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.

Delivery to Greenford: what helps

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

• If the site is up a shared drive or behind other houses, tell us the distance from the road.
• In summer Greenford gets around 16h 39m of daylight, but early deliveries still beat the traffic and give the longest working day.
• Mention any overhead cables, low branches or narrow gateways, because they decide whether a crane offload is possible.

How much will you need?

An extension in Greenford with 32 m of cavity wall needs DPC in both leaves: about 3 rolls in 30 m lengths once laps are allowed for. A 30 m² floor slab needs about 34.5 m² of DPM including laps, which is 1 roll of 4 × 25 m sheeting.

Your questions answered

Is there a minimum order for delivery to Greenford?

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 Greenford 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.

Where does the DPC go?

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