Picking the right product

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.

Planning the drop in Darlington

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

• Give us the full postcode for the drop point; deliveries around DL3 are priced to the exact address.
• Tell us the best drop point, such as a driveway, front garden or the kerb, and whether a lorry can park close to it.
• Pallets left on a pavement can block the footway, so plan a drop point inside your boundary where you can.

A quick quantity check

An extension in Darlington with 28 m of cavity wall needs DPC in both leaves: about 3 rolls in 30 m lengths once laps are allowed for. A 15 m² floor slab needs about 17.2 m² of DPM including laps, which is 1 roll of 4 × 25 m sheeting.

Damp Proofing & Membranes questions

How soon can damp proofing be delivered in Darlington?

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.

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.

Where does the DPC go?

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

Is there a minimum order for delivery to Darlington?

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.
