TCS TechGrid BX biaxial geogrids are designed for ground stabilisation and reinforcement applications. Manufactured from polypropylene, they provide strength in both longitudinal and transverse directions for reliable soil support.
TechGrid BX geogrids are integrally formed biaxial structures produced through extrusion and stretching processes. This results in a robust geogrid with consistent strength in both machine direction (MD) and cross direction (CD).
They are used to improve load distribution, reduce sub-base thickness, and extend pavement life in civil engineering and construction projects. Typical applications include road and rail construction, hardstandings, working platforms, and soil stabilisation over weak ground.

FAQs
What is the main use of TechGrid BX geogrids?
They are used for soil reinforcement and stabilisation in roads, pavements, hardstandings, and platforms, improving load distribution and reducing aggregate needs.
How are the geogrids installed?
Rolls are laid directly onto the prepared ground, with overlaps according to site conditions. They should be covered with aggregate within one month of installation.
What is the lifespan of TechGrid BX geogrids?
When buried in natural soils with pH 4–9 and temperatures ≤25°C, they are expected to last a minimum of 50 years.
Are they resistant to soil chemicals?
Yes, polypropylene provides resistance to naturally occurring acids, alkalis, bacteria, and fungi.
Can TechGrid BX geogrids be used in multiple layers?
Yes, they can be installed in single or multiple layers depending on project requirements.
