Choosing from our damp proofing range

• Radon barriersGas-resistant membranes for areas that need radon protection.

• DPC rollsPolymer and bitumen damp-proof course in standard wall widths.

Estimating your damp proofing

An extension in Kidderminster with 32 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.

Getting damp proofing onto your Kidderminster site

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

• With roughly 7h 40m of daylight in Kidderminster 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.
• If the drop point is block paving or soft ground, say so; heavy pallets and bulk bags can mark or sink.

Getting the right damp proofing

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.

Damp Proofing & Membranes in Kidderminster: questions

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.

Can I add other materials to my Kidderminster 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.

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

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