Rainscreen and wall drainage plane
Use cladding as the first line of defence while preserving a continuous path behind it to manage, drain and dry water that gets through.
VERT / GREEN
Identify cladding, membrane, cavity, flashings and drainage exits before retrofit.
JAUNE / YELLOW
A cavity bridged by mortar/debris, blocked weeps or discontinuous flashing turns a drained system into a water trap.
ROUGE / RED
Active leakage, discontinuous membrane/flashing or decay behind cladding: open enough to repair the water path, not just recaulk the face.
Useful tools and data
- Wall section
- Weep/flashing photos
- Leakage map
What the professional checks
