Geogrids are geosynthetic materials used for reinforcement and stabilizing soil structures. They have high tensile strength and a higher elastic modulus than soil, allowing them to distribute loads more effectively and provide better reinforcement in construction applications than they otherwise would. Geogrids can be used in soil reinforcement, reinforcement of retaining walls, slope stabilization, etc. Geogrids are formed by intersecting surface grids of elements extending in two directions, one in the direction of the machine and the other vertically, forming the shape of the apertures. These apertures vary depending on application and manufacturer’s specifications.
Geogrids are made of different polymer materials such as polyester, polyvinyl alcohol, polyethylene, or polypropylene. At Strata Geosystems, we manufacture PET geogrids.
The successful reinforcement of geogrids depends on three properties of geogrids: physical, mechanical, and environmental. Physical properties, like tensile strength, elongation and flexural rigidity, influence the initial interaction with the soil. Mechanical properties, which include creep resistance, junction strength, and interface friction, govern the long-term performance of geogrids under stress exuded by the soil. Lastly, chemical and environmental properties address the geogrid’s resistance to biological and chemical degradation from surrounding elements.
The physical properties of geogrids determine their characteristics that define their behavior and performance. These properties include:
The mechanical properties of geogrids determine their characteristics that define how geogrids respond to external forces and loads. These properties include:
Geogrids offer versatile solutions for many geotechnical engineering applications, by raising the stability and performance of the structures:
Stabilization of road bases and foundations: In the construction of pavements and roads, geogrids contribute to enhancing subgrade conditions, reinforcing base courses, sub-bases, and surface layers. They mitigate the problem of lateral displacement of railway ballast, minimizing track settlement caused by weak soils. When dealing with clayey subgrade soils in pavements, geogrid reinforcement raises the pressure needed to penetrate the composite soil foundation. Rigid geogrids exhibit superior performance in soft subgrade conditions compared to flexible alternatives, thanks to their quicker reaction to applied loads.
Erosion control: Geogrids efficiently combat soil erosion using a dual strategy. Initially, they strengthen the soil matrix by redistributing stresses, boosting its load-bearing capacity. This increased resilience reduces the soil’s vulnerability to erosion caused by wind, rain, and external forces. Additionally, the geogrid acts as a physical barrier, absorbing the kinetic energy of erosive elements such as rain and wind.
Strata Geosystems geogrids offer innovative solutions tailored to various applications in geotechnical engineering, providing cutting-edge solutions to the above mentioned applications. These geogrids are meticulously designed to enhance essential properties, ensuring excellence and durability in soil stabilization, erosion control, highway infrastructure, roadway improvements, reinforced steep slopes, retaining walls, energy projects, landfill construction, and more.
StrataGrid™, a high-performance uniaxial geogrid utilized in soil reinforcement solutions, is created by weaving high-tenacity polyester yarn into a stable network of apertures to form a geometric grid. Its exceptional tensile strength and high molecular weight provide reinforcement for both vertical and horizontal structures, while its trademarked UV-stabilized coating ensures durability against environmental factors –be it installation related strains or soil conditions. StrataGrid offers leading elongation and stress-strain values, guaranteeing a structure lifespan exceeding 100 years. With widths up to 5.7 m, a wide range of ultimate tensile strengths up to 800 kN/m, and adherence to international guidelines like Ministry of Road Transport and Highways (MoRTH), Indian Roads Congress (IRC), and American Association of State Highway and Transportation Officials (AASHTO), StrataGrid™ is certified and tested by the Indian Institute of Technology (IIT) for quality assurance.
The StrataGrid™ Biaxial geogrid is a groundbreaking innovation in pavement construction that revolutionizes the durability and longevity of flexible pavements, particularly in highway embankments. These biaxial geogrids, engineered with the highest quality materials, offer exceptional tensile resistance at lower elongations, surpassing conventional solutions in the market. With a strength ranging from 20kN/m to 150kN/m and a width of 5m, SGB grids provide superior reinforcement for pavement base layers, resulting in reduced maintenance costs and extended pavement life. One of the key advantages of the SGB Grid Series is its ability to reduce pavement crust thickness, leading to a faster and more efficient construction process.
Our specialized line, StrataGrid™ HyTen, comprises geogrids with unparalleled strength, boasting tensile strengths exceeding 200 kN/m (13,704 lbs/ft). These geogrids are primarily used in the construction of embankments over soft soil grounds, including organic peat and clay-type soils. By employing safe design methods, StrataGrid™ HyTen allows for direct construction on challenging soil types. It effectively limits vertical settlements and provides a solid reinforced soil foundation over voids, ensuring stability and longevity.
