pports long-term performance across infrastructure applications. Modern construction projects often suffer from weak subgrade soils, inefficient drainage, and accelerated erosion. Without proper separation and filtration layers, these issues lead to higher maintenance costs and shortened service life. High-performance non woven materials, such as those used in geotextile products help engineers improve foundation reliability while reducing material usage. What problems occur when soil layers are not properly separated? When fine soils migrate into aggregate layers, load-bearing capacity decreases rapidly. This contamination results in rutting, settlement, and premature pavement failure, especially in road construction and access routes. Why is drainage a critical issue in geotechnical engineering? Excess water trapped within soil layers increases pore pressure and weakens structural integrity. Effective drainage layers are essential to prevent erosion and...
