The largest and most stable freely scalable rainwater retention system in the world.
Simply BIG reflects the true scale – 2.5 m × 2.5 m × 2.5 m.
Simply STRONG defines the strength – Load Capacity Class F 900 and beyond.
Preventive infrastructure measures are not only more effective, but also far more cost-efficient than dealing with the destruction caused by floods and inundations after the fact.

The JUMBO BLOCK® Dashboard gives municipalities real-time insight into water levels, system performance, and on-site conditions.
Connected via IoT and secured through IOTA technology, it enables precise monitoring, automated alerts, and reliable decision-making — directly from installed JUMBO BLOCK® modules.
This combination of physical resilience and digital transparency helps cities manage heavy rainfall, optimize operations, and strengthen local water infrastructure.
A live dashboard is available for demonstration purposes.
It provides transparent insight into real-time sensor data, system status, and monitoring functions — allowing municipalities to experience digital preparedness in practice:
