in Trowbridge?
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.
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.
Where does the DPC go?
Usually at least 150 mm above outside ground level, linked to the floor DPM.
Is there a minimum order for delivery to Trowbridge?
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.
