Our damp proofing range for Flint jobs

• Radon barriersGas-resistant membranes for areas that need radon protection.
• DPM sheetingHeavy-gauge polythene membrane under concrete floors.
• DPC rollsPolymer and bitumen damp-proof course in standard wall widths.
• Weep ventsFor drainage and ventilation at the base of cavities and over trays.

Quantities: a worked example

An extension in Flint with 28 m of cavity wall needs DPC in both leaves: about 3 rolls in 30 m lengths once laps are allowed for. A 15 m² floor slab needs about 17.2 m² of DPM including laps, which is 1 roll of 4 × 25 m sheeting.

Delivery to Flint: what helps

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

• Keep cement, plaster and boards dry: have a tarpaulin or a garage space ready before they arrive.
• Pallets left on a pavement can block the footway, so plan a drop point inside your boundary where you can.
• In summer Flint gets around 16h 59m of daylight, but early deliveries still beat the traffic and give the longest working day.

Before you order damp proofing

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.

Wales has its own Approved Documents, including its own Part L for energy efficiency, and building control is handled by the local authority or a registered approver.

Your questions answered

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

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

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.

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.
