Picking the right product

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.

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.

Delivery to Ossett: what helps

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

• If the drop point is block paving or soft ground, say so; heavy pallets and bulk bags can mark or sink.
• On busy streets in Ossett, a parking suspension or a quiet time slot can make offloading safer, so tell us about local restrictions you know of.
• Tell us the best drop point, such as a driveway, front garden or the kerb, and whether a lorry can park close to it.

Estimating your damp proofing

An extension in Ossett with 24 m of cavity wall needs DPC in both leaves: about 2 rolls in 30 m lengths once laps are allowed for. A 40 m² floor slab needs about 46 m² of DPM including laps, which is 1 roll of 4 × 25 m sheeting.

Damp Proofing & Membranes in Ossett: questions

Is there a minimum order for delivery to Ossett?

There is no fixed minimum. For very small orders we will tell you honestly if the delivery cost outweighs the materials, so you can decide.

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 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.

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

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