Quantities: a worked example

An extension in Sandown with 20 m of cavity wall needs DPC in both leaves: about 2 rolls in 30 m lengths once laps are allowed for. A 25 m² floor slab needs about 28.7 m² of DPM including laps, which is 1 roll of 4 × 25 m sheeting.

Getting damp proofing onto your Sandown site

Rolls are light enough to travel with a mixed load and are handed off at the kerb. Sandown needs a ferry crossing, so deliveries are quoted individually with the crossing included.

• Keep cement, plaster and boards dry: have a tarpaulin or a garage space ready before they arrive.
• If the drop point is block paving or soft ground, say so; heavy pallets and bulk bags can mark or sink.
• If neighbours share the access, it helps to let them know a lorry is coming.

Damp Proofing & Membranes: choosing well

DPC width

Match the DPC width to the wall leaf so it runs the full width of the masonry.

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.

Damp Proofing & Membranes in Sandown: questions

What is the difference between DPC and DPM?

DPC is a strip built into walls to stop damp rising through the masonry. DPM is a sheet laid under a concrete floor slab. They are lapped together so there is no gap.

Is there a minimum order for delivery to Sandown?

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.

How soon can damp proofing be delivered in Sandown?

We confirm the delivery date when we price your order, before you commit. It depends on the product, the quantity and whether it is a stock line or made to order.
