Before you order damp proofing

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.

DPC width

Match the DPC width to the wall leaf so it runs the full width of the masonry.

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.

Getting damp proofing onto your Falmouth site

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

• In summer Falmouth gets around 16h 24m of daylight, but early deliveries still beat the traffic and give the longest working day.
• Give us the full postcode for the drop point; deliveries around TR11 are priced to the exact address.
• 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 Falmouth job

An extension in Falmouth with 24 m of cavity wall needs DPC in both leaves: about 2 rolls in 30 m lengths once laps are allowed for. A 25 m² floor slab needs about 28.7 m² of DPM including laps, which is 1 roll of 4 × 25 m sheeting.

Damp Proofing & Membranes questions

Where does the DPC go?

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

Can I add other materials to my Falmouth delivery?

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.

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.

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

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