1. What is the JUMBO BLOCK® system?
The JUMBO BLOCK® system is a modular, high-strength concrete solution designed for versatility. Installed directly beneath sealed surfaces, it provides a flexible, scalable, and sustainable approach to storing large volumes of water while supporting a wide range of applications.
2. How does the JUMBO BLOCK® system work?
Prefabricated concrete blocks are easily connected to form a stable and durable storage system. The system can capture, store, and release water in a controlled manner to prevent flooding and efficiently manage water resources.
3. Where can the JUMBO BLOCK® system be installed?
The system is versatile and can be installed in urban areas, rural regions, or sloped terrains. It adapts easily to local topography and environmental conditions, making it suitable for almost any location.
4. What is the storage capacity of the system?
Each JUMBO BLOCK® provides a storage capacity of 13.9 m³, allowing for efficient large-volume retention with fewer components and lower installation effort.
5. Is the JUMBO BLOCK® system environmentally friendly?
Yes. The system uses CO₂-reduced green concretes, sustainable and recycled materials, and reusable molds — conserving resources and minimizing environmental impact.
6. How durable is the system?
With its robust construction, the concrete blocks are highly resistant to environmental and mechanical stresses. The system is built for long-term durability and requires minimal maintenance.
7. What maintenance is required?
The system is low-maintenance. Occasional inspections and cleanings are typically sufficient to ensure optimal performance.
8. Can the system be customized for specific needs?
Yes. The JUMBO BLOCK® system can be configured in different layouts and arrangements to meet specific project requirements and adapt to varying site conditions.
9. How does the JUMBO BLOCK® system contribute to climate protection?
By reducing surface runoff and minimizing energy use for pumping systems, the system helps lower greenhouse gas emissions. It also aids in preserving natural ecosystems essential for carbon sequestration.
10. Is the system patented?
Yes, the JUMBO BLOCK® system is protected by patents and trademarks, highlighting its uniqueness in the market.
11. Are JUMBO BLOCK® modules designed for Extreme Loads?
Yes. The unique, patented design of our JUMBO BLOCK® modules allows them to achieve exceptional load capacity.
Their hollow, cube-shaped construction with reinforced corner columns — combined with our proprietary high-strength concrete mix — ensures maximum resistance to extreme forces.
This makes JUMBO BLOCK® a reliable and efficient solution for the most demanding infrastructure projects.
Understanding Load Class F 900
12. What means Load Class F 900 ?
Load Class F 900 is one of the highest load-bearing classes for covers, gratings, and manhole covers used in civil engineering. It signifies the ability to withstand extremely high traffic loads of up to 900 kN (equivalent to approximately 90 tons).
13. What does 900 kN mean?
The abbreviation kN stands for kilonewton, the unit of force. A newton is the force required to accelerate a one-kilogram mass by one meter per second. For Load Class F 900, this means the cover can withstand a vertical compressive force of 900,000 newtons, which is equivalent to a load from vehicles of up to 90 tons.
14. What are the Areas of Application for Load Class F 900
Due to their extreme load capacity, components in Load Class F 900 are only used in areas with very high wheel loads. These include, but are not limited to:
Airports: Runways, taxiways, and aprons
Ports: Container terminals and transshipment areas
Industrial zones: Surfaces with heavy-duty traffic
Motorways: Sections frequented by very heavy trucks
These components are designed for areas where normal traffic loads (like those on city streets) are far exceeded. For standard road traffic, a lower load class, such as D 400, is usually sufficient.
Summary
With its modular strength, large storage volume, and F 900 load capacity, the JUMBO BLOCK® system sets a new standard for sustainable, high-performance infrastructure solutions.
