It is a fabric made from non-woven polyester fibers and is manufactured in several weights starting from 150 g/m2 to 1000 g/m2. It is used to separate or isolate two dissimilar materials, such as two layers of soil with different properties, as it works to keep the soil components from moving and mixing with each other. , thus preventing subsidence in different soil layers, so it is used in all types of civil and structural engineering. It is manufactured according to Egyptian standard specifications for manufacturing insulation materials.
When there are two different layers of soil, there must be a separating layer between them that allows water to pass only so that there is no subsidence in the soil, such as placing a layer of sand on a layer of gravel. Over time, sand will subside between the gravel if there is no insulating layer between them, and this layer is Non-woven geotex material, the main function of this product is filtration and separation, and it is also used for strengthening and protection purposes.
