Soil stability is a crucial element and a crucial factor in the construction and civil engineering world. This is because soil is the key to a project’s long-term success. Geotextile bidim are one innovation widely used to improve soil stability. This material is a non-woven synthetic fabric specifically designed for civil engineering applications, including highways, embankments, railways, drainage systems, and slope protection.
Function Bidim Geotextiles for Separation, Filtration, Drainage and Protection
Bidim is a continuous filament nonwoven needlepunched geotextile produced using a combination of recycled PET and virgin plastic materials. Its unique three-dimensional structure ensures high elongation, excellent biaxial strength, and effective permeability, allowing water to flow freely while preventing soil particles from migrating. These characteristics make Bidim suitable for varied engineering roles, including filtration, separation, drainage, and protection systems.
Geotextiles bidim have four main functions, separating different soil layers, acting as a filter to prevent fine particles from entering the drainage system, acting as a drainage medium, and acting as protection against mechanical damage to geomembranes or other underground structures. The advantages of this material include its high durability, good permeability, and adaptability to field conditions.
By using geotextiles bidim, engineers will experience significant benefits, including increased efficiency, reduced maintenance costs, and extended structural life. Therefore, it’s no surprise that these geotextiles are a smart choice for a variety of projects. This article will delve deeper into how they perform each function and their advantages over other similar materials.
Separation
This geotextile prevents the mixing of subgrade and other aggregate materials, making it highly useful for maintaining the foundation stability of roads, railways, or other soft soils. Its robust structure can reduce aggregate use by up to 50%, helping to reduce costs and environmental impact.
Filtration
As water flows, this geotextile acts as a static filter, allowing water to pass through but retaining fine soil particles. This prevents clogging of the drainage system, thus maintaining optimal performance over the long term.
Drainage
This geotextile acts as a pathway for lateral or vertical water movement. It can drain excess water from the subgrade and support subsurface drainage systems. Furthermore, this geotextile can reduce pore water pressure on slopes or retaining walls.
Geotextiles provide effective mechanical protection to geomembranes or soil structures from damage, including penetration by rough objects or pressure, especially when applied to landfills, ponds, or dams.
Advantages of Bidim Geotextiles
Bidim geotextile offer several advantages that make them an ideal choice for construction projects. One advantage is their high mechanical strength. This is because the material is made from recycled or virgin resin. This allows them to withstand tensile stresses and heavy loads on projects under construction.
Furthermore, their installation time is relatively quick compared to other conventional filters. This significantly reduces the volume of excavation. Geotextiles are more cost-efficient because they reduce the need for aggregates in construction projects and reduce the size of drainage channels.
This also reduces the frequency of maintenance. Importantly, geotextiles are environmentally friendly, as some of their products are derived from recycled materials, thus supporting sustainability efforts.
As a flexible and multipurpose material, geotextile bidim can enhance the performance and durability of various infrastructure projects. Through their functions of separation, filtration, drainage, and protection, geotextiles are an efficient and economical solution for addressing soil problems. Using these geotextiles can extend the lifespan of structures and reduce long-term maintenance costs. Therefore, selecting the right geotextile, such as Bidim, is a strategic step to ensure the success of a project.
