Damp Proofing & Membranes: choosing well

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.

Before your Wednesbury delivery arrives

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

• Mention any overhead cables, low branches or narrow gateways, because they decide whether a crane offload is possible.
• Tell us the best drop point, such as a driveway, front garden or the kerb, and whether a lorry can park close to it.
• If the site is up a shared drive or behind other houses, tell us the distance from the road.

A quick quantity check

An extension in Wednesbury with 20 m of cavity wall needs DPC in both leaves: about 2 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.

Your questions answered

Can I add other materials to my Wednesbury 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.

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.

Do you supply cavity trays?

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

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

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.
