Polyester geocomposite is a new geomaterial which takes the polyester fiber as the reinforcement material and combines short fiber or long fiber nonwoven. sale email: taylor@qdtanru.com sale mobile:(86)15595126252

The main body of this material is composed of two parts:

High-strength 400KN polyester geogrid (framework layer)

This is made by weaving high-strength polyester industrial yarns in a directional manner, with an ultimate tensile strength of up to 400kN/m, extremely low elongation rate, and excellent creep resistance. It can function like an "engineering framework", providing extremely strong reinforcement and interlocking effects for the soil, serving as the core support for the material's mechanical properties.

100KN black woven geotextile (functional layer)

The composite woven geotextile also has a tensile strength of 100kN/m, firmly combined with the grid, forming an integrated structure of "grid + fabric", and possessing functions of filtration, drainage, isolation, and protection.

Core advantages and mechanism of action

This composite structure enables the material to simultaneously possess the reinforcement capacity of a grid and the multi-functional properties of geotextile, perfectly adapting to scenarios of soft soil improvement:

1.Reinforcement and enhancement, increasing the bearing capacity of the foundation

The high-strength grid, through the locking effect, significantly improves the shear strength of the soft soil, evenly disperses the load stress, effectively reduces uneven settlement of the roadbed, and solves the problem of insufficient bearing capacity of the soft soil.

2.Isolation and filtration, preventing soil mixture

The geotextile can isolate the soft soil from the upper fill materials, preventing fine soil from being lost and coarse materials from sinking, while allowing water to freely drain, achieving a reverse filtration effect of "only allowing water to pass through, not soil", avoiding the erosion and damage of the soft soil.

3.Drainage and water discharge, accelerating soft soil consolidation

The water-permeable structure of the geotextile can quickly discharge the water in the roadbed, reduce pore water pressure, accelerate soft soil consolidation, and significantly shorten the stability cycle of the roadbed.

4.Corrosion resistance and aging resistance, long service life

The polyester material itself has excellent resistance to acid and alkali, and corrosion, and can work stably in complex underground environments, meeting the long-life requirements of major projects.

Engineering application scenarios

With its outstanding performance, it is widely adopted in various major infrastructure projects:

1.Roads / Railways- Soft soil subgrade treatment: Especially for sections of high-grade roads and high-speed railways with soft soil, it can significantly enhance the stability of the subgrade, reduce post-construction settlement, and extend the lifespan of the roads.

2.Water conservancy dams / River banks protection: Used for reinforcement and strengthening of dams and riverbanks, improving the stability of the structures and preventing risks such as pipe seepage and landslides.

3.Ports / Airports / Sea reclamation projects: Soft soil foundation reinforcement and drainage treatment, enhancing the bearing capacity of the site, meeting the requirements of heavy-load equipment and long-term operation.

4.Road embankment slopes and retaining walls: Reinforcement and strengthening of slope soil with reinforcement, improving the stability of the slope, reducing the earth pressure on the retaining wall, and lowering the project cost.
