Floodproofing Vent Systems

Floodproofing vent systems provide passive wet floodproofing by allowing controlled water entry to equalize hydrostatic pressure and reduce structural damage.

Engineered, Permitted, Installed, and Supported by FloodReady

FloodReady delivers code-compliant flood vent systems for commercial and critical facilities across Southwest Florida, engineered and coordinated with building conditions, floodplain requirements, and regulatory approvals, then professionally installed and supported long term.

System Applications

Floodproofing vent systems are required or recommended for enclosed areas subject to flood exposure where wet-floodproofing is an appropriate mitigation strategy.

Common applications include:

  • Existing buildings requiring floodplain compliance

  • Ground-level enclosures below flood elevation

  • Attached and detached garages

  • Utility and storage enclosures

Flood vents installed in enclosed parking structure to equalize hydrostatic pressure during flood events

System Considerations

System selection depends on site conditions, operational needs, and long-term ownership considerations.

    • Designed to equalize hydrostatic pressure

    • Certified to ICC-ES and FEMA requirements

    • Engineered for debris passage and flow

    • Passive, automatically activated operation

    • No manual deployment or power required

    • Bi-directional opening for pressure equalization

    • Minimal maintenance requirements

    • Integrated into wall assemblies

    • Inspection and long-term support provided

System Configurations

Floodproofing vent systems are selected and configured based on enclosure size, flood zone classification, ventilation needs, and thermal performance requirements.


Floodproofing Vent Systems

Manufacturer:
Smart Vent of Floodproofing.com

ICC-ES certified wet-floodproofing vents protect buildings by self-equalizing hydrostatic pressure to prevent damage to walls and foundations causing structural failure. During flood events, vents open automatically to allow water flow and relieve pressure, then close once water recedes.

  • Passive, automatic flood activation

  • Bi-directional swing for pressure relief

  • Designed for debris clearance

  • No deployment or power required

  • Dual-Function Flood Vents

Dual-function flood vent unit designed for automatic floodwater equalization and non-flood ventilation

Dual-function flood vents provide both everyday ventilation and automatic flood protection through temperature-responsive or gravity-operated louvers. These systems are well suited for non-conditioned spaces requiring continuous airflow.

  • Insulated Flood Vents

Insulated flood vent assembly designed for conditioned spaces requiring thermal performance and flood compliance

Insulated flood vents are designed for conditioned or semi-conditioned spaces where thermal performance is required in addition to flood compliance. These systems incorporate sealed, insulated panels that remain closed under normal conditions and automatically open during flood events to equalize pressure while maintaining energy efficiency when not flooding.

The FloodReady Difference

FloodReady delivers engineered flood protection systems through professional design, permitting, installation, and long-term support, ensuring systems perform as intended when flood conditions occur.

Engineering-Led

Flood protection systems are engineered for site-specific flood conditions, loading assumptions, and operational constraints, not selected from standard product catalogs.

Permitting Expertise

FloodReady coordinates building and floodplain permitting to ensure systems meet regulatory requirements and are accepted by local authorities having jurisdiction.

Integrated Retrofit

FloodReady integrates flood vents into existing wall assemblies with precise detailing while preserving structural integrity, finishes, and long-term performance.



Lifecycle Support

FloodReady provides training, inspections, and ongoing service to maintain system readiness throughout ownership, beyond initial installations.
