Assessment of Jet Grout Column Diameter during Construction Using Electrical Resistivity Imaging
This paper presents the implementation of an electrical resistivity push probe to estimate the diameter of jet grout columns. The probe is pushed into the jet grout column immediately after mixing and removed such that no damage is done to the column. The probe allows direct coupling of electrodes to the soilcrete, providing a demonstrated improvement over existing techniques. Field testing was conducted on columns with diameters ranging from 0.9 m to 2.5 m at two sites, in Berlin, Germany, and Miami, Florida. The results show that the technique routinely estimates the diameter to be within 5% of the as-built diameter.
