Stormwater Attenuation Tanks M2025
High-strength geocellular crates for underground stormwater storage, SuDS attenuation, soakaway systems and rainwater harvesting projects in Europe.
Stormwater Attenuation Tanks for Controlled Drainage
M2025 is developed for projects where stormwater needs to be collected, stored and discharged in a controlled way.
The modular tank structure helps reduce surface water runoff, manage peak rainfall and make better use of underground space in urban developments, car parks, roads, public areas and commercial sites.
For European drainage projects, M2025 can be used as an attenuation tank system, an infiltration or soakaway structure, or a rainwater harvesting tank depending on the wrapping method and project design.
High-Strength Geocellular Crates for Underground Storage
Each M2025 tank is built from lightweight geocellular storage crates that can be assembled on site into the required length, width and height. The open void structure provides high water storage capacity while keeping the system easy to handle, stack and install.
The modular crate format allows engineers and contractors to adapt the tank layout to the available excavation area, required storage volume, installation depth and load conditions.
- Modular geocellular crate design for flexible tank layouts
- High void ratio for efficient underground water storage
- Suitable for single-layer and multi-layer tank systems
- Side panels, top covers and connectors for stable assembly
- Designed for attenuation, soakaway and rainwater harvesting applications
M2025 Stormwater Crates: ECO and ULTRA Options

Intertek Tested Load Performance
For European customers, load performance and long-term reliability are key concerns. M2025 has been tested through international third-party testing, including Intertek compressive strength testing and creep testing.
In addition to third-party testing, we also use in-house compression testing equipment for batch quality checks. This helps us monitor production consistency and confirm that each batch meets the required load-bearing performance before shipment.
Vertical and lateral load performance review for project evaluation.
Long-term performance testing for underground stormwater storage applications.
Technical documents can be provided for qualified project review.

Applications for Underground Stormwater Management
M2025 can be used in a wide range of underground stormwater management projects where water needs to be stored below the surface without occupying valuable land.
Car Parks
Roadways
Commercial Sites
Industrial Sites
Public Parks
Sports Fields
Residential Projects
Urban Flood ControlFor trafficked areas, load conditions, cover depth and installation details should be reviewed by the project engineer according to local standards.
Attenuation, Soakaway and Rainwater Harvesting Applications
The same M2025 modular crate structure can be used for different stormwater applications depending on the wrapping material, site soil condition and drainage design.
| Application | Typical Wrapping | Function |
|---|---|---|
| Attenuation Tank | Geomembrane + protective geotextile | Temporarily stores stormwater and releases it in a controlled way. |
| Soakaway System | Geotextile | Allows stormwater to infiltrate into surrounding soil where ground conditions permit. |
| Rainwater Harvesting Tank | Waterproof geomembrane | Stores rainwater for later reuse in suitable non-potable applications. |
- Attenuation is usually selected where controlled discharge is required.
- Soakaway use depends on local soil infiltration capacity.
- Harvesting applications require suitable waterproof lining and system design.
Simple Installation with Complete Accessories
M2025 attenuation crates are supplied in a compact format and assembled on site. The system is designed for practical handling, quick crate installation and stable tank formation with matching accessories.
Side panels are used around the tank perimeter, top covers help create a flat upper surface, and plug connectors improve stability between crates. Installation details should always follow the project engineer's design, local regulations and site conditions.
Side PanelCloses the perimeter of the tank.
Top CoverCreates a flat upper surface.
Vertical PlugConnects stacked layers.
Horizontal PlugConnects adjacent crates.
Efficient Packing and Container Shipping
For importers and project suppliers, shipping efficiency is an important part of total cost. M2025 is designed with stackable components to reduce transport volume and site storage space.
Compared with bulky pre-assembled products, the unassembled crate format is more suitable for long-distance export shipment from China to Europe.
| Concern | M2025 Advantage |
|---|---|
| Freight cost | Compact unassembled packing |
| Site storage | Stackable components |
| Installation handling | Lightweight PP structure |
| Project supply | Suitable for full container shipment |
