Before you order damp proofing

Laps and joints

DPM and DPC need generous laps and sealed joints; follow the manufacturer's guidance.

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 Shepherds Bush with 36 m of cavity wall needs DPC in both leaves: about 3 rolls in 30 m lengths once laps are allowed for. A 20 m² floor slab needs about 23 m² of DPM including laps, which is 1 roll of 4 × 25 m sheeting.

Delivery to Shepherds Bush: what helps

Rolls are light enough to travel with a mixed load and are handed off at the kerb. Shepherds Bush is inside our standard mainland delivery area.

• Clear a level area for pallets, ideally on boards, so materials stay out of standing water.
• Mention any overhead cables, low branches or narrow gateways, because they decide whether a crane offload is possible.
• If neighbours share the access, it helps to let them know a lorry is coming.

Damp Proofing & Membranes questions

Where does the DPC go?

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

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 Shepherds Bush 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.

Can you deliver damp proofing to a site with restricted access in Shepherds Bush?

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.
