ABSTRACT:
Apparatus for delivering grouting material, in controlled quantities and at desired pressures, to selected zones along the vertical extent of a borehole which includes the provision of vertically spaced retractable and expansible barriers or dams adapted to isolate a portion (zone) of the borehole wall from portions (zones) above and below it while grouting material is forced into the ambient earth in the region of said zone, with minimal possibility of escape to other zones. In the preferred method of utilizing the apparatus, the first zone to be grouted is the lowest, the grout controlling barriers or dams being moved upward step-by-step or continuously to higher zones while the rate and/or pressure of the grout delivery are controlled to effect distribution of the grout as desired.
