Things to check before you order

DPC width

Match the DPC width to the wall leaf so it runs the full width of the masonry.

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.

How delivery works in Croydon

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

• Mention any overhead cables, low branches or narrow gateways, because they decide whether a crane offload is possible.
• Tell us the best drop point, such as a driveway, front garden or the kerb, and whether a lorry can park close to it.
• Deliveries are to the kerb, drive or within crane reach; ask if materials need to go further.

Sizing your order

An extension in Croydon with 28 m of cavity wall needs DPC in both leaves: about 3 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.

Damp Proofing & Membranes in Croydon: 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.

Do you supply cavity trays?

Yes, with stop ends and weep vents for openings and abutments.

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

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.

How soon can damp proofing be delivered in Croydon?

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.
