Tensar International produces a wide range of unique products. Tensar®SS Biaxial geogrids are manufactured using a punched and stretched process that produces a unique product with no artificial joints.
Tensar®SS Biaxial geogrids have been proven in full scale pavement trials to out perform any other commercially available geogrid in the world. It is an effective product to reduce pavement thickness with no loss of performance.
Typical Tensar® Biaxial SS Geogrid Applications
Rail tracks support in the ballast and/or in the capping
Access tracks

Building and foundation support.
Soft area access
Tailing capping
Load Transfer Platforms over Piles
Features & Benefits
Ground stabilisation and Pavement reinforcement
Proven history and performance both in Australia and around the World for ground stabilisation on road and highway projects
Utilising Tensar biaxial geogrids, granular pavement thickness can be reduced by up to 33% without performance or design life penalties, resulting in a reduction excavation, spoil and imported pavement materials.
Pavement design life can be greatly extended by incorporating Tensar biaxial geogrids, typically tripling design traffic carrying capacity of a similar depth pavement
Rapid deployment and excellent performance make Tensar biaxial geogrids ideal for building temporary access roads, especially when the subgrade is soft, heavy vehicle loads or quality fill is scarce.
Railways
Tensar biaxial geogrids can be used in several locations in railway formations. Tensar biaxial geogrids used in the capping layer provide reinforcement in the lower layers, improving the bearing capacity and reducing treatment of excessively soft areas.
Tensar SSLA (large aperture) biaxial geogrids stabilise the rail ballast and track bed, improving the performance and possibly reduces track bed thickness. Utilising Tensar SSLA geogrids in the ballast layer extends the life between re-ballasting and tamping operations by limiting the movement and displacement of the rail ballast.
Accessing very soft areas
Construction of roadways and developments often traverse through soft or waterlogged ground causing many access and construction problems. These areas include very soft mud and clays, peat or tailings deposits. Tensar biaxial geogrids perform like a “snow-shoe” providing immediate support to construction activity in the initial fill layers and allowing effective compaction, expediting construction and reducing fill requirements.
Reduction in differential settlements
Multiple layers of Tensar SS biaxial geogrids can be utilised to construct working platforms that can significantly reduce differential settlements, useful for airport pavements, hardstand areas and foundations, especially over soft subgrades.
Multiple layers of Tensar SS biaxial geogrids create a stiff beam within the aggregate layer by confining the aggregate, effectively spreading the imposed loads over a larger area and creating a monolithic structure, reducing differential settlement.
Capping application
Tensar biaxial SS geogrids enable safe, rapid placement and compaction of fill in capping of very soft sludge lagoons and industrial waste deposits.
Load transfer platforms
The effective confining action of the Tensar SS geogrids allows use in pile caps and load transfer platforms. As an alternative to traditional poured concrete, aggregate caps reinforced with Tensar biaxial geogrids can be used to cap foundations of structures built over pile fields efficiently transferring the imposed loads to the deep foundations.
The Tensar Load Transfer Platform (LTP) is a layer of high quality granular fill reinforced with Tensar biaxial geogrids. The LTP provides a stiff layer that transmits load directly from an embankment or pavement formation to the supporting foundations below. Based on model foundation testing, the effective load spread of a granular layer reinforced with Tensar biaxial geogrids can conservatively be taken as 45º.
Heavy duty pavements
In applications where the foundation is soft and heavy loading is expected, multiple layers of Tensar geogrid may be required. Multiple layers of Tensar SS biaxial geogrids create a stiff beam within the aggregate layer by confining the aggregate, effectively spreading the imposed loads over a larger area, reducing the imposed loading on the subgrade, improving the performance of the pavement by allowing heavier loading or reduced pavement thickness. In such cases two or possibly three layers of geogrid may be required to efficiently spread the load over wider areas.
