When roads and railways are built, embankments are formed, it is very important to protect and strengthen their foundation, especially if construction is carried out on soft soils. Geotextiles, which can be woven and non-woven, perfectly cope with this task.
The raw material for woven geotextiles is polypropylene in the form of fibers and ribbons, for non-woven geotextiles (dornite) polyester fibers are also used. Woven geotextile is a fabric obtained by weaving ribbons and fibers from polypropylene. It can also include solid-woven loops for fasteners, such canvases can be used under water and have a longer service life. The tensile strength when applied in the longitudinal direction for different versions of woven geotextiles varies widely, in the range from 15 to 1200 kN / m. This is one of the factors that determines the price set for geotextiles. It also depends on the size, thickness, density of the material and feedstock.
In addition to these objective factors, a lot depends on who you buy geotextiles from, the longer the chain between the final consumer and the manufacturer, the higher the share of mark-ups and transportation costs in the cost of the material. Therefore, it makes sense to purchase a woven geotextile and mandrel from the company SibStroy-Ecology, a manufacturer of waterproofing and other materials. Geotextiles having a strength above 60 kN / m can be subjected not only to static, but also to significant mobile loads, since its deformation modulus is very high. To facilitate the installation process, woven geotextiles can be sewn into larger panels of the required size.
Important advantages of this material are chemical passivity, which allows its use in alkaline soils, and resistance to ultraviolet radiation. In addition to the function of reinforcing, hardening the bases, woven geotextile performs a separation function. It also serves as a filter, the combination of three functions in one material makes it unique and profitable. With low elongation, geotextiles have high strength, for each specific object you can choose the version of optimal strength due to a wide range. The material can be used underground and under water, it is characterized by exceptional moisture resistance, which leads to its use for shore strengthening, in the construction of breakwaters. It is also used in temporary armored structures.
