Sizing your order

An extension in Perth and Kinross with 24 m of cavity wall needs DPC in both leaves: about 2 rolls in 30 m lengths once laps are allowed for. A 20 m² floor slab needs about 23 m² of DPM including laps, which is 1 roll of 4 × 25 m sheeting.

Getting damp proofing onto your Perth and Kinross site

Rolls are light enough to travel with a mixed load and are handed off at the kerb. Our standard mainland delivery area covers Perth and Kinross.

• Keep cement, plaster and boards dry: have a tarpaulin or a garage space ready before they arrive.
• If neighbours share the access, it helps to let them know a lorry is coming.
• Mention any overhead cables, low branches or narrow gateways, because they decide whether a crane offload is possible.

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.

Your questions answered

Can you deliver damp proofing to a site with restricted access in Perth and Kinross?

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.

Do you deliver damp proofing to trades and homeowners in Perth and Kinross?

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

Do you supply cavity trays?

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

Do I need a radon barrier?

It depends on where you are. In radon-affected areas building standards require radon protection in new buildings and extensions.
