Geotextile needle-punched: types, technical characteristics, application

Geotextile needle-punched is a unique material, combining a relatively low cost at the same time with distinctive technical properties. It has a greater scope of use, compared to other types of this material, due to the fact that it is economically more profitable for many projects. Non-woven base is made by needle-punched technique from polymer monofilaments, which are divided into two types: polyester and polyamide.

Kinds

Of the variants of geosynthetic materials, non-woven and woven variants are most often encountered. The latter have a high degree of elasticity, sufficient strength and homogeneous structure, while they do not differ in good water permeability. This material is suitable for protective purposes, layer separation and reinforcement.

Non-woven geotextile is a product made of filaments or fibers, which are joined together by a chaotic interlacing, depending on the method of hardening.

Calendered material is created by the method of connecting continuous filaments under the influence of high temperatures. Such a manufacturing option reduces the likelihood of discontinuities during operation, increases the waterproof and strength characteristics. Such products are characterized by a homogeneous structure with a large elongation and a high degree of elasticity.

Useful Features

Geotextile needle-punched, in addition to the properties that provide convenient use, has a list of obvious advantages:

• The drainage characteristics of the material are much superior to other types produced by the thermosetting method.
• Durability and reliability. Similar species have much smaller properties, since the constituent organics are subject to negative external factors and can be destroyed in a few years.
• Geotextile needle-punched absolutely does not absorb moisture, which can not boast an organic version.
• Availability of bandwidth. Such a material passes water in several directions at the same time, so it copes with its considerable volumes.
• Compliance during processing.
• Does not attract rodents.
• Distinctive resistance to destructive external influences (microorganisms, temperature differences, ultraviolet radiation, dampness).
• Easy and convenient installation.

What is used for?

For a better understanding of the possibilities, it is worth considering for two purposes at the same time: in terms of use and main application.

Its application needle-punched found in the following:

• Drainage for high-quality removal of excess moisture from structures of different types.
• Separation of soil adjacent layers. An example is the separation of sand from the fertile layer in order to avoid mixing and subsequent washing out.
• Prevention of the destruction of materials to increase the duration of quality performance.
• Filtration of liquid and simultaneous separation of solid small particles.
• Strengthen the soil to prevent landslides in areas prone to them.

Applications

The main areas of use include the following:

• Creation of tunnel passages;
• Laying of highways and railways;
• Implementation of works related to landscape design;
• Piping of any purpose;
• The qualitative consolidation of artificial protective embankments and slopes;
• Creation of landfills for utilization;
• Arrangement of hydraulic engineering facilities (canals, artificial ponds);
• Installation of technical elements;
• Construction of houses.

The list mentioned above includes only the main part of the application areas, there are actually more of them.

Geotextile needle-punched: production

The creation of the foundation is the main stage. Through it are subsequently stretched fastening strong yarns, forming a durable fabric with a non-standard structure. The technological process is carried out on a specially developed needle-punching machine. He has jagged sharp needles, due to them this method also acquired such a name. The manufacturing process takes much material and time, thanks to this, a relatively low retail value is formed.

Characteristics

Geotextile needle-punched, price Which varies from 17 to 59 rubles per square meter, has many uses. Before choosing it is necessary to determine the purpose, and depending on this, select the material with the required characteristics, depending on the parameters. A competent selection will allow using it more efficiently, prolong the period of operation and reduce financial expenses.

The main parameter is the type of substrate used in production. The most common are polypropylene and polyamide. They have similar characteristics of strength, durability and reliability. The latter are guaranteed by the absence of organic materials, characterized by rapid damage.

The tear force reflects the degree of load transfer without loss of consumer characteristics and functional properties. Non-woven geotextile with maximum strength is used in fixing the slopes of roads and embankments.

The density with respect to this material shows its thickness, as well as the amount of polymer contained. As this parameter increases, reliability and quality increase.

The parameters of the relative elongation are given in percentages. There is a wide range of values. But it is not always rational to use a material with a significant elongation, for example, in works that prevent soil displacement. Also, the transverse and longitudinal values may differ, this should also be taken into account when laying.

The pore diameter in micrometers is expressed. This property is of particular importance in the implementation of drainage projects, while taking into account the type of soil and the moisture content in it.

The filtering parameters reflect the throughput of the material. Most often needle-punched fabric is characterized by High ratio.

Non-standard use

Geotextile needle-punched "Tehnonikol" recently found its application in gardening. It is worth noting that, due to the extensive field of use, it becomes an appropriate option for protecting plantations both in summer and in winter. It is able to protect from scorching sunlight, preventing excessive evaporation of moisture, as well as from negative temperatures. The material does not become an obstacle to air exchange, it is not saturated with water, due to which it does not freeze and retains its original characteristics.

In the role of the mulching synthetic base, the needle-punched geotextile 300 gm2 is also used. An additional reason for its acquisition is the fact that it prevents the further growth of weeds, and when creating an additional fertile soil layer, the material will act as a separation layer that prevents mixing.

Rational use in terms of a long period of operation. Also, in the case when the root system of trees begins to grow in all directions and destroy the integrity of the soil, it is possible to limit the undesirable growth in the planning of the site. For this, a material is placed deep into the soil, which prevents horizontal growth.

Geotextile heat-treated has gained popularity among landscape designers. With the help of it, it is possible to create various paths, flower beds of non-standard form, decorative elements.

Conclusion

This material is relatively budgetary with extensive functionality, it has acquired a wide distribution and has technical unique properties. As a rule, such a geotextile perfectly copes with its purpose, showing its universality and undeniable advantages over other materials.
