Benefits and Magic The JUMBO BLOCK® System A grid of hollow giants holding 13.9 cubic meters each.

Why Choose the JUMBO BLOCK® System?


  • Effective & Cost-Efficient: Avoid costly flood damage with a proactive solution that reduces repair and recovery expenses over time.


  • Inconspicuous Design: Installed underground, the system preserves the natural landscape and existing infrastructure, leaving the surface fully usable.


  • Unmatched Load Capacity: Class F 900 or even more. This makes JUMBO BLOCK® the ultimate solution for heavily loaded infrastructures such as airports, industrial plants and container terminals.


  • Massive Water Storage: Designed to handle extreme rainfall events, each block provides significant water retention, making it a vital resource for regions prone to flooding.


  • Durability & Low Maintenance: Built from high-grade concrete, the system offers exceptional durability and requires minimal maintenance, ensuring long-term performance and reliability.


  • Sustainable Solution: By reducing urban flooding and promoting natural water cycles, JUMBO BLOCK® protects both communities and ecosystems. Additionally, the use of eco-friendly materials and recycled resources supports a sustainable construction process.


The JUMBO BLOCK® System – Maximizing Water Retention Without Sacrificing Land

The JUMBO BLOCK® System – Maximizing Water Retention Without Sacrificing Land


Our system creates large underground retention areas without sacrificing valuable surface land or harming the environment. This approach ensures that urban spaces remain usable for roads, parking lots, or green areas, while underground, a powerful water management solution is at work.


The unique design and large size of the JUMBO BLOCK® hollow blocks enable the effective storage of vast volumes of water. This water can either infiltrate naturally into the ground or be repurposed for irrigation, cooling, or flood protection, offering maximum flexibility and sustainability.


Powerful Data & Key Metrics


  • Capacity: Each block stores an impressive 13.9 m³ of water, ensuring significant water retention with fewer components.


  • Water Column Per Block: Each JUMBO BLOCK® supports a water column of 2224 liters per m², providing exceptional flood protection capacity.


  • Total Volume of a System: The system's total capacity is determined by the number of installed blocks, allowing for customized, scalable solutions tailored to specific project needs.


With its modular, scalable, and sustainable design, the JUMBO BLOCK® system addresses modern flood protection challenges, offering a reliable, cost-effective, and eco-friendly solution for urban, rural, and industrial applications.
