The TensarTech® Stratum™ Cellular Foundation Mattress System (formerly known as TensarTech Geocell Mattress System) has been used successfully in embankment foundation applications since it was introduced in 1983. A continuous open cellular structure, the Tensartech Stratum System is typically 1 m thick, comprising Tensar uniaxial and TriAx® geogrids.
3 MAJOR BENEFITS WHEN USING TENSARTECH® STRATUM™ :-
1. Reducing Ballast Deformation through the Mechanical Stabilisation of the Ballast Layer
The TensarTech® Stratum™ System can provide initial construction access onto soft sites and is rapid to assemble. Once filled with coarse gravel, it acts as a stiff platform that provides a stiffened foundation for the embankment allowing even and controlled settlement.
2. Improve and Increase Stability
The TensarTech Stratum System intersects potential failure planes. The rigidity of the cellular foundation mattress system forces the planes deeper into the firm strata below. The critical failure mechanism then becomes that of plastic failure of the soft layer and the stability can be improved.
3. Reduce Lateral Spread
The rough interface at the base of the TensarTech Stratum System reduces lateral spread and also ensures mobilisation of the maximum shear capacity of the foundation soil further increasing stability.
