Damp Proofing & Membranes delivered to Windsor
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 Windsor, from a single pallet for a small job to full loads for bigger builds.

Quantities: a worked example
An extension in Windsor with 16 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.
Before you order 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.

Rolls are light enough to travel with a mixed load and are handed off at the kerb. Windsor is inside our standard mainland delivery area.
- Clear a level area for pallets, ideally on boards, so materials stay out of standing water.
- With roughly 7h 50m of daylight in Windsor around the shortest day, morning deliveries leave more working light for the job.
