Damp Proofing & Membranes delivered to Brecon
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.
Trades and homeowners in Brecon can order damp proofing for delivery by sending a list, a drawing or just the sizes of the job.

What damp proofing can we deliver to Brecon?
- DPC rollsPolymer and bitumen damp-proof course in standard wall widths.
- Cavity trays and stop endsTo direct water out of the cavity over openings.
- Radon barriersGas-resistant membranes for areas that need radon protection.
- Weep ventsFor drainage and ventilation at the base of cavities and over trays.

How much will you need?
An extension in Brecon with 24 m of cavity wall needs DPC in both leaves: about 2 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.
Picking the right product
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.
Delivery to Brecon: what helps
Rolls are light enough to travel with a mixed load and are handed off at the kerb. Brecon is inside our standard mainland delivery area.
- Weight limits on bridges or private roads near the site matter for larger lorries, so mention any you know of.
- Mention any overhead cables, low branches or narrow gateways, because they decide whether a crane offload is possible.
- Clear a level area for pallets, ideally on boards, so materials stay out of standing water.
Damp Proofing & Membranes questions
Can you deliver damp proofing to a site with restricted access in Brecon?
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 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.
Is there a minimum order for delivery to Brecon?
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.
