Geotextile - Geotextile
Geotextiles are fabrics used in combination with soil, that have the ability to separate and filter, stiffen and protect, or filter. Typically made of polypropylene or polyester, geotextile fabrics come in one of three basic forms:
woven.
Needle punched (it looks like hair).
thermal.
Composite geotextiles and products such as geogrids, geosynthetics, geonets, geogrids, and more -- can bring geotechnical and environmental benefits to engineering design.
All constructions of different types are built on the land or in the land, and the land is a big word that carries many meanings, and therefore the part of the land that bears the structure or close to it surrounding it is called “the soil”, when any person thinks of establishing any facility, the first thing he searches for is the soil On which this facility will be built, several questions come to mind: Can this soil bear the structure to be built on it with the size required for this facility? Is this soil suitable for the establishment of this structure on it? Is this soil suitable for the function of the structure required to be established on it or in it? Studying the soil is the first practical step towards establishing any engineering project.
And now, with the high price of land all over the world, the prevailing trend is to make maximum use of the soil and load it as much as possible, and this increases the importance of the soil before the implementation of the installations, hence the importance of strengthening the soil and arming it with geotextiles.
The importance of the geotextile material is due to the fact that it is an essential and important factor in strengthening the soil and arming it with geotextiles.
The first to create a method of building structures from reinforced soil is the French engineer VIDAL in 1963,
These structures generally consist of soil and reinforcing elements. The reinforcing elements are flexible materials that bear high tensile stresses.
These facilities are implemented by backfilling the used soil over the reinforcing elements in the form of horizontal layers, so that the reinforcing elements remain covered from below and above with layers of soil.
This method is used to construct structures such as: retaining walls, bridge piers, and the construction of semi-existing slopes, using only reinforcement elements and soil. Thus, a great safety factor can be achieved in these types of facilities.
General definition of geotextile:
The word geotextile consists of two parts: (geo), meaning earth, and (textile), meaning fabric.
