Getting the right 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 Wallington with 28 m of cavity wall needs DPC in both leaves: about 3 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.

Delivery to Wallington: what helps

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

• Deliveries are to the kerb, drive or within crane reach; ask if materials need to go further.
• In summer Wallington gets around 16h 37m of daylight, but early deliveries still beat the traffic and give the longest working day.
• Weight limits on bridges or private roads near the site matter for larger lorries, so mention any you know of.

Damp Proofing & Membranes questions

Where does the DPC go?

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

How thick should a DPM be?

1200-gauge polythene, around 300 microns, is a common specification for floor slabs. Your design may call for something different.

Can I add other materials to my Wallington 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.

Is there a minimum order for delivery to Wallington?

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.
