Sizing your order

An extension in Nelson with 32 m of cavity wall needs DPC in both leaves: about 3 rolls in 30 m lengths once laps are allowed for. A 30 m² floor slab needs about 34.5 m² of DPM including laps, which is 1 roll of 4 × 25 m sheeting.

Picking the right product

Laps and joints

DPM and DPC need generous laps and sealed joints; follow the manufacturer's guidance.

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.

How delivery works in Nelson

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

• Deliveries are to the kerb, drive or within crane reach; ask if materials need to go further.
• Clear a level area for pallets, ideally on boards, so materials stay out of standing water.
• Tell us the best drop point, such as a driveway, front garden or the kerb, and whether a lorry can park close to it.

Your questions answered

Where does the DPC go?

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

Do you supply cavity trays?

Yes, with stop ends and weep vents for openings and abutments.

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

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

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.
