Geotextile retaining wall as a construction material is very beneficial for the soil. You may often see the banks of rivers, lakes or walls beside toll roads. The banks of lakes or rivers are usually not eroded by water and the highways remain safe from landslides. This is because there is a retaining wall. A retaining wall is a construction with a special design to be able to withstand the movement of the soil due to the force of lateral soil or water pressure.
However, currently retaining walls are not only used as a construction of public spaces. There are also those who use it for the exterior of private homes. The goal is to be able to maximize the function of the wall as the main protector of the house.
Get to Know the Geotextile Retaining Wall
Geotextile retaining wall is a building structure used to hold soil or other materials using geotextile material. Geotextile is a synthetic material that has high filtration, separator and tensile strength properties. This geotextile has a synthetic material made from polymer fibers, such as polypropylene or polyester.
Material specifically designed for use in geotechnical applications. This geotextile is used extensively in civil construction to strengthen slopes, protect roads or buildings from soil erosion. It will even maintain vertical walls.
Geotextile Retaining Wall Function
Retaining walls are generally used to control soil movement and maintain steep slopes or ground surfaces. However, in the case of a geotextile retaining wall, the geotextile is used as the main retaining element. Geotextiles are usually placed between layers of soil to reduce soil movement and erosion.
Retaining walls can be used in a variety of situations, including slope containment, river bank protection and erosion control. In addition, for the purposes of soil compaction, and other construction projects. The main advantage of using geotextiles is the ability to reduce hydrostatic pressure in the soil.
In this geotextile is placed in several layers. Coarser coating on front to reduce erosion. While a smoother layer on the back to facilitate water drainage. These structures are often strengthened by the use of additional materials, such as stone or concrete to provide greater stability.
Types of Geotextile Retaining Wall
This gravity retaining wall is a type that depends on its own weight to withstand lateral soil pressure. This structure is designed with sufficient weight to balance the pressure of the ground behind it. Gravity retaining walls are made of blocks of concrete or natural stone which are arranged tightly and supported by a layer of geotextile placed between the blocks.
There is also a type of reinforced soil retaining wall that uses a combination of geotextile and retaining material such as geogrid or geocell. Geotextile is used to separate the original soil from the retaining material. While geogrid or geocell provides additional strength to the soil to withstand lateral pressure.
Gabion retaining walls are a type that uses boxes in the form of metal nets filled with natural stone or other materials. Geotextile is used to encase and separate the stones in the gabion box, thereby preventing erosion and movement of the material.
Mechanically Stabilized Earth (MSE) A type of geotextile wall that uses fillers such as soil, gravel or crushed stone. Additionally, it is reinforced with mechanically bonded geogrids or geotextiles. Then there is the sheet pile wall using metal panels called sheet piles that are pressed into the ground to form a retaining wall.
By using a geotextile retaining wall, the structure can provide an economical and effective solution. In particular to hold soil, reduce erosion, and maintain steep slopes.
