Aquafragma self-operated flood barrier™

aquafragma - self-operated flood barrier™

hidden inside pavement for zero visual disruption

automatic operation

full protection achieved before flood reaches pavement level

no power required operates by buoyancy action only

The gate is normally securely locked flush with floor

Buoyancy action makes the buoyant body to rotate and lift the gate upwards

The gate turns to upright position before flood level reaches pavement level

The upright gate prevents the entry of flood water into the protected area

innovation and advantages

The barrier is self-operated, requiring no power and no human intervention
The gate turns to upright position just before flood water reaches the protected area thereby:

It requires no side walls
It requires no threshold/ step
It is trafficable up to the ultimate instant

It requires little if any excavation
