GARAGE OPENINGS
Below-grade garages can funnel surface water toward the building.
Garage flood protection can involve a flood-resistant door, engineered barrier, drainage improvements or a combination of measures. The right design depends on opening width, approach slope, drain capacity, structure and expected water conditions.
Review the driveway slope and low point
Measure the full garage opening
Assess trench drains and surface-water routing
Plan normal garage operation and emergency access
