How much will you need?

An extension in County Armagh with 12 m of cavity wall needs DPC in both leaves: about 1 roll 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.

Planning the drop in County Armagh

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 site is up a shared drive or behind other houses, tell us the distance from the road.
• If neighbours share the access, it helps to let them know a lorry is coming.
• For a phased build we can split the order so materials arrive as each stage starts, which keeps the site clear.

Damp Proofing & Membranes: choosing well

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.

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 County Armagh

Can you deliver damp proofing to a site with restricted access in County Armagh?

Where does the DPC go?

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

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.
