Damp Proofing & Membranes for sites in Greater Manchester

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 Greater Manchester; send a list or the sizes of the job and we will quote it delivered.

Sizing your order

An extension in Greater Manchester with 28 m of cavity wall needs DPC in both leaves: about 3 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.

How delivery works in Greater Manchester

Rolls are light enough to travel with a mixed load and are handed off at the kerb. Our standard mainland delivery area covers Greater Manchester.

  • On busy streets in Greater Manchester, a parking suspension or a quiet time slot can make offloading safer, so tell us about local restrictions you know of.
  • Weight limits on bridges or private roads near the site matter for larger lorries, so mention any you know of.
  • If neighbours share the access, it helps to let them know a lorry is coming.

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.

Common questions from Greater Manchester

Where does the DPC go?

Usually at least 150 mm above outside ground level, linked to the floor DPM.

Is there a minimum order for delivery to Greater Manchester?

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 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.

Can I add other materials to my Greater Manchester 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.
