Working out quantities for your Brent job

An extension in Brent with 16 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.

Before your Brent delivery arrives

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

• If neighbours share the access, it helps to let them know a lorry is coming.
• If the drop point is block paving or soft ground, say so; heavy pallets and bulk bags can mark or sink.
• In summer Brent gets around 16h 39m of daylight, but early deliveries still beat the traffic and give the longest working day.

Choosing damp proofing

Laps and joints

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

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.

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 Brent

Do you supply cavity trays?

Yes, with stop ends and weep vents for openings and abutments.

Is there a minimum order for delivery to Brent?

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.

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

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.

Where does the DPC go?

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