The TCS Tensar SS Series biaxial geogrid is designed for soil reinforcement and aggregate stabilisation in civil engineering and construction projects. Available in SS20, SS30, and SS40 grades, these geogrids provide long-lasting ground support for pavements, working platforms, and foundations.
Tensar SS geogrids are stiff, monolithic grids with integral junctions, orientated in two directions to deliver balanced strength and stability. The biaxial rib structure interlocks with aggregate, controlling lateral movement and distributing loads efficiently across weak or variable soils.
Typical Benefits
- Reduced aggregate thickness and excavation
- Faster, more economical construction
- Improved bearing capacity and surface stability
- Control of settlement and rutting
- Long-term chemical and biological resistance
Common Applications
- Highways, access roads, and car parks
- Temporary crane and piling platforms
- Rail track beds
- Airport runways and aprons
- Coastal and river defence bunds
- Waste management and landfill capping
- Ground stabilisation over weak subgrades

Installation Notes
- Lay directly on prepared subgrade after removing sharp protrusions

- Avoid trafficking directly on uncovered geogrid
FAQs
What is the difference between SS20, SS30, and SS40?
The numbers refer to tensile strength (20, 30, and 40 kN/m respectively). Higher grades are suited to heavier load and more demanding applications.
Can Tensar SS geogrids be used under permanent structures?
Yes, they are commonly used under roads, railways, and foundations where long-term reinforcement is required.
How are rolls joined on site?
Overlaps of 300–600mm are used, depending on soil and subbase stiffness. Small heaps of fill help maintain overlaps during installation.
Do I need specialist equipment for installation?
No, standard site machinery (excavator, dozer, roller) is sufficient. Heavy duty gloves are recommended for handling.
Are these geogrids resistant to chemicals in soil?
Yes, they are inert to naturally occurring soil chemicals and resistant to acids, alkalis, and salts.
