A quick quantity check

An extension in Derbyshire with 36 m of cavity wall needs DPC in both leaves: about 3 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.

Delivery to Derbyshire: what helps

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

• If the drop point is block paving or soft ground, say so; heavy pallets and bulk bags can mark or sink.
• If the site is up a shared drive or behind other houses, tell us the distance from the road.
• Mention any overhead cables, low branches or narrow gateways, because they decide whether a crane offload is possible.

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.

Ordering damp proofing for Derbyshire: FAQs

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

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

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.

Can I add other materials to my Derbyshire 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.

Where does the DPC go?

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