Building Materials
Damp Proofing & Membranes for sites in Durham
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.
Builders, trades and self-builders in Durham can order damp proofing for delivery to Darlington, Peterlee and the towns in between.

Estimating your damp proofing
An extension in Durham with 20 m of cavity wall needs DPC in both leaves: about 2 rolls in 30 m lengths once laps are allowed for. A 40 m² floor slab needs about 46 m² of DPM including laps, which is 1 roll of 4 × 25 m sheeting.
Planning the drop in Durham
Rolls are light enough to travel with a mixed load and are handed off at the kerb. Our standard mainland delivery area covers Durham.
- If the drop point is block paving or soft ground, say so; heavy pallets and bulk bags can mark or sink.
- On busy streets in Durham, a parking suspension or a quiet time slot can make offloading safer, so tell us about local restrictions you know of.
- Pallets left on a pavement can block the footway, so plan a drop point inside your boundary where you can.
Before you order damp proofing
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.
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.
