Design with EcoBloc Inspect SMART.
Plan an underground stormwater reservoir around your required storage volume, site footprint and long-term inspection needs. Explore the specifications, layout process and compatible components for GRAF EcoBloc Inspect SMART.
One module. Flexible underground storage.
GRAF EcoBloc Inspect SMART modules click together to form an underground reservoir sized around your site. Their open internal structure delivers approximately 203 litres of usable storage per module and includes channels for planned inspection and cleaning.
- Configure length, width and permitted stack height to suit the engineered layout.
- Plan access for camera inspections and suitable high-pressure cleaning.
- Use compatible baseplates, end plates, connectors and access components.
- Select permeable or impermeable containment to match the application.
Module gross volume: 211 L. Listed height excludes the separately supplied 40 mm baseplate.
From drainage requirements to a buildable layout.
Use this five-step process to organize the information your engineer and the BARR stormwater team need for a preliminary EcoBloc Inspect SMART configuration.
Calculate the storage volume
Determine the design rainfall, contributing area, runoff characteristics, allowable discharge and resulting storage requirement under applicable local criteria.
Map your site constraints
Confirm the available footprint, nearby services and structures, grades, required setbacks, groundwater conditions and excavation limits.
Configure the modules
Choose a preliminary footprint and number of layers. Allow space for baseplates, access shafts, pipes and any required construction clearances.
Review loads and containment
Check anticipated traffic, minimum and maximum cover, soil support, water table, pretreatment and the appropriate liner or geotextile system.
Finalize system details
Coordinate inlet and outlet connections, overflow, inspection access, maintenance provisions and the engineered installation specification.
Estimate modules from the required storage volume.
Use the standard module's nominal usable storage as an early planning figure. Final system capacity must account for the complete assembly.
= preliminary number of modules (round up)
Worked example: 100,000 L ÷ 203 L = approximately 493 modules. A conceptual 25 × 10 × 2 layout uses 500 modules and provides 101.5 m³ of module-only nominal storage.
This is not an engineered sizing tool. Baseplates, connections, construction allowances and applicable design factors affect the final layout and usable storage.
Illustrative geometry only. Not an installation drawing or a confirmation of an acceptable structural arrangement.
Choose the right water-management function.
The same Inspect SMART module can serve different underground storage objectives. Your design determines the containment, pretreatment, connection and maintenance requirements.
Stormwater infiltration
A suitably permeable geotextile assembly permits stored runoff to infiltrate into surrounding soil when confirmed soil conditions and local regulations allow it.
Permeable containmentStormwater detention
An engineered impermeable containment assembly temporarily stores runoff and releases it through a controlled outlet. Include overflow and access in the hydraulic design.
Watertight containmentRainwater harvesting
A suitably lined reservoir can hold collected rainwater for reuse. Account for filtration, water quality, pump access and the intended end-use in the system design.
Storage for non-potable reuseWhat to verify before finalizing your design.
These checks influence whether a proposed footprint, number of layers and installation arrangement are suitable for your project.
Earth cover & burial depth
Check minimum and maximum cover, finished grade, excavation depth and any construction-stage loading against the current manufacturer instructions for part 402500.
Surface & traffic loads
Identify pedestrian, landscape, parking or roadway conditions. Review traffic classes, load distribution and temporary machinery loads with the engineer.
Groundwater & soil conditions
Confirm bearing capacity, groundwater fluctuations, buoyancy, groundwater separation and soil infiltration performance, where applicable.
Footprint & nearby infrastructure
Coordinate reservoir setbacks, adjacent foundations, utilities, structures, pipe gradients and access for excavation equipment.
Connections & pretreatment
Coordinate inlet and outlet elevations, peak inflows, hydraulic controls, overflows, sediment pretreatment and approved pipe connections.
Inspection & maintenance
Position access shafts so inspection cameras and appropriate cleaning equipment can reach the intended channels. Establish an ongoing maintenance plan.

EcoBloc Inspect SMART design FAQs
Common preliminary questions about sizing, applications, layout and long-term maintenance.
How many EcoBloc Inspect SMART modules will I need?
For a preliminary quantity, convert the storage requirement to litres and divide by the standard module's nominal 203 L usable storage, then round up. Confirm the final count using the complete engineered system, including baseplates, access structures and any relevant design allowances.
Can EcoBloc Inspect SMART be installed beneath a parking area?
It can be used in suitable engineered vehicle-loading applications. The structural design must account for actual traffic loads, soil conditions, construction loads, cover depth and the limits specified in the current manufacturer installation instructions.
Can the same module be used for infiltration and detention?
Yes. The module provides the underground storage structure. An infiltration design uses an appropriate permeable geotextile assembly where site conditions permit. A detention design requires an engineered impermeable containment assembly and a controlled outlet.
Can the reservoir be inspected and cleaned after installation?
Inspect SMART has internal inspection channels. Appropriate access shafts and a coordinated layout let maintenance crews use suitable camera inspection and high-pressure cleaning equipment. Include upstream sediment pretreatment and a site-specific maintenance plan.
What is the difference between module volume and installed system capacity?
A standard 402500 module has 211 L of gross volume and approximately 203 L of nominal usable storage. The final system also includes baseplates and other components. Use approved drawings and hydraulic calculations to establish the actual completed reservoir capacity.
What should I send BARR for a preliminary design review?
Start with a project location, site plan, required storage volume, intended application and approximate construction date. Include proposed cover depth, traffic loading, drainage calculations and geotechnical information if they are available.
