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.

Sizing your order

An extension in Pimlico with 12 m of cavity wall needs DPC in both leaves: about 1 roll 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.

Delivering damp proofing in Pimlico

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

• Pallets left on a pavement can block the footway, so plan a drop point inside your boundary where you can.
• Keep cement, plaster and boards dry: have a tarpaulin or a garage space ready before they arrive.
• On busy streets in Pimlico, a parking suspension or a quiet time slot can make offloading safer, so tell us about local restrictions you know of.

Damp Proofing & Membranes questions

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.

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.

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

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

How soon can damp proofing be delivered in Pimlico?

We confirm the delivery date when we price your order, before you commit. It depends on the product, the quantity and whether it is a stock line or made to order.
