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.

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 Haverhill with 24 m of cavity wall needs DPC in both leaves: about 2 rolls in 30 m lengths once laps are allowed for. A 20 m² floor slab needs about 23 m² of DPM including laps, which is 1 roll of 4 × 25 m sheeting.

Delivery to Haverhill: what helps

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

• With roughly 7h 44m of daylight in Haverhill around the shortest day, morning deliveries leave more working light for the job.
• In summer Haverhill gets around 16h 45m of daylight, but early deliveries still beat the traffic and give the longest working day.
• Keep cement, plaster and boards dry: have a tarpaulin or a garage space ready before they arrive.

Damp Proofing & Membranes in Haverhill: questions

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

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

Can I add other materials to my Haverhill 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.

What is the difference between DPC and DPM?

DPC is a strip built into walls to stop damp rising through the masonry. DPM is a sheet laid under a concrete floor slab. They are lapped together so there is no gap.

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.
