An extension in Llandrindod Wells with 24 m of cavity wall needs DPC in both leaves: about 2 rolls in 30 m lengths once laps are allowed for. A 50 m² floor slab needs about 57.5 m² of DPM including laps, which is 1 roll of 4 × 25 m sheeting.

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.
