Pondasi Kisocon Raya provided services of soil investigation with 200m exploratory drilling, the deepest ever in the history of geotechnical investigation in Indonesia for building foundation design. The investigation employed the special sampling tools enabling of retrieving high quality undisturbed soil samples from all kinds of soil formations encountered in the investigation and thus providing seamless information throughout the exploratory depths. High pressures and sophisticated laboratory soil tests conducted in Kiso-Jiban laboratories in Singapore and Tokyo, Japan, enable to obtain strength and consolidation characteristics of soil samples taken from great depths.
