Choosing 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.

Delivery to Newcastle upon Tyne: what helps

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

• Keep cement, plaster and boards dry: have a tarpaulin or a garage space ready before they arrive.
• In summer Newcastle upon Tyne gets around 17h 22m of daylight, but early deliveries still beat the traffic and give the longest working day.
• Pallets left on a pavement can block the footway, so plan a drop point inside your boundary where you can.

How much will you need?

An extension in Newcastle upon Tyne with 16 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.
