Things to check before you order

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.

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.

Working out quantities for your Holyhead job

An extension in Holyhead with 32 m of cavity wall needs DPC in both leaves: about 3 rolls in 30 m lengths once laps are allowed for. A 25 m² floor slab needs about 28.7 m² of DPM including laps, which is 1 roll of 4 × 25 m sheeting.

Getting damp proofing onto your Holyhead site

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

• On busy streets in Holyhead, a parking suspension or a quiet time slot can make offloading safer, so tell us about local restrictions you know of.
• In summer Holyhead gets around 17h 00m of daylight, but early deliveries still beat the traffic and give the longest working day.
• Deliveries are to the kerb, drive or within crane reach; ask if materials need to go further.

Common questions from Holyhead

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.

Where does the DPC go?

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

Is there a minimum order for delivery to Holyhead?

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 soon can damp proofing be delivered in Holyhead?

We confirm the delivery date when we price your order, before you commit. It depends on the product, the quantity and whether it is a stock line or made to order.
