It is common knowledge that reducing the water content of soil leads to a significant improvement in its compressibility and shear strength. Consolidation is a popular technique for lowering the soil’s water content in order to improve soft soil. To increase the bearing capacity of the soil and shear strength of the soil a ground improvement technique using prefabricated vertical drains is used. Prefabricated Vertical Drains (PVDs) are geosynthetic materials designed to accelerate the consolidation of soft, compressible soils by facilitating the drainage of excess pore water. They consist of a plastic core wrapped in a filter fabric, allowing water to flow vertically through the soil layers, which reduces settlement time and increases soil stability. PVDs are commonly used in construction projects like embankments, roadways, and land reclamation to strengthen weak soils. In the current research, four vertical drains are adopted: sawdust, sawdust wrapped with geosynthetic, sand drain, and jute wrapped with polyamide polyester geosynthetic (JPPG) to strengthen Kaolin soil. The stiffness of the drains is tested by two methods: (a) by applying uniaxial compression test using triaxial setup without any lateral pressure and (b) by applying all-round stress σ3 which is equivalent to lateral in situ soil using triaxial setup subjected to various consolidation pressures. The peak compressive strength observed for JPPG drain is best as compared to all other drains and also the loss of stiffness in JPPG is less compared to other drain materials thus showcasing good performance of JPPG drain as PVD for soft kaolin soil.
