Polyester filament geotextiles (often referred to as geotextiles) are technical fabrics widely used in construction and geotechnical engineering. Here are the main advantages and applications:

Advantages of polyester filament geotextiles 

Polyester filaments provide very high strength with low elongation, making them ideal for applications with high loads. 

Unlike polypropylene or polyethylene, polyester fabrics show only minimal deformation under sustained load. 

Resistant to many chemical substances in the soil, especially acids and bases found in natural soils. 

Polyester is hydrophobic and rot-proof, ensuring a long service life in the ground. 

With appropriate treatment, geotextiles are also temporarily resistant to UV radiation. 2–4 weeks of UV tolerance is usually sufficient for the construction phase until covering. 

Roll material is easy to cut and install, even in large projects.

Typical applications

For stabilizing slopes, embankments, and road subgrades, especially in soft or low-bearing soils. 

Between different soil layers to prevent mixing and increase load-bearing capacity. 

Under gravel or paving layers to distribute loads and prevent settlement. 

For retaining walls, noise barriers, and other geotechnical structures. 

When combined with nonwoven fabrics, it can also drain water and provide filtration functions.
