A quick quantity check

An extension in Crowthorne with 16 m of cavity wall needs DPC in both leaves: about 2 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.

Getting the right 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.

Getting damp proofing onto your Crowthorne site

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

• With roughly 7h 51m of daylight in Crowthorne around the shortest day, morning deliveries leave more working light for the job.
• In summer Crowthorne gets around 16h 37m of daylight, but early deliveries still beat the traffic and give the longest working day.
• For a phased build we can split the order so materials arrive as each stage starts, which keeps the site clear.

Damp Proofing & Membranes questions

Is there a minimum order for delivery to Crowthorne?

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 you supply cavity trays?

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

Can I add other materials to my Crowthorne 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.
