Picking the right product

Laps and joints

DPM and DPC need generous laps and sealed joints; follow the manufacturer's guidance.

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.

Before your Eltham delivery arrives

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

• If the site is up a shared drive or behind other houses, tell us the distance from the road.
• Pallets left on a pavement can block the footway, so plan a drop point inside your boundary where you can.
• In summer Eltham gets around 16h 38m of daylight, but early deliveries still beat the traffic and give the longest working day.

A quick quantity check

An extension in Eltham with 16 m of cavity wall needs DPC in both leaves: about 2 rolls in 30 m lengths once laps are allowed for. A 50 m² floor slab needs about 57.5 m² of DPM including laps, which is 1 roll of 4 × 25 m sheeting.

Questions about damp proofing delivery in Eltham

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

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

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.

How soon can damp proofing be delivered in Eltham?

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.
