Damp Proofing & Membranes for Epsom, delivered to site

Choosing from our damp proofing range

• DPM sheetingHeavy-gauge polythene membrane under concrete floors.
• Cavity trays and stop endsTo direct water out of the cavity over openings.
• DPC rollsPolymer and bitumen damp-proof course in standard wall widths.
• Radon barriersGas-resistant membranes for areas that need radon protection.

How much will you need?

An extension in Epsom with 36 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.

How delivery works in Epsom

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

• Tell us the best drop point, such as a driveway, front garden or the kerb, and whether a lorry can park close to it.
• With roughly 7h 51m of daylight in Epsom around the shortest day, morning deliveries leave more working light for the job.
• Weight limits on bridges or private roads near the site matter for larger lorries, so mention any you know of.

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.

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.

Your questions answered

How soon can damp proofing be delivered in Epsom?

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.

Can I add other materials to my Epsom 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.

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.

Where does the DPC go?

Usually at least 150 mm above outside ground level, linked to the floor DPM.
