Things to check before you order

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.

How much will you need?

An extension in Tewkesbury 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.

Delivery to Tewkesbury: what helps

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

• Weight limits on bridges or private roads near the site matter for larger lorries, so mention any you know of.
• Pallets left on a pavement can block the footway, so plan a drop point inside your boundary where you can.
• In summer Tewkesbury gets around 16h 44m of daylight, but early deliveries still beat the traffic and give the longest working day.

Common questions from Tewkesbury

Is there a minimum order for delivery to Tewkesbury?

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 you deliver damp proofing to trades and homeowners in Tewkesbury?

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

Where does the DPC go?

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