Delivery to Hawarden: what helps

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

• On busy streets in Hawarden, a parking suspension or a quiet time slot can make offloading safer, so tell us about local restrictions you know of.
• In summer Hawarden gets around 16h 58m of daylight, but early deliveries still beat the traffic and give the longest working day.
• Weight limits on bridges or private roads near the site matter for larger lorries, so mention any you know of.

Quantities: a worked example

An extension in Hawarden with 16 m of cavity wall needs DPC in both leaves: about 2 rolls in 30 m lengths once laps are allowed for. A 30 m² floor slab needs about 34.5 m² of DPM including laps, which is 1 roll of 4 × 25 m sheeting.

Picking the right product

Laps and joints

DPM and DPC need generous laps and sealed joints; follow the manufacturer's guidance.

DPC width

Match the DPC width to the wall leaf so it runs the full width of the masonry.

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

Is there a minimum order for delivery to Hawarden?

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.

Can I add other materials to my Hawarden 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.

What is the difference between DPC and DPM?

DPC is a strip built into walls to stop damp rising through the masonry. DPM is a sheet laid under a concrete floor slab. They are lapped together so there is no gap.
