TCS Tensar SS Series Biaxial Geogrid Reinforcement Mesh

TCS Tensar SS Series is a biaxial polypropylene geogrid designed for long term soil reinforcement and aggregate stabilisation. It is a permeable, monolithic grid with integral junctions, providing equal tensile strength in both longitudinal and transverse directions.

When installed within granular layers, the SS geogrid interlocks with aggregate particles to control lateral spread and distribute applied loads more evenly into the sub grade. This improves bearing capacity, reduces surface deformation and helps control settlement and rutting, particularly over weak or variable soils.

Tensar SS geogrids are widely used in road construction, car parks, working platforms, rail formations and foundations. They are also specified for heavy duty applications such as crane pads, piling platforms, airport pavements and infrastructure projects where consistent long term performance is required.

By improving load transfer, Tensar SS can reduce excavation depth and sub base thickness compared to unreinforced designs. This can lower material volumes, speed up installation and reduce overall build costs, especially on poor ground.

Installation is straightforward. The geogrid is laid directly onto a prepared sub grade, typically above a non woven geotextile membrane where separation is required. Overlaps are formed in accordance with ground conditions and the grid must be covered within 30 days to maintain design life.

The SS range is available in three strength grades to suit different loading and ground conditions.

• Biaxial reinforcement with balanced strength in both directions
• Controls aggregate movement and improves bearing capacity
• Reduces sub base thickness on weak soils
• Stiff, monolithic grid with integral junctions
• Resistant to chemical and biological attack in soil
• Suitable for permanent civil engineering applications

Tensar SS geogrids are manufactured from extruded polypropylene with a minimum of 2% carbon black. This provides resistance to UV exposure during installation and long term durability when buried in soil.
