Grout Injection Volume Measurement System. Perform grouting program under the supervision of personnel experienced in grouting for settlement control. A level control system will be installed and operated by the Contractor for use during grouting. The column elements are often constructed overlapping to form large treated masses. Due to the high pressures involved, relatively large column elements can be constructed through small boreholes giving the technique a very good limited access advantage. Hole layout and spacing System used to monitor movement of surface or structures. Grout will either be supplied by transit mix or mixed on site. The adjacent primary grout pipes will be grouted prior to installing or injection into the secondary pipes.
