Advanced materials and technologies play a decisive role in the current construction and engineering solutions where durability and cost effectiveness are top priorities. They are capable of securing durability, stability and cost effectiveness. Woven polyester geotextile is one of such materials that is actively used in embankment reinforcement, soil strengthening and geotechnical engineering. This article considers the current approaches to embankment reinforcement assisted by woven polyester geotextile, its benefits and applications.

Benefits of woven polyester geotextiles in embankment reinforcement
Main parameters
Woven polyester geotextile is made of strong polyester fibers and possesses a number of unique properties:
- High tensile strength;
- Resistance to aggressive agents and UV rays;
- Low deformation under load;
- Durability (service life is 50 years and more);
- Environmental safety.
These properties make woven polyester geotextile an ideal material for embankment reinforcement, particularly under poor soils and high loads conditions.
The current approaches to embankment reinforcement
Embankment reinforcement assisted by woven polyester geotextile has become an intrinsic part of the current construction technologies. Let’s consider key approaches and techniques used today:
- Multilayer reinforcement
Today’s projects often envisage the use of several geotextile layers that allows a uniform load distribution and prevention of embankment deformation. Multilayer reinforcement is particularly viable for high embankments and installations with enhanced requirements to stability. - Combination with other geosynthetics
Woven polyester geotextiles are often used in combination with geogrids, geomembranes and other materials. This approach allows to reinforce the structure, improve drainage properties and increase the overall stability of the embankment. - Application under complicated soil conditions
Modern technologies allow the use of woven polyester geotextile to reinforce embankments on poor, swampy and erosible soils. The material enables the base stabilization and prevents the soil migration. - Automated laying
Automated systems of geotextile laying are used more and more these days as they allow saving installation time and doing the work in a more accurate way. This is particularly important for large infrastructural projects such as construction of roads, bridges and railroad embankments. - Ecofriendly solutions
With attention to environment growing, woven polyester geotextile becomes a preferred material thanks to its durability and a recycling potential. The current approaches also include geotextile use in damaged landscape restoration and slope reinforcement.
The benefits of woven polyester geotextile in embankment reinforcement
- Higher bearing capacity of embankments;
- Lower risk of deformation and failure;
- Longer structure service life;
- Construction and service cost cutting;
- Applicability in a wide range of conditions.
Conclusions
Woven polyester geotextile is represented by Geospan PET in Gexa’s Geospan range. It has proven its effectiveness having been utilized in over 50 federal projects and 70 regional projects across Russia. The wide use of Geospan PET is a clear example of how the advanced geosynthetics contribute, thanks to their high performance, to increase in reliability and safety of infrastructural projects, as well as optimization of the cost of construction and operation.
