Sizing your order

An extension in Bonnyrigg with 24 m of cavity wall needs DPC in both leaves: about 2 rolls in 30 m lengths once laps are allowed for. A 50 m² floor slab needs about 57.5 m² of DPM including laps, which is 1 roll of 4 × 25 m sheeting.

Picking the right product

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; the council's building standards service will tell you what applies.

In Scotland most building work needs a building warrant from the local authority, assessed against the Building Standards Technical Handbooks.

Before your Bonnyrigg delivery arrives

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

• On busy streets in Bonnyrigg, a parking suspension or a quiet time slot can make offloading safer, so tell us about local restrictions you know of.
• If the drop point is block paving or soft ground, say so; heavy pallets and bulk bags can mark or sink.
• Pallets left on a pavement can block the footway, so plan a drop point inside your boundary where you can.
