Municipalities and street retention must adapt to extreme weather events to ensure resilience and sustainability. "Cities must not fight against water—they must learn to live with it, because it is not the strongest who survive, but those who adapt to change." Inspired by Charles Darwin


"Extreme weather is no longer a distant threat—it is here."

Municipalities and Street Retention

Utilizing Technologies for Adaptation


Weather extremes, urbanization, and global trends present new challenges that demand innovative solutions. 

We can leverage and develop technologies to secure a sustainable future:


Water Storage and Adaptation

Implementing technologies to manage water storage and adapt to extreme weather events.


Energy Efficiency and Sustainable

Advancing measures and technologies to enhance energy efficiency and promote sustainable practices.


By embracing these challenges, we pave the way for a future that is sustainable and livable for everyone!

JUMBO BLOCK ® Straßenretention ist eine revolutionäre Technologie zur Regenwasserrückhaltung.

An Innovative Solution

Flood Protection and Water Storage


JUMBO BLOCK® street retention offers a revolutionary approach to managing rainwater beneath our roads. This technology not only provides effective flood protection but also supports water storage and reuse.


Flexible and Adaptable


The JUMBO BLOCK® system is designed for flexibility and adaptability, making it suitable for deployment in a wide range of areas and conditions, including historic old towns.

Street retention to protect values, infrastructure, and the population.

Transforming Rainwater from a Problem into a Valuable Resource

Flood Protection and Water Storage


Large-volume hollow blocks beneath the road surface effectively store or infiltrate rainwater, reducing flood risks and ensuring sustainable environmental protection.


Intelligent Water Management


IoT water level sensors offer real-time data on water levels, turning the system into an intelligent flood protection tool and a crucial resource for informed water management decisions.


Sustainable Irrigation


Stored rainwater can be repurposed for irrigating green spaces or other uses, promoting sustainable water practices.

There is no bigger system! JUMBO BLOCK ® in modular construction.

JUMBO BLOCK® Solution

JUMBO BLOCK® Components

1️⃣ JUMBO BLOCK®
The core of the system – a massive, hollow, load-bearing concrete module (2.5 m x 2.5 m x 2.5 m) with an impressive capacity to support up to 792 tonnes. This block is designed for underground installation, forming the backbone of a modular and scalable retention system.


2️⃣ Sedimentation and Filtration Inside the Block
The built-in filtration system captures sediments and impurities within the JUMBO BLOCK® itself. This design prevents clogging and extends the lifespan of the system, while maintaining a continuous water flow.


3️⃣ Heavy-Duty Cover Plate
The cover plate provides an ultra-strong, load-bearing surface above the JUMBO BLOCK®. It enables heavy-duty applications like roads, airport runways, and industrial sites, while ensuring surface stability and protecting the system below.

A System of strength

4️⃣ Side Plate
Side plates are installed to enclose the JUMBO BLOCK® modules on the sides, preventing lateral water movement and ensuring system integrity. They help stabilize the overall structure and protect against shifting forces.


5️⃣ Base Plate
The base plate provides a stable foundation for each JUMBO BLOCK®, distributing the weight evenly and creating a secure, level base. This feature is essential for ensuring structural stability and longevity.


6️⃣ Sealing System
The sealing systems for JUMBO BLOCK® provide durable, waterproof solutions for module connections. Using high-performance adhesives and sealants, they securely seal joints and connections, preventing water loss and optimizing retention efficiency. Their flexible, durable materials ensure long-term functionality under varying conditions.

Implementation

What scientific experts say about adaptation:

"The thing about climate change is that both the Earth's ecosystem and human settlements and infrastructure are highly adapted to what the climate has been like over the past centuries. Therefore, any form of change—whether global warming or cooling—is always negative because it leads to poor adaptation. Take the massive floods we have experienced almost every week somewhere in the world over the past months. If this had been the norm for centuries, rivers and sewage systems would be adapted to handle such water. But because we are not accustomed to it, disasters occur. That is the problem with climate change."


Stefan Rahmstorf, Potsdam Institute for Climate Impact Research

We cannot stop the rain, but we can control where it flows!

"Problems can never be solved with the same mindset that created them." — Albert Einstein

We cannot stop the rain, but we can control where it flows. Large-scale retention systems, like JUMBO BLOCK®, are a direct solution to a physical challenge. Water cannot simply disappear – it must be absorbed, stored, and safely redirected to prevent damage. This is not magic; it’s the result of physics and engineering.


Adaptation is not a sign of surrender, but a mark of understanding. It is the next step for a species that has learned to redirect rivers, build cities, and innovate technologies. Refusing to respond to reality is to ignore the fundamental trait that defines us as humans: our ability to solve problems and adapt.
