Getting damp proofing onto your Failsworth site

Rolls are light enough to travel with a mixed load and are handed off at the kerb. Failsworth 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.
• On busy streets in Failsworth, a parking suspension or a quiet time slot can make offloading safer, so tell us about local restrictions you know of.
• In summer Failsworth gets around 17h 02m of daylight, but early deliveries still beat the traffic and give the longest working day.

Damp Proofing & Membranes: choosing well

DPC width

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

Laps and joints

DPM and DPC need generous laps and sealed joints; follow the manufacturer's guidance.

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.

Estimating your damp proofing

An extension in Failsworth with 20 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.

Damp Proofing & Membranes questions

Do I need a radon barrier?

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

Where does the DPC go?

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

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

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 Failsworth?

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