Before your Penicuik delivery arrives

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

• For a phased build we can split the order so materials arrive as each stage starts, which keeps the site clear.
• If the drop point is block paving or soft ground, say so; heavy pallets and bulk bags can mark or sink.
• Tell us the best drop point, such as a driveway, front garden or the kerb, and whether a lorry can park close to it.

Working out quantities for your Penicuik job

An extension in Penicuik with 12 m of cavity wall needs DPC in both leaves: about 1 roll 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.

Choosing damp proofing

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.

Damp Proofing & Membranes in Penicuik: questions

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

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 Penicuik?

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

What is the difference between DPC and DPM?

DPC is a strip built into walls to stop damp rising through the masonry. DPM is a sheet laid under a concrete floor slab. They are lapped together so there is no gap.

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.
