In this paper a new micropiling method and its verification study are presented. The proposed method is distinguished to conventional micropiles in that woven geotextile is used to increase frictional resistance. In order to increase frictional resistance, woven geotextile is wrapped to the reinforcement and pressurized grout is injected inside of the geotextile. Grout is mainly injected in two steps: (1) gravity-type grouting inside drilling steel-casing and (2) pressurized grouting into the geotextile pack after inserting reinforcement and removing the drilling steel-casing. The second step builds a very tight interface between surrounding ground and pile-structure and provides higher frictional resistance. Field installation was performed for verifying constructability of micropiles with the new method. The field study indicates that the new method is capable of providing a better quality of micropile construction.
