Needle-punched geotextile is a unique material that combines relatively low cost at the same time with distinctive technical properties. It has a greater scope than other types of this material due to the fact that it is more cost effective for many projects. The non-woven base is made by needle-punched technique from polymer monofilaments, which are divided into two varieties: polyester and polyamide.
Views
Of the options for geosynthetics, non-woven and woven options are most common. The latter have a high degree of elasticity, sufficient strength and a homogeneous structure, while they do not have good water permeability. This material is suitable for protective purposes, separation of layers and reinforcement.
Non-woven geotextile is a product made of threads or fibers, which are fastened together by a chaotic weave, depending on the method of strengthening.
Calendered material is created by joining continuous filaments under high temperatures. This manufacturing option reduces the likelihoodbreaks during operation, increases the waterproof and strength characteristics. Such products are characterized by a homogeneous structure with high elongation and a high degree of elasticity.
Useful Features
Needle-punched geotextile, in addition to the properties that provide convenient use, has a list of obvious advantages:
- The material's drainage performance is far superior to other types produced by thermal bonding.
- Durability and reliability. Similar species have much lower properties, since the organic matter included in the composition is exposed to negative external factors and can be destroyed in a few years.
- Needle-punched geotextile does not absorb moisture at all, which the organic version cannot boast of.
- Availability of bandwidth. Such material passes water in several directions at the same time, thanks to which it copes with its significant volumes.
- Compliance during machining work.
- Does not attract rodents.
- Distinctive resistance to damaging external influences (microorganisms, temperature changes, 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: by area of use and main application.
Needle-punched cloth found its application in the following:
- Drainage for high-quality removal of excess moisture from structures of various 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.
- Preventing material degradation to increase quality uptime.
- Filtration of liquid and simultaneous separation of solid small particles.
- Soil stabilization to prevent landslides in areas prone to them.
Application areas
Main uses include:
- creating tunnel passages;
- laying highways and railways;
- implementation of works related to landscape design;
- supplying pipes for any purpose;
- high-quality fixing of artificial protective embankments and slopes;
- creating landfills for recycling;
- development of hydraulic structures (canals, artificial ponds);
- installation of technical elements;
- construction of residential buildings.
The above list only includes the main part of the applications, there are actually many more.
Geotextile needle-punched: production
Building the foundation is the main step. Strengthening strong threads are subsequently pulled through it, forming a durable canvas with a non-standard structure. The technological process is carried outon a specially designed needle-punching machine. It has serrated sharp needles, due to which this method has acquired such a name. The manufacturing process takes a lot of material and time, thanks to this, a relatively low retail price is formed.
Features
Needle-punched geotextile, the price of which varies from 17 to 59 rubles per square meter, has many applications. Before choosing, it is worth deciding on the purpose, and depending on this, select a material with the required characteristics, depending on the parameters. Proper selection will allow you to use it more efficiently, extend the period of operation and reduce financial costs.
The main parameter is the type of base used in production. The most widespread are polypropylene and polyamide. They have similar characteristics of strength, durability and reliability. The latter are guaranteed by the absence of organic materials that spoil quickly.
The tensile strength reflects the degree of transferred loads without loss of consumer characteristics and functional properties. Non-woven geotextile with maximum strength is used in securing road slopes and embankments.
Density for a given material indicates its thickness as well as the amount of polymer it contains. As this parameter increases, reliability and quality increase.
The elongation parameters are indicated as a percentage. There is a wide spreadvalues. But it is not always rational to use a material with a significant elongation, for example, when working to prevent soil displacement. Also, the transverse and longitudinal values \u200b\u200bmay differ, this should also be taken into account when laying.
The pore diameter is expressed in micrometers. This property is of particular importance in drainage projects, and soil type and moisture content must be taken into account.
Filtration parameters reflect the throughput of the material. Most often, needle-punched fabric is characterized by a high coefficient.
Non-standard usage
Geotextile needle-punched "TechnoNIKOL" has recently found its application in horticulture. It is worth noting that, due to the extensive area of use, it becomes a suitable option for protecting plantings both in summer and in winter. It is able to protect from the scorching sun, preventing excessive evaporation of moisture, as well as from negative temperatures. The material does not become an obstacle to air exchange, is not saturated with water, due to which it does not freeze and retains its original characteristics.
In the role of a mulching synthetic base, needle-punched geotextile 300 g m2 is also used. An additional reason to purchase it is the fact that it prevents the further growth of weeds, and when creating an additional fertile layer of soil, the material will act as a separating layer that prevents mixing.
Rationalapplication in terms of long service life. 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 unwanted growth when planning the site. To do this, material is laid deep into the soil, which prevents horizontal growth.
Heat-treated geotextiles have gained popularity among landscape designers. With its help, it is possible to create various paths, flower beds of non-standard shape, decorative elements.
Conclusion
This material is relatively inexpensive with extensive functionality, it has become widespread and has technical unique properties. As a rule, such geotextiles do an excellent job of their purpose, showing their versatility and undeniable advantages over other materials.
