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 England, building work is checked against the Approved Documents, for example Part A for structure and Part L for energy efficiency, through your council's building control team or a registered building control approver.
