Designed to provide totally unrestricted access to pedestrian and vehicle entrances, this self-raising flood barrier is fully recessed in to the ground when not in use. A range of surface finishes is available; from skid resistant epoxy coatings to timber cladding or paving to fit in with the external hard landscaping. These flood barriers can rise automatically with the rising flood waters or by push button in advance keeping you in control for complete peace of mind. Uninterruptible Power Supply (UPS) and manual backups mean these barriers will not let you down. Installation width can be up to 20 m, effective barrier height can be up to 1,5 m. Movement and safety sensors prevent the barriers opening if the entrance is obstructed whilst optional audio/visual alarms sound prior to and during operation. Optional 24 volt back-up systems are available for use in the event of mains failure and permanently installed security grates cover the housing pit – serving as both a safety platform for traffic and pedestrians and as protection for the hydraulic system while the barrier remains raised. These barriers are designed for pedestrian and vehicle entrances, or anywhere where unrestricted level access is required.
