Jet Grouting ~ this is a means of consolidating ground by lowering
into preformed bore holes a monitor probe. The probe is rotated
and the sides of the bore hole are subjected to a jet of pressurised
water and air from a single outlet which enlarges and compacts
the bore hole sides. At the same time a cement grout is being
introduced under pressure to fill the void being created. The water
used by the probe and any combined earth is forced up to the
surface in the form of a sludge. If the monitor probe is not rotated
grouted panels can be formed. The spacing, depth and layout of
the bore holes is subject to specialist design.
