Flashing Is Not a Detail. It’s a Pressure Valve.
Inside every masonry wall is a hidden weather system.
Moisture enters through hairline cracks, vapor pressure rises, and without a release route, damage blooms from the inside out.
That’s where thru-wall flashing operates:
1. Capillarity Control
Flashing is a hydrophobic break that redirects water downward. But the slope, overlap, and continuity must follow fluid dynamics, not guesswork.
2. Drainage Orchestration
Weep holes are the exit valves. But if spacing is too wide, or backfill is clogged, hydrostatic pressure builds. We verify drainage plane functionality using tracer dyes and infrared.
3. Material Chemistry
Copper, stainless steel, and EPDM each behave differently over time. Flashings must be galvanically compatible with anchors, breathable when needed, and UV-stable across decades.
Flashing is not optional. It’s the engineered pause button that protects the entire facade from collapse by allowing walls to exhale.
