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.

Lime should be supplied in water resistant paper bags or in bulk. The ground surface and adjacent structures will be monitored at all times during grout injection for surface movement heave.
Grout Delivery System. Drilling reports will contain at least the following information: Name of driller, type of drill, method used, date, location of hole, tip depth or elevation of injection pipe.
Subsurface Soil Stabilization Guidelines for Limited Mobility Displacement Grouting in Florida . typical pumping distance from the truck to the injection point, and at the discretion of.
This paper focuses on the use of limited mobility grouts (similar to stiff. pumps to the injection pipes can be flexible high-pressure hoses or steel pipes.
Cement containing lumps should be rejected or screened to remove lumps. There should be a reliable mechanical means of measuring the quantity of grout pumped in every stage to within 0.
Compaction Grouting Services and Equipment Judy Company
Equipment Drilling equipment is normally required for the installation of grout injection pipes. The compaction grouting process will progress in stages within each injection pipe using the bottom up method.
Typically an initial injection grid is completed, followed by a secondary grid with injection points in between the initial grid points.
