Damp Proofing & Membranes for sites in Bedfordshire
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 price damp proofing for jobs anywhere in Bedfordshire; send a list or the sizes of the job and we will quote it delivered.

How much will you need?
An extension in Bedfordshire with 36 m of cavity wall needs DPC in both leaves: about 3 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.
Delivery to Bedfordshire: what helps
Rolls are light enough to travel with a mixed load and are handed off at the kerb. Our standard mainland delivery area covers Bedfordshire.
- Keep cement, plaster and boards dry: have a tarpaulin or a garage space ready before they arrive.
- Have someone on site for the delivery if you can, or agree a safe drop point with us in advance.
- Clear a level area for pallets, ideally on boards, so materials stay out of standing water.
Choosing damp proofing
DPC width
Match the DPC width to the wall leaf so it runs the full width of the masonry.
Laps and joints
DPM and DPC need generous laps and sealed joints; follow the manufacturer's guidance.
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.
Ordering damp proofing for Bedfordshire: FAQs
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.
Can you deliver damp proofing to a site with restricted access in Bedfordshire?
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.
Can I add other materials to my Bedfordshire 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.
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.
