Quantities: a worked example

An extension in Cumbria 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.

Delivering damp proofing in Cumbria

Rolls are light enough to travel with a mixed load and are handed off at the kerb. Our standard mainland delivery area covers Cumbria.

• If the drop point is block paving or soft ground, say so; heavy pallets and bulk bags can mark or sink.
• Keep cement, plaster and boards dry: have a tarpaulin or a garage space ready before they arrive.
• Clear a level area for pallets, ideally on boards, so materials stay out of standing water.

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.

Common questions from Cumbria

Where does the DPC go?

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

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.

Do you deliver damp proofing to trades and homeowners in Cumbria?

Both. Trades can apply for a trade account; homeowners and self-builders can order on a delivered quote.

How soon can damp proofing be delivered in Cumbria?

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.
