Getting the right damp proofing

Laps and joints

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

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.

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.

Sizing your order

An extension in Ipswich 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.

Getting damp proofing onto your Ipswich site

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

• Weight limits on bridges or private roads near the site matter for larger lorries, so mention any you know of.
• If the site is up a shared drive or behind other houses, tell us the distance from the road.
• Pallets left on a pavement can block the footway, so plan a drop point inside your boundary where you can.

Common questions from Ipswich

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

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

Where does the DPC go?

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

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.

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

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.
