Warp Knitting Polyester geogrid fabric is fabricated by the complex knitting process using high tenacity, high oriented polyester filament to provide superior engineering and long term design strength properties.  BPM warp knitting geogrid is specifically designed for improved tensile reinforcement capacity in two principle directions. Our warp knitting polyester geogrid is engineered to be mechanically and chemically stable and biologically unaffected by soil micro-organisms. It is used for both harsh construction installation phase and in soil reinforcement application where strength develops uni-axially which can provide further chemical, mechanical and ultraviolet protection. 

The railway embankment is a structure that takes and transmits the orbital gravity and the dynamic action of the train. It is the basis of the track and is an important building that guarantees the operation of the train. The embankment is a kind of earth and stone structure and it is located in various landforms, geology, hydrology and climatic environments. It sometimes suffers from various disasters such as floods, mudslides, collapses and earthquakes. In order to reinforce the railway subgrade, Geogrid fabric is widely used in the construction of road and railway roadbeds and has achieved very good results.

The commonly used geogrid fabric for reinforcing railway subgrade are biaxially-stretched plastic geogrid and polyester geogrid. These two materials have high tensile strength, high temperature resistance, corrosion resistance, light weight, easy construction, resistance to aging, and cement, soil and broken materials. Warp knitting polyester geogrid fabric is suitable for reinforcement of various embankments and roadbeds, protection of slopes, reinforcement of cave walls, reinforcement of foundations for large airports, parking lots, dock yards, etc., which can be used in railways, highways, and roads.

1 Appplications of Warp Knitting Polyester geogrid fabric for Aircraft runways 

  • Reinforcement of iron roadbeds. Geogrid fabric  is used to reinforce the railway subgrade. Composite materials and road surface materials are integrated together to effectively distribute loads, prevent the loss of road slag and deformation of the roadbed, improve the stability of subgrade and withstand greater variable loads.
  • Railway track slag protection. Due to train vibration and wind and rain, the road slag is lost. It is wrapped with geosynthetics to prevent the loss of ballast and improve the stability of roadbed.
  • Railroad Retaining Walls. Geogrid fabric are used to reinforce the retaining walls on the side of the railway. For example, the platform and the cargo platform in the railway station can extend the service life and reduce maintenance costs.
  • Railway slope protection. Geogrid fabric is used for slope protection on both sides of the railway to prevent stones and fine soil from sliding down, then increase the service life of the railway and reduce maintenance costs.

2 Why Chose Warp Knitting Polyester Geogrid Fabric for Railway Project

In 2017, an inspection team from China Railway Corporation visited our company to assess our GSJ100-100 biaxial warp knitting polyester geogrid fabric, which is specifically designed for reinforcing railway projects. During their visit, the inspection team thoroughly examined our production capacity and the quality of our geogrid fabric.

To ensure the reliability and performance of our geogrid products, the inspection team conducted rigorous tests using precision testing instruments. They also conducted a comprehensive comparison with several other suppliers in the market. After careful evaluation, our company was selected as the qualified supplier for the railway project.

Following the selection process, we promptly signed a sales contract with the China Railway Corporation to facilitate the delivery of the geogrid fabric to the construction site within a two-week timeframe. This commitment ensured that the project could proceed as scheduled and that our high-quality geogrid fabric would be utilized for reinforcement treatment in the railway construction.

By choosing our GSJ100-100 biaxial warp knitting polyester geogrid fabric, the China Railway Corporation demonstrated their confidence in our company’s production capability and the superior quality of our geogrid products. This selection validates our commitment to providing reliable and efficient solutions for railway projects.

In summary, the decision to choose our warp knitting polyester geogrid fabric for the railway project was made after a thorough inspection and evaluation by the China Railway Corporation. We were selected as the qualified supplier based on our production capacity and the high-quality performance of our geogrid fabric. This partnership highlights our dedication to delivering exceptional products and meeting the stringent requirements of railway construction projects.
