Quantities: a worked example

An extension in Holywood 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.

How delivery works in Holywood

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.

• Keep cement, plaster and boards dry: have a tarpaulin or a garage space ready before they arrive.
• Pallets left on a pavement can block the footway, so plan a drop point inside your boundary where you can.
• In summer Holywood gets around 17h 17m of daylight, but early deliveries still beat the traffic and give the longest working day.

Picking the right product

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.
