Polyester Geogrid

Polyester geogrid is a kind of geosynthetic material. It is made of high-strength polyester yarns. These yarns are knitted or woven into a grid-like structure that are coated with a protective polymer coating. And polyester geogrid’s strength can be very high, with design values of up to possible 1000 kN/m. The strength of a geogrid allows positive reinforcement of embankments, steep slopes, retaining walls and other vertical soil structures. Geogrids interlock with the soil providing long term reinforcement and are the most cost-effective method of creating additional horizontal space. Polyester geogrids have excellent long term creep performance. 

Benefits of Polyester Geogrid

– High tensile high tensile strength making the Geogrids suitable for soil reinforcement applications.
– Suitable in applications where there is exposure to chemicals due to its ability to resist them.
– Increases overall stability of the structure and reduces the risk of differential settlement by distributing applied loads evenly on the surface.
– Compatible with varieties of soil types such us sand, clay, silt and others types of soil.
– Available in different sizes and specifications to be applied effectively on various projects requirements.
– A lightweight Geogrid for easy installation and handling.

Types of Polyester Geogrid

There exist many varieties of Geogrid made from polyester material. The variation depend on many classification factors are such as:

Wrap Knitting Polyester Geogrid

They are unique for their high tensile strength yarns which are carefully interlocked for optimal performance. Usually, they form grid like structure through a process known as warp knitting.

Bi-directional Woven Polyester Geogrid Fabric

It is a type of polyester fabric material having equal strength in both transverse and longitudinal direction. This help it to distribute tensile forces in the two direction enhancing load bearing capacity.

Polyester Uniaxial Geogrid

Type of polyester material consisting of high strength polyester fibers arranged in a rectangular grid aperture shape. This is a type of polyester geogrid that is designed to provide reinforcement in only one direction.

Biaxial Woven Geogrid from Polyester

Polyester Geogrid that is constructed by intersecting fibers to form two dimensional grid like structure to provide strength and reinforcement in two perpendicular directions.

• Road Construction:
• Subgrade Reinforcement: Polyester geogrid is used to enhance the stability of road subgrades, evenly distribute loads, reduce deformation, and prolong the lifespan of roads.
• Asphalt Pavement Reinforcement: Polyester geogrid can improve the structural integrity of asphalt layers, minimizing cracking and rutting
• Retaining Walls: Polyester geogrid helps to reinforce the soil in retaining walls, enabling them to withstand lateral earth pressure and providing long-term stability.
• Slope Stabilization: Polyester geogrid is used to prevent erosion and landslides on slopes and embankments, enhancing overall safety in hilly or sloped areas.
• Embankment Construction: Polyester geogrid reinforces embankments to enable them to bear heavy loads without deformation.
• Landfills: Polyester geogrid is used to separate waste materials from the surrounding environment in landfill construction and enhance the stability of waste containment structures.
• Railways: Polyester geogrid is employed to reinforce the track bed, ensuring it can withstand the heavy loads of trains and maintain its integrity over time.
