Function

Tensar TriAx geogrid with its improved rib geometry and junction efficiency, greatly improves aggregate interlock and confinement – leading to improved structural performance of the mechanically stabilised layer.

Applications

Road & highways

Tensar TriAx geogrids are a proven solution for pavement reinforcement on road and highway projects and greatly extend the lifespan of the pavement. Geogrids reduce pavement thickness by up to a third without impacting performance, which lowers installation and maintenance costs. The system can be deployed quickly, making it ideal for building temporary access roads over soft ground or for heavy vehicle loads.

Railways

Railway geogrids improve bearing capacity on railway projects and stabilise the rail ballast and track bed, improving performance. They also limit the movement and displacement of the rail ballast so less maintenance is required over the lifetime of the railway line.

Using Tensar TriAx as part of your rail track solution can decrease the amount of foundation material required by up to 30%, delivering real cost savings in construction

Airport & heavy duty pavements

Tensar TriAx geogrids are used to build working platforms for airport pavements and hardstand areas, particularly where the ground is soft. Multiple layers form a stiff beam that spreads heavy loads over a larger area, reducing differential settlement. In some cases two or three layers of geogrids may be required.

Load transfer platforms

Tensar TriAx geogrids provide an alternative to poured concrete for load transfer platforms. Aggregate caps reinforced with Tensar TriAx geogrids can be used to cap foundations built over pile fields, transferring heavy loads to deep foundations. 

Advantages

The interlocking structure of a Tensar TriAx geogrid gives it greater strength and endurance. Its outstanding performance is supported by extensive traffic trials in the UK. Using triaxial geogrids also saves on costs in terms of sub-base and aggregate requirements.

Tensar TriAx geogrids triple the load capacity on road and highway projects. They are easily deployed and available nationwide. Tensar geogrids are cost-effective and have a proven performance record in New Zealand and Australia.

Installation

The installation of Tensar TriAx® geogrid is straightforward with the geogrid able to be rolled out directly over the subgrade having removed any major protrusions such as rocks or tree stumps. Typical road aggregates are used with Tensar TriAx® geogrids for constructing permanent roads and highways, working platforms and gravel raft foundations.
