For details of Tensar workshops visit www.tensar-international.com 4 Ground Stabilisation There are now unprecedented demands to design economic and environmentally sensitive roads, container ports, car parks, airfields and hardstandings sited over weak or variable ground. Tensar geogrids give a high performance solution which also meets these demands. The structural contribution made by Tensar TriAxTM geogrids is to reinforce the unbound layers of roads and trafficked areas to create a mechanically stabilised layer. Aggregate particles interlock with the geogrid and are confined within the apertures,...

5 TriAxTM enables significant savings in granular thickness and consequent reduction in construction CO2 emissions. Particle interlock and the mechanism of confinement enhances compaction over weak ground. Granular layer Unreinforced Mechanically stabilised layer TriAxTM geogrid Constructions having equivalent performance The reduction in aggregate materials and transportation helps engineers meet sustainability objectives. TriAx™ A REVOLUTION IN GEOGRID TECHNOLOGY Proven performance - in trafficking trials TriAxTM outperforms Tensar biaxial geogrids Reduces aggregate - providing cost savings,...

The major ground Reducing layer thickness Numerous research programmes over the years have consistently proven the high stabilisation factors attributed to Tensar geogrids. With the improved performance from Tensar TriAxTM geogrids, Tensar Technology now offers even greater reductions in aggregate. Choosing the ground stabilisation solution for your project Since Tensar introduced stiff polymer...

7 stabilisation applications for Tensar Technology Increasing life The use of Tensar TriAxTM geogrids in pavement layers can extend the service life of the road and therefore the use of Tensar Technology makes significant savings in maintenance budgets. Increasing bearing capacity By applying Tensar Technology the load spreading capability of a Tensar TriAxTM stabilised layer can increase the bearing capacity of working platforms for heavy-duty plant, cranes and piling rigs. Controlling differential settlement Multiple layers of Tensar TriAxTM geogrids in an aggregate layer create a flexurally...

Tensartech Systems for Earth Retaining Slopes can shorten construction times and minimise traffic disruption. For details of Tensar workshops visit www.tensar-international.com 8 The Tensartech GreenSlope is designed for building soil structures with a sloped face of up to 70¢ª. The facing consists of durable steel units connected to the geogrids using Tensar’s highly...

secondary reinforcement primary reinforcement establishment of vegetation and long-term erosion protection Tensar’s proven geogrids reinforce the soil mass providing long-term stability. Tensartech NaturalGreen can provide a durable, cost-effective and attractive flood defence. Quick and efficient repair of soil embankments or cuttings 9 Tensar geogrids can be used to provide a quicker, cost effective and more environmentally friendly alternative to the customary techniques for slip repair. Traditionally these would involve the excavation and off site transportation of failed fill material. Replacing...

A feature common to all Tensartech Wall Systems is the high efficiency of the connection between geogrid and the chosen facing, in this case the TW1 Wall System. Tensartech Wall Systems such as this TW1 are suitable for the most demanding applications and are versatile enough to accomodate both technical and aesthetic consideration. Tensartech Earth Retaining Systems for Wall and Bridge Abutments ¡ Long-term design stability using proven, independently certified products and systems ¡ Simply constructed solutions to reduce build times and resulting costs ¡ An aesthetically appealing end result...
