Pilling Grade Bentonite Powder
We are offering a wide range of Pilling Grade Bentonite Powder. At the time of boring for Pile, the sides of the bore hole are subjected to numerous external forces and pressure like active earth pressure, hydrostatic pressure, pore pressure, etc due to underground water. As a result the side of the bore become unstable and may collapse if the soil layers remain weak. Due to its thixotropic property, bentonite is used as a supporting fluid to counter the external pressures and stabilize the sides of the bore hole.
