TENAX - Model 3D Grids -Stabilisation of Soils
TENAX’s 25 years experience has confirmed that stabilisation of soils is an extremely cost effective method of converting areas of weak soil into a usable and environmentally sound construction material. Combining the use of TENAX bi-oriented geogrids with soils to create a much improved grid/soil composite has meant that many soils found on site can be improved cost-effectively for applications in: Roads, Railways, Airfields, Reinforced earth structures e.g. for walls and steep slopes, Container ports, Working Platforms for rigs and other heavy plant.
By reinforcing the granular base layers with TENAX geogrids, construction can be carried out cost effectively, quickly and with less environmental impact due to reduced excavation depths (up to 40% less), less disposal of material from site and an overall reduction in the use of natural aggregates.
Rising landfill and aggregate costs together with environmental considerations have made the application of TENAX bi-oriented geogrids a must for all contractors. The range of successful ground stabilisation projects covers a broad spectrum from high profile sites such as the Olympics, European Main Line Railways, Highways and Airports to smaller sites like sports pitches, small housing projects and single track roads.
Maximising interlocking
When granular material is compacted over TENAX LBO geogrids, stone particles partially enter the apertures of the grid and are eventually "locked-in" to create a strong and positive interlock along the plane of the geogrid.
This key interlocking mechanism enables the grid to resist horizontal movement of the stones which improves the performance of the pavement and provides a high degree of control on settlements.
This concept has led the TENAX Research & Development team to manufacture and develop a new innovative range of 3-Dimensional Geogrids that aim to maximise the interlocking within the soil or stone / grid matrix.
Greater lateral confinement
TENAX 3D Grids products have been developed with the aim of allowing the most efficient use of reinforcement in the most challenging environments.
The performance benefits now go beyond TENAX bi-oriented geogrids and provide even more cost effective designs.
In addition to the high mechanical characteristics provided by the bi-oriented range, TENAX 3D Grids have been designed to produce a greater lateral resistance. The result is a revolutionary new geogrid system that is able to act through a wider cross section of soil thereby creating a true grid/soil composite material.
