Preparation of Materials and Execution of Ground Improvement Works for Sio Market Store Project

Preparation of materials and execution of ground improvement works for the Sio Market Store project, including 12,000 linear meters of single-fluid Jet Grouting columns with a diameter of 100 cm, drilling depths ranging from 2 to 14.5 meters, and an unconfined compressive strength of 3 MPa.

The project involved the execution of Jet Grouting columns, soil improvement beneath the foundation, and enhancement of bearing capacity in artificial fill soils. Major challenges included unstable soil conditions, the use of pre-drilling techniques, and grout loss due to high soil permeability.
