Picking the right product

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.

How delivery works in Bexley

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

• Clear a level area for pallets, ideally on boards, so materials stay out of standing water.
• In summer Bexley gets around 16h 38m of daylight, but early deliveries still beat the traffic and give the longest working day.
• Weight limits on bridges or private roads near the site matter for larger lorries, so mention any you know of.

Working out quantities for your Bexley job

An extension in Bexley with 28 m of cavity wall needs DPC in both leaves: about 3 rolls in 30 m lengths once laps are allowed for. A 15 m² floor slab needs about 17.2 m² of DPM including laps, which is 1 roll of 4 × 25 m sheeting.

Damp Proofing & Membranes questions

How thick should a DPM be?

1200-gauge polythene, around 300 microns, is a common specification for floor slabs. Your design may call for something different.

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.
