Before your Greenock delivery arrives

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

• If neighbours share the access, it helps to let them know a lorry is coming.
• In summer Greenock gets around 17h 36m of daylight, but early deliveries still beat the traffic and give the longest working day.
• For a phased build we can split the order so materials arrive as each stage starts, which keeps the site clear.

Estimating your damp proofing

An extension in Greenock with 20 m of cavity wall needs DPC in both leaves: about 2 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.

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 questions

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

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.

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.

Where does the DPC go?

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

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

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