Rainsmart Solutions Geo Cellular Soakaway Boxes for Urban Drainage
Growing impermeable surfaces across UAE and GCC cities leave stormwater with nowhere to go. Rainsmart Solutions geo cellular soakaway boxes create an underground void network that captures, stores, and releases rainwater back into the soil, cutting surface runoff and protecting infrastructure from flooding.
Efficient stormwater drainage for UAE and GCC urban landscaping. Ideal for car parks, roof gardens, and detention tanks with Rainsmart Solutions technology. We supply soakaway boxes and geo cellular drainage cells in modular stackable configurations to match any storage and infiltration requirement.
At Dutco Tennant LLC, our stormwater management systems, underground water storage systems, and rainwater harvesting system solutions to civil contractors and infrastructure developers across the UAE and GCC.
Efficient Water Flow Management
- Geo cellular drainage cells deliver over 95% void ratio, storing significantly more water per cubic metre than conventional gravel systems.
- Lightweight polypropylene construction reduces excavation depth and soil transport requirements on site.
- Stackable and interlocking modules create custom storage volumes without heavy machinery or complex civil works.
- Geotextile wrapping suits infiltration applications; impermeable liner wrapping suits retention and detention tank use.
- Compatible with car parks, roof gardens, podium slabs, sports fields, and landscaped areas across GCC developments.

- Suited to car parks, road shoulders, sports fields, and large-scale urban stormwater infrastructure
- Highest load-bearing capacity within the Rainsmart Solutions range
Ellipse Tank Modules
A compact underground water storage system for infiltration, retention, and detention in space-constrained urban and landscape settings.
- Configurable as soakaway, retention, or attenuation system to suit project drainage requirements
- Combines with Nero Drainage Cell for integrated sports field drainage and sub-surface irrigation
- Suitable for residential, commercial, and podium drainage across GCC developments
Nero Drainage and Pave Cells
A thin-profile drainage cell range covering subsurface lateral drainage and permeable paving applications across roof gardens, podium slabs, sports fields, and trafficked surfaces.
- 30mm Nero Drainage Cell provides a uniform sub-surface drainage blanket across horizontal and vertical installations
- 50mm Nero Pave Cell stabilises grass or gravel surfaces allowing rainwater to infiltrate into the stormwater management system below
- Both variants lightweight, easy to cut on site, and suitable for green roofs, podium gardens, car parks, and landscaped areas
Impermeable Liner and Geotextile Accessorie
Wrapping accessories converting geo cellular modules into sealed retention tanks or open infiltration systems.
- Impermeable liner retains stored water for controlled discharge or reuse
- Geotextile membrane prevents silt and fine particles from blocking the void structure
- Compatible with all STM and Ellipse tank module assemblies
Standout Features & Benefits
Minimal Excavation and Site Disruption
- Significantly smaller excavation footprint required compared to gravel-based soakaway systems
- Lightweight modules handled and installed without heavy plant or machinery
- Modular assembly avoids large concrete pours or precast tank craning operations
Adaptable to Any Site Layout
- Units stack and interlock into any plan shape, depth, or storage volume required
- Compatible with inspection ports, flow control units, and silt traps for complete system integration
- Suitable beneath trafficked surfaces, landscaped areas, roof gardens, and podium slabs
Sustainable Urban Drainage
- Supports groundwater recharge through controlled infiltration into surrounding soil
- Recycled polypropylene construction aligns with sustainable construction specifications
- Reduces surface runoff volumes lowering the load on municipal drainage networks
Long-Term Low Maintenance
- Geotextile wrapping keeps silt and debris out of the storage volume
- Flush-out points and inspection access ports allow periodic checks without excavation
- No moving parts or mechanical components across the entire soakaway boxes system
Application Area
Car Parks and Trafficked Surfaces
- STM tank modules manage stormwater runoff beneath car park slabs and paved surfaces
- High load-bearing capacity sustains performance under vehicle traffic without structural settlement
- Nero Pave cells provide a surface-level infiltration layer above the underground storage system
Roof Gardens and Podium Slabs
- Lightweight subsurface drainage across podium and roof garden build-ups
- Reduces waterlogging in planting zones while maintaining adequate moisture for root growth
- Suitable for green roofs across hotels, residential towers, and commercial developments
Underground Detention and Retention
- STM and Ellipse modules form underground water storage systems for stormwater detention and reuse
- Stored water discharged at a controlled rate prevents downstream flooding during peak rainfall
- Supports rainwater harvesting system requirements for irrigation and non-potable water reuse
Sports Fields and Landscaping
- Removes surface water from playing areas immediately after rainfall
- Sub-surface irrigation reserve reduces freshwater consumption on sports turf
- Suitable for football pitches, golf courses, and landscaped public areas across the GCC
FAQ
How do soakaway boxes function within a stormwater management system?
Soakaway boxes store excess rainwater temporarily and allow controlled infiltration or discharge, helping balance flow within a stormwater management system.
What role do geo cellular drainage cells play in drainage design?
Geo cellular drainage cells create underground void spaces that store and disperse water efficiently, improving drainage performance in urban and landscaped areas.
Can a drainage cell system be used for water reuse applications?
Yes, when combined with liners, a drainage cell setup can function as an underground water storage system for reuse in irrigation or non-potable applications.
Are soakaway boxes compatible with rainwater harvesting systems?
Yes, they integrate seamlessly with a rainwater harvesting system, allowing collected water to be stored, managed, or reused efficiently.
How flexible are geo cellular systems for different project layouts?
The modular nature of geo cellular drainage cells allows them to be configured into various shapes and depths, adapting easily to site-specific design requirements.
Do soakaway boxes support long-term drainage performance?
Yes, properly installed soakaway boxes maintain consistent performance over time, supporting efficient water flow and reducing the risk of surface flooding.
