Warp Knitted Polyester Geogrid

 

Polyester Geogrid is a type of geosynthetic material made from polyester fibers. It is commonly used in civil engineering projects for soil stabilization and reinforcement. Knitted polyester geogrid refers to a specific manufacturing process where the polyester fibers are knitted together to form a grid-like structure, providing enhanced strength and durability.

 

 
Types of Polyester Geogrid
 

Polyester Biaxial Geogrid

It is a high-performance soil reinforcement product primarily used for slope stabilization and retaining wall installations. Constructed of high molecular weight and high tenacity polyester yarns utilizing a complex knitting process and polymeric coating to provide superior engineering properties, Polyester Biaxial Geogrid is engineered to be mechanically and chemically durable, in both the harsh construction installation phase and in aggressive soil environments.

Polyester Uniaxial Geogrid

It is a geogrid constructed of high tenacity polyester yarns and coated with PVC. Uniaxial grid is best used in retaining wall and reinforced slope construction because it is strongest in the machine direction.

Polyester Geogrid Composite with Nonwoven Geotextile by Glue

It is the composite of poloyester geogrid and needlepunched nonwoven geotextile or spunbond nonwoven fabric.It is characterized by good heat resistance. It is widely used in asphalt pavement reinforcement.

Polyester Geogrid Stitched with Nonwoven Geotextile Impregnated By Bitumen

It is an Asphalt Reinforcement Composite that polyester geogrid with light weight Spunbond Nonwoven Fabric or Needlepunched Nonwoven Geotextile.

Features of Polyester Geogrid

  • High tensile and long-term strength
  • High tear strength
  • high modulus polyester geogrid
  • Excellent creep resistance
  • Flexible and durable
  • Increased pull-out resistance and compound strength
  • Optimum stability of the junction of the grid
  • High chemical and biological resistance
  • UV resistance / Cost effective
  • High resistance to installation damage and ease of installation
Advantages of Polyester Geogrid

Polyester geogrid, a specialized type of geogrid, offers several advantages in road construction:

High Tensile Strength

Polyester biaxial geogrids have excellent tensile strength in both the longitudinal and transverse directions, making them ideal for distributing loads evenly.

01

Durability

These geogrids are resistant to chemical and biological degradation, ensuring a longer lifespan for road construction projects.

02

Easy Installation

Polyester biaxial geogrids are lightweight and easy to handle, reducing installation time and labor costs.

03

Cost-Effective

By extending the life of roads and reducing maintenance costs, these geogrids provide a cost-effective solution in the long run.

04

Environmentally Friendly

They are environmentally friendly, as they reduce the need for extensive excavation and replacement of road materials.

FAQ

 

Q: What is polyester geogrid?

A: Uniaxial polyester geogrids are engineered materials made from high-quality polyester fibers. These geogrids are designed to offer superior tensile strength in one direction, making them ideal for applications that require reinforcement and stabilization along a single axis.

Q: What are the disadvantages of polyester fibre?

A: The cons of polyester are mostly environmental, such as high energy and water consumption, pollution, and inability to biodegrade. But there are material cons as well, such as a higher likelihood of pilling, running, and pulling.

Q: What are the properties of polyester geogrid?

A: Polyester Geogrid is resistant to soil erosion, and it can be used for retaining walls, agricultural landscapes, and more. Polyester Geogrid has many advantages over traditional materials, including: It is resistant to moisture and fungus. It is lightweight and easy to transport.

Q: What direction is “Uniaxial” geogrid installed in a reinforced wall application?

A: The roll width direction needs to be installed with the “Machine Direction” perpendicular with the wall length. The machine direction is the direction you would face if you were pulling on the roll to unroll it. Uniaxial geogrids have their principle strength along this machine direction. The grid elements in the XMD (cross machine direction) are used only to support elements in the MD. The geogrid panels in each layer (lift), usually do not have to be overlapped, but commonly are 4”-6”.

Q: What is the relevant geogrid property engineers need in designing retaining walls?

A: Long Term Design Strength or Long Term Allowable Strength is the property needed to specify geogrid into reinforced walls. This is derived from taking the Ultimate strength and dividing it by 4 main factors of safety > Installation Damage, Creep, Chemical & Biological Degradation. Many other factors come into play but this is relationship of Ultimate Strength to Long Term Design Strength in a nutshell.

Q: What are the two main types of materials used in making Uniaxial Geogrids (retaining walls)?

A: The types are divided into flexible (polyester) grids or rigid (polypropylene) grids. Almost all vendors use flexible (polyester) in their grids mainly because of its higher resistance to creep. Creep is the elongating of the grid under constant tension. If the creep rate doesn’t flatten out, the wall may eventually fail. Polypropylene grids appear to be “stiffer” initially but with polypropylene’s higher creep rate, polyester type grids in the long term will be effectively stiffer. Because of this creep factor, polyester geogrids are superior to polypropylene geogrids. In addition, polyester geogrids are generally lower in cost, easier to apply (more flexible) and come in wider rolls.

Q: What are the requirements for a geogrid?

A: The geogrid must be resistant to damage during construction, including ultraviolet degradation, and it must have long-term resistance to chemical and biological degradation caused by the materials being reinforced.

Q: What is PET geogrid?

A: PET geogrid is a high strength coated geogrid manufactured from high tenacity polyester (PET) yarns, knitted to form a structured grid. It is used to reinforce soils where extremely high tensile strength with low elongation is required.

Q: Which way do you lay a geogrid?

A: To install the geogrid, simply roll it out and allow it to follow the natural contours of the ground. Generally, the direction of laying and vertical spacing of multiple layers will be specified in the design documents.Geogrid can be placed on the subgrade, either parallel to a road centerline or at right angles.

Q: Why do you need geogrid?

A: Geogrids provide reinforcement, stabilization, and even filtration when used with properly sized aggregate fills. Made from polymers such as polypropylene, polyethylene, or polyester, they are used widely in civil engineering applications.
