Quantities: a worked example

An extension in Deal with 32 m of cavity wall needs DPC in both leaves: about 3 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.

Before you order 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.

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.

Delivering damp proofing in Deal

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

• In summer Deal gets around 16h 35m 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.
• If neighbours share the access, it helps to let them know a lorry is coming.

Damp Proofing & Membranes questions

Can I add other materials to my Deal 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.

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.

How soon can damp proofing be delivered in Deal?

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.

Where does the DPC go?

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