Damp Proofing & Membranes: choosing well

DPC width

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

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.

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.

Working out quantities for your York job

An extension in York 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.

Planning the drop in York

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

• If neighbours share the access, it helps to let them know a lorry is coming.
• Give us the full postcode for the drop point; deliveries around YO1 are priced to the exact address.
• If the drop point is block paving or soft ground, say so; heavy pallets and bulk bags can mark or sink.

Common questions from York

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.

Can I add other materials to my York 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.

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

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