Automatic Hydrodynamic Flood Gate
DamGuard’s Automatic Hydrodynamic Flood Gate is engineered to defend underground garages, tunnels, and critical access points without human intervention or power supply. Using the force of rising water itself, the gate automatically lifts into position—creating a watertight retaining wall that protects vehicles, infrastructure, and property.
DamGuard-inc’s Automatic Hydrodynamic Flood Gate
DamGuard-inc’s Automatic Hydrodynamic Flood Gate is engineered to defend underground garages, tunnels, and critical access points without human intervention or power supply. Using the force of rising water itself, the gate automatically lifts into position—creating a watertight retaining wall that protects vehicles, infrastructure, and property.
Passive Deployment: No electricity, motors, or human action required—water pressure activates the barrier automatically.
Seamless Design: Hidden below ground when not in use, allowing full access for vehicles and pedestrians.
Strong & Secure: Heavy-duty construction and self-sealing gaskets form a tight water-retaining wall that withstands extreme flood pressure.
Trusted by Experts: Preferred by FEMA for its reliability and resilience, with minimal maintenance required.
Peace of Mind: Always on standby, protecting the spaces you can’t afford to lose.
The Hydrodynamic Flood Gate turns rising water into its own defense—ensuring underground garages and critical facilities stay dry, safe, and operational.
Specifications.
DamGuard’s Inground Hydrodynamic Passive Flood Barriers provide automatic, invisible, and maintenance-light protection against flooding. Aligned with FEMA’s guidance on passive flood mitigation measures, these systems function day or night, without power or human intervention, ensuring reliable protection for homes, businesses, and critical infrastructure.
FEMA-Aligned Design Advantages
Passive Mitigation (FEMA Preferred):
Operates automatically using hydrostatic pressure, no manual or powered activation.Invisible & Architecturally Neutral:
Fully recessed into the ground when not in use, blending seamlessly into entryways, roads, and walkways.Durable & Long Service Life:
Constructed from marine-grade aluminum and stainless steel with EPDM/neoprene seals; resistant to rust, corrosion, and saltwater exposure.Minimal Maintenance:
Requires only a simple annual inspection by a small crew; no heavy servicing.Shallow Installation:
Horizontal trench design allows for shallow set-down foundations, minimizing excavation costs.
Operating Concept
Normal Condition: Barrier beam lies flush with ground; pedestrians and vehicles pass freely.
Flood Condition: Rising water fills buoyancy chamber; the beam floats upward.
Full Deployment: Beam seals against sidewalls at 90° vertical, locked by hydrostatic pressure.
Recession: As waters subside, the barrier automatically lowers back into its recessed housing.
Integration with DamGuard Aegis™
Realtime Monitoring: Centralized dashboards for municipal clients.
Home & Mobile Panels: Status alerts for homeowners and businesses.
Forecasting: AI + NOAA flood data integration.
Diagnostics: Remote monitoring of barrier activation and seal integrity
Applications
Residential: driveways, garages, basements.
Commercial: warehouses, retail, logistics hubs.
Critical Infrastructure: ports, data centers, hospitals.
Municipal: underpasses, transit stations, road tunnels.
Compliance Note
DamGuard barriers align with FEMA’s preference for passive mitigation as outlined in hazard mitigation planning guidance. Passive systems are recognized as more reliable than active systems due to their automatic function, minimal maintenance, and long service life.
