Delivery to Banbridge: what helps

Rolls are light enough to travel with a mixed load and are handed off at the kerb. Deliveries to Northern Ireland include a sea crossing, so we quote each order individually.

• If the drop point is block paving or soft ground, say so; heavy pallets and bulk bags can mark or sink.
• For a phased build we can split the order so materials arrive as each stage starts, which keeps the site clear.
• Deliveries are to the kerb, drive or within crane reach; ask if materials need to go further.

Damp Proofing & Membranes: choosing well

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.

In Northern Ireland building work follows the Building Regulations (Northern Ireland), with guidance in the Technical Booklets, and applications go to the council's building control team.

Questions about damp proofing delivery in Banbridge

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.

Can I add other materials to my Banbridge 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.

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

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