Classification of Geogrid
Geogrids can be categorized based on their structure, material, and application. TYNOD offers several main types to meet different engineering demands:
Uniaxial Geogrid
Uniaxial geogrid is stretched in one direction, providing high tensile strength along the longitudinal axis. It is primarily used in applications requiring reinforcement in a single direction, such as:
Retaining walls and steep slopes
Embankment reinforcements
Soil retaining structures
Its strong tensile capacity and low creep performance make it ideal for structures that need long-term load-bearing reinforcement.
Biaxial Geogrid
Biaxial geogrid is stretched in both longitudinal and transverse directions, providing balanced strength in two directions. It is widely used in:
Road base and subgrade reinforcement
Airport runways and railway foundations
Parking lots and industrial yards
The bidirectional tensile strength helps improve the load distribution of subgrade soils, reduce deformation, and extend the service life of pavement structures.
Triaxial Geogrid
Triaxial geogrid has a unique triangular structure that provides multi-directional strength. Compared to traditional biaxial geogrids, triaxial types offer superior performance in load distribution and stability, especially under dynamic or heavy traffic conditions. Typical applications include:
Highways and heavy-duty pavements
Railway subgrade reinforcement
Areas with weak soil or high settlement potential
Fiberglass Geogrid
Fiberglass geogrid is made from high-strength glass fiber coated with bitumen or PVC to improve durability. It is mainly used for:
Asphalt pavement reinforcement
Crack resistance and reflective crack control
Extending the life of road surfaces
Fiberglass geogrids are stable at high temperatures, resist creep, and bond well with asphalt layers.
Polyester Geogrid
Polyester (PET) geogrid is woven from high-strength polyester yarns and coated for protection. It provides excellent flexibility, high tensile strength, and low elongation, making it suitable for:
Soft soil reinforcement
Subgrade stabilization
Embankment and retaining wall structures
PET geogrids offer good chemical resistance and are particularly effective in environments with aggressive soils.
Biaxial geogrid provides balanced tensile strength in both directions, typically ranging from 20–50 kN/m, effectively improving soil stability, load distribution, and ground reinforcement performance.
Uniaxial geogrid delivers high tensile strength mainly in one direction, typically 40–300 kN/m, ideal for retaining walls, slopes, and embankment reinforcement applications.
Triaxial geogrid offers multi-directional strength with tensile range 20–60 kN/m, enhancing soil stability, load distribution, and pavement performance under heavy traffic conditions.
Fiberglass geogrid features tensile strength from 30–200 kN/m, excellent creep resistance, and high-temperature durability, widely used for asphalt pavement reinforcement and cracking prevention.
Polyester geogrid provides tensile strength from 20–400 kN/m, excellent creep resistance, and chemical stability, widely applied in soil reinforcement, slopes, and retaining wall structures.
Applications of Geogrid
Geogrids are versatile materials that play a critical role in modern infrastructure. Their primary function is to improve soil behavior, increase stability, and extend the life of structures. TYNOD geogrids are widely used in the following fields:
Road and Railway Construction
Geogrids are extensively used to reinforce subgrades and pavement layers in roads, highways, and railways. By distributing loads and reducing differential settlement, they minimize rutting, cracking, and maintenance costs. Applications include:
Base course reinforcement
Subgrade stabilization on weak soils
Reducing asphalt layer thickness while maintaining performance
Retaining Walls and Steep Slopes
Uniaxial and polyester geogrids are commonly used to reinforce soil behind retaining walls, embankments, and steep slopes. They enable the construction of mechanically stabilized earth (MSE) structures with higher stability and lower material costs than traditional concrete walls.
Airport Runways and Heavy-Duty Platforms
For airports, container yards, and industrial platforms subject to heavy loads, biaxial and triaxial geogrids offer excellent load distribution and resistance to deformation. This ensures long-term performance even under continuous dynamic loading.
Landfills and Environmental Projects
Geogrids can be combined with geomembranes or geotextiles to stabilize landfill liners, cover systems, and slopes. They prevent slippage, improve stability, and help maintain the integrity of containment structures.
Soft Soil Stabilization
In areas with weak or saturated soils, geogrids provide additional tensile strength to support loads, control settlement, and improve overall stability. Polyester and biaxial geogrids are often used for these applications.

Manufacturing Process and Quality Assurance
At TYNOD, we understand that the performance of geogrids depends heavily on the quality of raw materials and manufacturing precision. Our geogrids are produced using high-grade polyethylene (HDPE), polypropylene (PP), fiberglass, or polyester (PET), selected for their strength, chemical resistance, and durability.
The production process involves extrusion, punching, and stretching to create a grid structure with uniform openings and excellent tensile properties. For uniaxial and biaxial geogrids, the polymer sheets are stretched in one or two directions to achieve the desired strength. Triaxial geogrids are manufactured using advanced molding and orientation techniques, resulting in a unique triangular mesh pattern that distributes loads more effectively.
Fiberglass and polyester geogrids undergo weaving and coating processes to ensure high bonding strength and enhanced resistance to environmental factors. All products are subject to strict quality inspections, including:
Tensile strength and elongation testing to verify mechanical performance.
Creep resistance tests to ensure long-term stability under continuous loading.
Chemical resistance and UV exposure tests to guarantee durability in harsh environments.
Dimensional accuracy checks to maintain uniformity and consistency across production batches.
Our factory adheres to ISO quality management systems, and many of our products comply with international geosynthetics standards, ensuring reliability for both domestic and overseas projects.
Installation Guidance and Best Practices
The effectiveness of geogrid reinforcement depends not only on product quality but also on proper installation. TYNOD provides detailed technical support and guidance to ensure optimal performance in the field. Key installation steps include:
Surface Preparation
The subgrade must be leveled and cleared of debris, roots, or sharp objects that could damage the geogrid. Soft areas should be properly compacted or stabilized before placement.Geogrid Placement
The geogrid is unrolled in the required direction (uniaxial for longitudinal reinforcement, biaxial/triaxial for two-way reinforcement). Adjacent rolls are overlapped according to design specifications, usually 200–400 mm, and connected with clips, ties, or staples to maintain alignment.Tensioning and Fixing
Proper tensioning is essential to eliminate wrinkles and ensure full soil contact. Anchor pins or stakes are used to secure the geogrid in place, especially on slopes or windy sites.Filling and Compaction
A well-graded fill material is placed carefully over the geogrid to avoid displacement. The fill should be compacted in layers to achieve the required density and ensure effective interlock between the soil and the grid structure.Quality Checks During Installation
Regular inspections are carried out to verify alignment, overlap, and tension. Any damage during installation should be repaired immediately to avoid performance issues.
Following these best practices ensures maximum soil interlock, improved load distribution, and long-term stability of the structure.
