Damp Proofing & Membranes: choosing well

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.

• With roughly 7h 21m of daylight in Barrow-in-Furness around the shortest day, morning deliveries leave more working light for the job.

Your questions answered

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 I add other materials to my Barrow-in-Furness 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.
