Estimating your damp proofing

An extension in Maidstone with 20 m of cavity wall needs DPC in both leaves: about 2 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.

Picking the right product

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 Maidstone

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

• Clear a level area for pallets, ideally on boards, so materials stay out of standing water.
• Keep cement, plaster and boards dry: have a tarpaulin or a garage space ready before they arrive.
• If the site is up a shared drive or behind other houses, tell us the distance from the road.

Your questions answered

Where does the DPC go?

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

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

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

Can I add other materials to my Maidstone 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.

Do I need a radon barrier?

It depends on where you are. In radon-affected areas building control requires radon protection in new buildings and extensions.
