Picking the right product

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.

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.

Before your Selby delivery arrives

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

• Pallets left on a pavement can block the footway, so plan a drop point inside your boundary where you can.
• Deliveries are to the kerb, drive or within crane reach; ask if materials need to go further.
• Have someone on site for the delivery if you can, or agree a safe drop point with us in advance.

Working out quantities for your Selby job

An extension in Selby with 24 m of cavity wall needs DPC in both leaves: about 2 rolls in 30 m lengths once laps are allowed for. A 15 m² floor slab needs about 17.2 m² of DPM including laps, which is 1 roll of 4 × 25 m sheeting.

Damp Proofing & Membranes questions

Where does the DPC go?

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

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.

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.
