Tensar TriAx Geogrids
Tensar TriAx stabilises granular layers through interaction between the geogrid and aggregate. We supply and install the system beneath roads, working areas and other engineered surfaces to help build reliable support over the subgrade.

Installation and technical guidance
Design and procurement inputs
Select the product for the actual function: aggregate stabilisation, soil reinforcement or combined separation and reinforcement. Confirm aggregate compatibility, subgrade conditions, loading and the approved layer build-up.
Provide the product grade or performance specification, drawings or BOQ, quantities, site location and required date. We will define supply, delivery and any agreed installation and QA/QC responsibilities in the quotation.
Request a product-specific quotation →Installation and QA/QC
Record roll identity, reinforcement direction and location, joints, connections, fill placement and the specified compaction controls.
Use the current supplied-product procedure and the approved project inspection plan. Define responsibilities and acceptance criteria before installation.
SELECTION · SPECIFICATION · PROJECT SUPPLY
Choose the right specification
Separate aggregate stabilisation from designed tensile soil reinforcement before choosing a grid or composite.
- For stabilisation, define subgrade, aggregate, traffic or working load and permitted deformation.
- For walls, slopes and basal reinforcement, obtain the required long-term design strength, geometry and interfaces.
- Confirm grade, orientation, joint or connection details and any separation or filtration layer.
Define the quality records
Record roll identity, reinforcement direction and location, joints, connections, fill placement and the specified compaction controls.
For a useful quotation: send the grade or performance specification, quantity, location, required date and scope. Availability, delivery and installation responsibilities are confirmed in the quotation.
