Woven geotextiles are more durable than non-woven geotextiles. However, if you are plagued by large amounts of standing water, nonwoven geotextiles are an excellent solution. It's also worth noting that in addition to being the perfect drainage solution, nonwoven geotextiles offer excellent strength and durability, so they can still be used for roads, airports, retaining walls, landfills, mining, and many other applications.

What is Geotextile?
Geotextile, also known as geotextile, is a permeable geosynthetic material made of synthetic fibers that are needle-punched or woven. Geotextile is one of the new geosynthetics. The finished product is textile-like, generally 1-8 meters in width and 50-100 meters in length. Geotextile is divided into woven geotextile and non-woven geotextile.

What is non-woven geotextile?
The specification of non-woven geotextile is selected between 100g/m2-1000g/m2, which is composed of oriented or random fibers, the main raw material is polyester staple fibers or polypropylene staple fibers, and is made by needle-punching method, and its main use is the berms of rivers, sea rivers and lake embankments, poldering, wharves and locks flood control and rescue works, etc. It is an effective way to keep soil and water and to prevent tube surges. Nonwoven fabrics are moisture-proof, breathable, flexible, lightweight, non-flammable, easy to decompose, non-toxic and non-irritating, colorful, inexpensive and recyclable. For example, it adopts polypropylene (pp material) granule as raw material, and is produced by high-temperature melting, silk spraying, net spreading, hot pressing and winding in a continuous one-step process.

What is woven geotextile?
Woven geotextile is a series of geosynthetic materials formed to meet the various characteristics and requirements of geotechnical engineering. Filament woven geotextile is made of high strength and high modulus polyester filament, polyamide, polypropylene and other industrial filament woven, with good physical and mechanical properties, oxidation resistance, chemical stability, tensile strength of up to 2000Kn/m, width of 5.2 meters. Woven geotextile is used in geotechnical projects such as rivers, coasts, harbors, highways, railroads, docks, tunnels, bridges and so on, which can meet a variety of uses.

Woven geotextile makes use of the advantages of industrialization and the advantages of low cost of synthetic fiber; it has the characteristics of high strength, low elongation, good durability, corrosion resistance, etc.; woven geotextile has the characteristics of structural stability, high rate of conformity of engineering parameters to meet the requirements of all kinds of geotechnical engineering, and it can be used for different purposes such as anti-filtering, isolation, reinforcing, protection, etc., and it is a class of products of relatively high value in geotechnical engineering.

What is the difference between woven geotextile and non-woven geotextile?
According to the different production process, geotextile can be divided into woven geotextile and non-woven geotextile two kinds of geotextile, these two kinds of geotextile in some aspects have certain differences:

1. Differences in production process

Non-woven geotextile, also known as non-woven geotextile, is made of filament and staple fibers interwoven with the help of mechanical equipment, through the needle punching and other production processes; it is produced by at least two groups of yarns interwoven with each other.

2. Performance differences

Due to the differences in production processes, the impact on product performance is not the same, although the non-woven geotextile has a good deformation effect, but its deformation effect is not as good as the woven geotextile, woven geotextile in the horizontal direction has a comparable tensile strength effect in the reinforcing effect is more practical characteristics.
