A quick quantity check

An extension in Sheffield with 16 m of cavity wall needs DPC in both leaves: about 2 rolls in 30 m lengths once laps are allowed for. A 40 m² floor slab needs about 46 m² of DPM including laps, which is 1 roll of 4 × 25 m sheeting.

Getting the right damp proofing

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.

Delivery to Sheffield: what helps

Rolls are light enough to travel with a mixed load and are handed off at the kerb. Sheffield 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 S1 are priced to the exact address.
• Keep cement, plaster and boards dry: have a tarpaulin or a garage space ready before they arrive.

Your questions answered

Can you deliver damp proofing to a site with restricted access in Sheffield?

Usually, yes. Tell us about the access when you ask for a price and we will plan the vehicle and offload, or say if a smaller vehicle is needed.

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.

Can I add other materials to my Sheffield 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.
