DPC width

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.

How delivery works in Derby

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

• Give us the full postcode for the drop point; deliveries around DE1 are priced to the exact address.
• For a phased build we can split the order so materials arrive as each stage starts, which keeps the site clear.
• Weight limits on bridges or private roads near the site matter for larger lorries, so mention any you know of.

Working out quantities for your Derby job

An extension in Derby with 24 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.

Questions about damp proofing delivery in Derby

Where does the DPC go?

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

How thick should a DPM be?

1200-gauge polythene, around 300 microns, is a common specification for floor slabs. Your design may call for something different.

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

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.

Can I add other materials to my Derby 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.
