Smart Vent Products is the leading manufacturer of foundation flood venting systems and has an ICC-ES Certified product line with dual-function and insulated engineered models for residential and commercial applications.

ILC Dover and Smart Vent have partnered and developed technology that makes Dry Floodproofing non-residential buildings a safer option. The line of Dry Floodproofing Products is called the Flex-Wall®.

The Flex-Wall® is a high strength flexible wall that can be deployed rapidly for flood protection of buildings or equipment. It is constructed from textile-based materials and metal posts that reside in a small container and are manually deployed. The Flex-Wall can be long, to surround buildings, or short, to close off doorways. All parts and equipment are stored at the point-of-use for maximum efficiency in an emergency.

Flex-Wall® provides a second-to-none dry floodproofing option:

  • Point-of-use storage: eliminating the need for off-site storage and fees
  • Rapid deployment: deploy in minutes with minimal manpower and no heavy equipment
  • Scalable designs: can be sized to fit any opening or threat
  • Robust construction & advanced materials: constructed with layered Kevlar® structural webbing with a coated fabric water retention layer
