Geogrids are geosynthetics composed of a network of interconnected ribs with regularly spaced openings that facilitate bonding with the soil. They play a key role in reinforcement, enabling soil improvement, subgrade stabilization, asphalt resurfacing, and the construction of reinforced retaining structures. Depending on their structure, geogrids can be biaxial, multiaxial, or uniaxial, and are manufactured from polyethylene, polypropylene, polyester, or a composite of fiberglass and elastomeric polymers.
They are also classified as extruded or woven, according to their manufacturing process. Extruded geogrids are high-strength geosynthetics made from polypropylene resins through extrusion, punching, and stretching processes (uniaxial, biaxial, or multiaxial). Its lattice design, with regular openings—square, rectangular or triangular—increases load-bearing capacity, reduces settlements and stabilizes the soil by transferring stresses through its interconnection and tensile strength.
Advantages
Optimization of road structures: Geogrids allow reduction of base layer thickness in roads and highways, significantly lowering quarry exploitation costs, construction times, and maintenance requirements.
Extended service life: Substantially increase the durability of roads, railways, and reinforced access routes.
Versatility in containment design: Facilitate the construction of structures with steeper angles of repose, optimizing space and stability.
High mechanical performance: High tensile stiffness and excellent soil– geogrid interaction (interlock), ensuring superior structural efficiency.
Superior durability: High environmental resistance to degradation factors such as moisture, temperature, and chemical agents.
Cost and material reduction: Reduce the need for traditional materials, generating economic savings and environmental benefits.
Ease of installation and sustainability: Fast, simple installation with reduced environmental impact.
Resistance to cyclic loads: Maintain performance under repetitive loading, ideal for high-traffic infrastructure.

Asphalt Layer Reinforcement – Puerto López–Puerto Gaitán Road, Colombia
The existing flexible pavement exhibited a moderate level of cracking that compromised its surface integrity and accelerated the structural deterioration of the constructed asphalt overlays.
As an intervention strategy, a reinforced asphalt overlay incorporating a fiberglass geogrid was applied. This solution was designed to control crack reflection and improve stress distribution, thereby enhancing the overall performance and durability of the pavement structure.
Road Rehabilitation: Santa Marta – Riohacha – Parahuachón Concession, Colombia
The flexible pavement presented an advanced state of deterioration, evidenced by deformations and cracking of medium to high severity. This condition compromised its structural functionality and posed a direct threat to the roadway’s durability throughout its service life.
In response, granular base reinforcement was implemented through the incorporation of T-6 multiaxial geogrids, with the objective of increasing bearing capacity and effectively controlling damage propagation.
This solution significantly improved pavement performance within the design period, optimizing structural behavior and reducing long-term maintenance costs.
Foundation Improvement – Hospital Lucio Aldazábal Pauca, Huancané, Puno, Peru
During the construction of the new Hospital Lucio Aldazábal Pauca, foundation soils with low bearing capacity were identified, insufficient to withstand the new structural load demands.
As a solution, foundation reinforcement was carried out through the incorporation of granular material combined with geosynthetics, using T-6 rigid multiaxial geogrids. This intervention increased soil shear strength and achieved the required bearing capacity, ensuring a solid and reliable foundation for the hospital facility.
Subgrade Improvement – Tampico International Airport, Tamaulipas, Mexico
In the subgrade improvement project at Tampico International Airport, Tamaulipas, Mexico, soft soils with low undrained shear strength were identified.
To address this geotechnical condition, a subgrade improvement system using geosynthetics was implemented, consisting of nonwoven geotextile combined with a T-7 multiaxial geogrid. This solution reinforced the ground structure, increased stiffness, and improved the performance of the airport infrastructure, ensuring a stable and reliable foundation.
