Safety is critical when using mobile cranes, piling rigs and other heavy plant on construction sites – particularly over weak and variable ground. What’s needed is a safe working platform.
Tensar® TriAx Geogrids mechanically interlock with a well graded granular fill resulting in particle confinement which amongst other benefits increases the bearing capacity of the resulting Tensar mechanically stabilised layer or MSL. This allows heavier static loads from cranes or piling rigs to be carried or platform thicknesses to be reduced to cater for heavy rig loading.
Unpaved roads are a feature of construction sites around the world. But while they have to cope with extremely heavy loads, these working platforms often have to be sited on weak or variable ground.
That’s where Tensar’s geogrids, incorporating clever working platform design – and in particular the innovative TriAx®– can help reduce costs by mechanically stabilising granular materials very efficiently. When compacted over the geogrid, the granular particles project through the triangular apertures and are mechanically confined. This interlock, combined with the grid’s near-uniform 360 degrees stiffness creates an efficient stiff composite layer for a working platform or unpaved road.
In TensarPave and TensarSoil we’ve developed unique, powerful software to help design engineers produce stabilised pavement and reinforced soil retaining structure designs quickly and easily. We also use FEA Plaxis analysis for using TensarTech Stratum on Crane Hardstands.
TensarTech® Stratum™ Cellular Foundation Mattress System
When faced with soft foundation soils, where expensive piling and other deep ground foundation treatments are not viable, the TensarTech® Stratum™ System provides an alternative approach to mass excavation and stoning up of Crane Hardstand areas, delivering the potential for huge savings in cost and time.
Used when new working platforms are sited over weak Clays and Peats, the TensarTech Stratum System creates up to a 1.3m deep stiff foundation platform that mitigates the effects of differential settlement, reduces lateral spread and can increase bearing capacity to improve stability enabling accelerated fill placement.
