Large-Scale Rainwater Retention and Storage

Resilient Adaptation to Extreme Weather

Infrastructure demands foresight and a precise response to changing physical conditions. The JUMBO BLOCK system provides standardised, modular solutions that protect structures and support a resilient environment.

Engineered for exceptional durability and demanding loads, the system serves three core functions:

Retention: Controlled flow restriction and discharge. Water storage: Storage capacity for process water and firefighting supply. Infiltration: Nature-based water management on site.

Ready for Your Projects – JUMBO BLOCK in Implementation

System Benefits at a Glance:

Digital resilience: Sensors designed for KRITIS and NIS-2 requirements, enabling continuous monitoring of critical infrastructure. Real-time transparency: Digital recording and tracking of system data and water levels aligned with CRA requirements. Fully reversible: Modular, expandable, relocatable and fully removable – flexibility rather than permanent demolition. Physical mass: Approximately 5 tonnes of monolithic C40/50 concrete and around 16 m³ gross capacity per module. Structural integrity: 25 cm support cross-section for high structural load capacity. Scalability: Flexible configurations, from individual structures to large retention systems. Designed for maintenance: Fully accessible on foot, suitable for heavy machinery and easy to clean mechanically (without complex pipe flushing).

Environmental Protection

Integrated Water and Environmental Protection

Sustainable infrastructure requires decisions that balance economic and environmental priorities over the long term.

Our systems support the natural water cycle, help prevent overloading receiving waters and preserve local biodiversity through targeted infiltration and water-management strategies.

Defence Systems

Protective and Infrastructure Structures

Requirements for structural protection, stability and modular adaptability in modern infrastructure have never been higher.

JUMBO BLOCK-based Defence Systems provide robust physical protection using high-strength concrete and modular protective panels designed for sensitive sites and demanding security requirements.

Quick to assemble using suspended and interlocking systems. The required protection level determines the panel design.
