Woven Geotextiles
Woven geotextiles perform the functions of separation and reinforcement. They are referred to by tensile strength and offer a very high load capacity. While woven fabrics are relatively impermeable and won't provide good drainage, their high compressive strength makes them an ideal choice for roads, parking lots, etc.
Non-woven Geotextiles
Non-woven geotextiles are felt-like and don't offer much in the way of compressive, tensile, or shear strength. But that's ok because their main functions are separation, filtration, and drainage. They are referred to by weight and ideal for any hardscape project where filtration or drainage is needed. Non-woven geotextiles can also be used for erosion control.
Polyspun Geotextiles
Polyspun geotextiles are non-woven fabrics and their main function is separation. While they are permeable and provide drainage, they will not provide any reinforcement to a project. Polyspun geotextiles are referred to by lifespan and are most commonly used as weed barriers.
Spunbond Geotextiles
In the world of fabric manufacturing, the spunbond process is considered the fastest manufacturing method for nonwoven fabrics. During the process, extruded filaments are spun onto a belt and bonded by applying heated rolls. Like polyspun geotextiles, spunbond fabrics will provide drainage but no reinforcement. They are referred to by weight and commonly used as weed barriers or as drainage fabrics.

Geotextile Material
● Jute: This is a versatile vegetable fiber that is highly biodegradable and can perfectly mix with the soil and provide nutrients for the vegetation.
● Coir: Also known as a Coir mat is a type of natural fiber made from the natural fiber that taken from the exterior husk of coconuts.
● Polyamide (PA): Polyamide is further categorized into two – Nylon 6 and Nylon 6.6 however, they are rarely used in geotextiles. The first polyamide (Nylon 6) is an aliphatic polyamide made from the polymerization of petroleum derivative known as caprolactam. The second type of polyamide is made from the polymerization of the salt of adipic acid as well as hexamethylene diamine.
● Polyesters (PSF): Are synthesized by polymerization of ethylene glycol with either terephthalic acid or dimethyl terephthalate acid. The resulting product has much more strength modulus, skulk resistance as well as general chemical inertness, thus making it a perfect fit for geotextiles. This geotextile material possesses very high resistance to UV radiation.
● Polyethylene (PE): Can be manufactured in a crystalline form, which is an essential trait in any fiber-forming polymer. The three main types of polyethylene are low density (LDPE), linear low density (LLDPE), and a the very common high density (HDPE). HDPE can also be found in a number of Root Barriers or Bamboo Barriers.
● Polypropylene (PP): A crystalline thermoplastic made by polymerization of propylene monomers.

Geotextile Laying Process Requirements
●Grassroots inspection: Check whether the grassroots is smooth and firm, and if there are foreign objects, they should be handled properly.
●Trial laying: According to the site conditions, determine the size of the geotextile, and try laying after cutting. The cutting size should be accurate.
●Check whether the width of the sala is appropriate, and the overlapping joints should be flat and moderately tight.
●Positioning: Use a hot air gun to bond the overlapping parts of the two geotextiles, and the distance between the bonding points should be appropriate.
●When suturing the overlapping parts, the suture line should be straight and the stitches should be uniform.
●After sewing, check whether the geotextile is laid flat and whether there are defects.
●If there is a phenomenon that does not meet the requirements, it should be repaired in time.
