A short casing stub of about.6 inches was left above the bottom of <br /> the excavation. Next, additional grout was pumped into the pit and brought up to a depth <br /> sufficient to cover the casing stub by about 6:inches. The remainder of each excavation <br /> was filled with clean material and the asphalt pavement was patched with concrete. <br /> Harlin Knoll, of the SJC-EHD, inspected this work. <br /> i <br /> irk <br /> • i <br /> 2937 Veneman Avenue,Suite B240 Geo-Phase:Environmental Inc.
