Geotextiles (geotextile): purpose, properties, application

What is geotextile?

Under the name "geotextile", a group of materials of various purposes, composition, production method and even type is hidden. Most often they are laid "on" or "in" the ground. The main component is synthetic threads or fibers. These materials are durable, relatively inexpensive. In some cases, fiberglass is used in production, sometimes natural materials are added to synthetics - cotton, wool. All this changes the properties and characteristics of the material, affects the area of use.

Raw materials for the manufacture of geotextiles

The most common are polyester and polypropylene geosynthetics. Polypropylene has a denser structure, usually higher tensile strength, not so hairy in appearance. The lack of polypropylene - it reacts poorly to ultraviolet - becomes fragile. Therefore, as a covering material, it is better not to use it.

Polypropylene geotextiles can have any color, as dyes can be added to the feedstock. The base is white, but more often the color changes due to additives that are added to obtain special properties. For example, in order for geosynthetics to better tolerate sunlight.

Polyester geotextiles can be made from recycled materials (plastic bottles, etc.), which is why it is usually cheaper. Polyester threads do not work long, so the material is more “shaggy” and less tensile. Color - any, but more often gray (Dornit brand), black, beige or brown, very rarely white. This is when it is made from primary raw materials.

To summarize, then polypropylene geotextiles should be used where high strength is needed - when arranging roads, paths, strengthening slopes, foundations, fillings. Polyester material - suitable for beds, flower beds, slides and other landscape tricks.

Application

Geotextiles have appeared recently, but are already used in various fields: in construction, landscape design, gardening and horticulture, with the construction of pedestrian walkways, highways and runways. Hygiene products, disposable medical clothing and underwear are made from the same material, only of low density, and used as rough upholstery for upholstered furniture. In general, the scope of geotextiles is very wide, and it is worth knowing which type is suitable for what purposes.
