About Geocell 200-445 – Technical Design Overview
InfraCell 200-445 – Technical Design Overview
Product Overview
InfraCell 200-445 is a high-performance HDPE geocell engineered for heavy-duty applications such as haul roads, crane platforms, and other high-load construction environments. Its cellular confinement structure distributes applied loads over a wide area, improving performance on weak subgrades and reducing rutting under heavy traffic.
Serviceability & Strength Design Guidance
Load Capacity
InfraCell200-445 (200mm cell depth, 445mm weld spacing) is designed to handle up to 60,000 kg gross vehicle weight (GVW) per vehicle, making it suitable for:
-
Dump trucks (30–50 tonnes)
-
Heavy construction vehicles
-
Crane and piling rigs
Key Performance Attributes
-
Cell depth: 200 mm – deep enough to resist significant shear and reduce vertical deformation under wheel loads
-
Weld spacing: 445 mm – optimized for load distribution and soil confinement
-
Recommended subgrade: Typically installed over a geotextile separation layer to prevent mixing of base soils and infill
-
Infill options: Well-graded granular material or engineered fill compacted in layers
-
Slope and drainage: Suitable for gentle grades up to 10%; effective lateral restraint prevents downslope movement in haul roads with minor incline
Typical Application Matrix
| Cell Depth | Gross Vehicle Weight (GVW) | Typical Applications |
|---|---|---|
| 50 mm | < 500 kg | Landscaping, green roofs, walking paths |
| 75 mm | < 1,000 kg | Pedestrian & cyclist paths, light-duty carports, school playgrounds |
| 100 mm | < 3,000 kg | Domestic driveways, residential roads, private carports |
| 100–150 mm | < 9,000 kg | Commercial parking, delivery zones, car parks |
| 150 mm | < 16,000 kg | Emergency access lanes, agricultural access for tractors and larger vehicles |
| 150–200 mm | < 30,000 kg | Construction sites, access for refuse and service vehicles |
| 200 mm | < 60,000 kg | Heavy construction traffic, HGVs, cranes, piling rigs – including haul roads |
Installation Best Practices
-
Geotextile base layer: Recommended under the geocell for separation and filtration
-
Anchor spacing: Every 1–1.5 m depending on slope and traffic
-
Compaction: Achieve ≥ 95% modified Proctor density for optimal performance
-
Infill: Typically crushed rock, engineered fill, or lateritic soil
Site-Specific Design
While this guide provides general serviceability parameters, final design (e.g., layer thickness, CBR consideration, stress analysis) should be confirmed by a qualified civil engineer. For engineering design support, we recommend Empire Engineering or an equivalent geotechnical consultant.
