What are Polyester Geogrids?
These are special Geosynthetic reinforcement material made primarily from polyester fibers. The polyester fibers are designed forming patterns suitable for civil and construction engineering projects.
For an improved performance, the polyester Geogrid may feature protective polymer coating. The coating ensures material resist chemical, UV or other environmental conditions that may compromise 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.
- Suitable for many construction applications, hence suitable for most construction projects.
Applications of Polyester Geogrid
Soil Reinforcement – Polyester Geogrid are widely used in reinforcement of soil structures to enhance its stability, load bearing capacity and preventing soil erosion. The types of soil reinforcement structure include slopes, retaining walls and embankments.
Airports Runways and Railways – They are used in airports runways and railway lines construction to provide more load bearing capacity and reduce settlement so that they have longer life of service.
Road Construction – Polyester Geogrids are commonly known to be used for road construction projects. During road construction, they are placed in within the road base to prevent cracking and differential settlement.
Soft Ground Stabilization – Soft ground can be made stable by use of polyester Geogrid material to distribute the load over a big area to reduce settlement.
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.
