PROVEN SOLUTIONS: Specially Engineered Vent Barriers Solve Flooding Issues In Subways And Other Underground Urban Infrastructure
Ventilation openings that provide airflow to underground infrastructure also create a major vulnerability during severe weather. Flash flooding, storm surge and rapidly rising surface water can quickly overwhelm traditional vent openings, allowing water to enter underground systems within minutes. Once floodwater penetrates these spaces, the result can be catastrophic, leading to equipment damage, electrical failures, service interruptions, costly repairs and dangerous conditions for both workers and the public. As climate patterns continue to produce more intense rainfall events, cities are increasingly challenged to protect vulnerable underground infrastructure without compromising the ventilation systems required for normal operation.
