Thermobonded geotextile is made from a continuous filament based on polypropylene and polyester, which is bonded into webs under high temperature. If we compare this material with needle-punched, it is non-woven and has a smaller thickness, but its density is quite high and varies from 70 to 110 g/m2. You may have heard of this material if you are an avid gardener. This product is generally very common in many areas of human activity, so it is known everywhere.
Thermobonded geotextile also has excellent water resistance, while its resistance to deformation is extremely high, even comparable to that of woven fabrics. This fabric is similar to needle-punched and has a significant elongation at break, which makes it resistant to high loads.
Description
Use of thermally bonded fabriccontributes to savings in construction work, while their quality is not reduced. Reinforcement allows you to make the roadbed more reliable. This increases its wear resistance and durability. If you use geotextiles, you can significantly reduce the amount of base materials, but the quality of the fabric will not be lost.
Repair of the road, which was arranged using such geotextiles, is required less frequently than the highway, which was laid using the old technology. In landscaping, this material provides excellent levels of drainage performance and is an excellent choice for green roofs.
Main varieties and their characteristics
The material described above is represented by several varieties that differ in the level of surface density. For example, a material marked TC 70 differs in the above parameter within 70 g/m2. Breaking load is 4.9 kN/m, breaking lateral load remains the same.
On sale you can find thermally bonded geotextiles marked TC 90. The numbers in the designation indicate the surface density. But the breaking longitudinal and transverse loads are 6.5 kN/m. You can purchase geotextiles with a higher surface density, in this case we are talking about the TC 110 material. It is a product with a breaking longitudinal and transverse load, which are equal to 70 kN / m.
Use area
Thermo-bonded geotextile has an excellent ability to pass moisture and retain soil, therefore it is used by builders when laying roads and arranging critical facilities.
This material is actively used by landscape design specialists, in addition, it can be found in the following areas:
- in construction;
- when forming a green roof;
- when arranging venues;
- in the process of protecting the foundation;
- when creating obstacles in the way of root systems;
- when strengthening the walls of drainage channels;
- if necessary, protect insulation and waterproofing membranes from mechanical stress.
Non-woven thermally bonded geotextile is used in the construction of roads, as well as children's and sports grounds. With it, you can protect the base of a building for any purpose from the roots of trees. On the way of growth of rhizomes, geotextiles can become a reliable barrier, which helps in the arrangement of flower beds, flower beds and alpine slides.
Main Functions
The above material can perform the following functions:
- separation of layers of the roadway;
- soil reinforcement;
- drainage organization;
- soil filtration;
- protect soil from erosion.
Geotextile can be used for reinforcing non-metallic materials. With it, they sharelayers of the roadway, and also protect the soil from displacement. Geotextiles can form the basis of a drainage system, protecting watercourses from debris, sand and other fine particles.
Geotextile from TechnoNIKOL
Thermally bonded geotextile "TechnoNIKOL" is a polymeric fabric, which consists of fibers arranged in a chaotic manner. They are connected mechanically when exposed to temperature. Fabrics are produced with a surface density of 100 g/m2. The most impressive density reaches 700 g/m2 per square meter.
The material exhibits neutrality to aggressive environments, is environmentally friendly, non-toxic and resistant to the effects of the sun, bacteria, microorganisms, alkalis, acids and temperature extremes. During the operation of thermally bonded geotextile, the price of which is 30.8 rubles. per square meter, no degradation by-products are produced.
This geotextile has excellent physical and mechanical properties, among them it should be noted:
- resistance to mechanical damage;
- high modulus of elasticity;
- universal filter capacity.
The material is widely used in civil, industrial and road construction, as well as in the oil and gas industry, landscaping and domestic use.
Use area of geotextile 150 g/m2
Thermo-bonded geotextile 150 is a material with an appropriatedensity. It is used in construction work, but there are other areas of application. It can be seen when constructing slopes, in which case the material is combined with a geogrid. They are also used in the manufacture of geocomposites. This geotextile is great for everyday tasks, such as sheltering plant seeds. It is even used in the manufacture of medical wipes.
Conclusion
Geotextile appeared relatively recently, but during its existence managed to gain popularity among consumers. This is due to the wide scope of use of this material. It is used not only in industry and construction, but also for solving problems in everyday life. In support of the latter fact, it can be argued that summer residents are well aware of what geotextiles are. They use it in their beds when they need to keep weeds out and prevent soil from moving.
