Geotextile, which is a technology that is especially used at the substructures and its functionality remaining in the forefront, is used in many fields. This material, which is an indispensable product of civil engineering, protects the ground and prevents the collapse of the base part and ensures the longevity of the structure.
Geotextile which is the intermediate material of soil mechanics strengthens the reinforcement to the ground; separation, filtration, and drainage. Geotextiles are produced in various weights and sizes.
By measuring the floor of the area to be covered, the order process must be made accordingly. Geotextile production may vary according to the technique. It can be produced in two different classes as braided and non-braided.
In addition to the shape they are also available in different models. What are these models? There are three different types of shapes: flecked geotextile felt, polyester geotextile felt and polypropylene geotextile mat. How about looking at the geotextile varieties together?
Geotextile Types Based on the Shape
Nonwoven Geotextile; It can be described as a non-woven textile type whose raw material is polypropylene and polyester, where needling and fibers are combined.
After the geotextile mat has started to function at the place where it is laid; It is a permeable textile product that can be easily used with any floor material in relation to slip, soil and geotextile engineering.
Nonwoven geotextiles having a homogeneous structure are made from synthetic or natural cuts and fibers of desired length which are added to each other by their own methods without being converted into yarn.
Braided Geotextile; Braided geotextile is a kind of high strength and durable geotextile, it can be used anywhere, it contains continuous yarn on both sides.
In order to take advantage of all the technical properties of the yarn, high strength is obtained even at low elongations. The yarns are woven at right angles to each other. The yarns may weaken due to friction and continuous use, but since the knitted geotextile yarns are strong, they are resistant to such situations.
Technical characteristics of yarn; quality, high strength and safe. Such knitted geotextiles are produced especially on classic or modern looms. They are woven in a knee width and a knee lengthwise.
What Are the Raw Materials Used in Geotextiles?
The production method of each company may be different from each other. The structural properties of the product can be changed with different contents. The content of a generally made geotextile; It consists of obtaining certain raw materials by adding certain ratios. A geo textile content; polypropylene, polyester, polyamide and polyethylene. Polypropylene is the most commonly added raw material and constitutes 63% of all raw materials.
What Are the Content Characteristics of the Raw Materials Used in Geotextiles?
Polyamide; The polyamide, which is sensitive and resistant to water, shows high resistance to abrasion. This product, which remains in water for a long time, decreases its mechanical properties after a certain period of time.
In order to increase the material properties to the desired level, additives are used. The purpose of the additives is to prevent the product from deteriorating due to heat and light.
Polyester; It is an easy sloped product and it has durability. It has the structure to maintain its properties up to 200 degrees. It is a kind of raw material which is resistant to friction and protects its structure.
It provides protection against different metals and chemicals in particular, but the product may still not be able to withstand some chemicals, it is necessary to test and get continuous data. You can safely use it against sea water, of course, the product must be tested and developed constantly.
Polypropylene Polyethylene; Highly resistant to all chemicals, this raw material is also very sensitive to friction. It is a substance with low density and resistant to steam. Polyethylene with high density is hard we structure.
When its density is high, its chemical resistance increases. With various additives this raw material can be brought to very good places. If this material receives too much light, is exposed to very hot temperatures and stops in extremely humid environments, the risk of deterioration is high. For this reason, it is very important to pay attention to the storage and use of this product.
In Which Areas Is Geotextile Used?
Geotextile mats are especially used in infrastructure works and in the intermediate parts of insulation layers. The reason for the use of these layers; It acts as a set against cracking and has carrier properties.
Geotextiles; separates the water and heat insulation from each other and prevents the excess water from clogging by wrapping into drainage pipes. It is a product especially used on the road grounds and the bases of railways.
Geomembrane, which is frequently used in football stadiums and carpet pitches, extends the life of the field and reduces the cost and error risk that may occur. The production and application of geotextiles is a highly specialized business. If you want to buy and apply geotextile, you should do a very serious research beforehand. The higher the quality of the product, the lower your investment cost.
