Damp Proofing & Membranes delivery in Northampton
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.
Whether it is a repair, an extension or a new build in Northampton, we can supply the damp proofing and deliver to site.

Getting damp proofing onto your Northampton site
Rolls are light enough to travel with a mixed load and are handed off at the kerb. Northampton is inside our standard mainland delivery area.
- Tell us the best drop point, such as a driveway, front garden or the kerb, and whether a lorry can park close to it.
- Keep cement, plaster and boards dry: have a tarpaulin or a garage space ready before they arrive.
- Clear a level area for pallets, ideally on boards, so materials stay out of standing water.
Picking the right product
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.
Quantities: a worked example
An extension in Northampton with 16 m of cavity wall needs DPC in both leaves: about 2 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.
Ordering damp proofing for Northampton: FAQs
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 Northampton?
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.
Can I add other materials to my Northampton delivery?
Yes. Put everything on one list, from damp proofing to fixings and PPE, and we will price it as one delivery where the products can travel together.
