grout into voids. When pressure injection is used, install dial indi-
cators on the baseplate or soleplate deck to confirm that epoxy
placement is being accomplished without lifting the baseplate or
soleplate deck.

12. The leveling shims or wedges used to level the baseplate or sole-
plate can be left in place after grouting. If for some reason they are
removed after the grout has cured, the resulting voids should be
filled with epoxy grout without aggregate.

If leveling screws are used, they should be removed after the grout
has cured to allow the full equipment weight to be distributed
evenly over the grouted area.

The foundation anchor bolts can now be retightened and the pump
and driver installed. The pump and driver are now ready for align-
ment.

Cement-Based Grout

1. The grout manufacturer’s requirements and instructions should be
strictly followed.

2. For dry packing of cement-based grout, refer to Wume 3, Chap-
ter 3 of this series.
3. Grout forms should be built of materials of adequate strength and
should be securely anchored and shored to withstand the pressure
of grout under working conditions. Forms should be tight against
all surfaces, and joints be sealed with tape.

Grout forms must be coated with form oil on areas that will come
in contact with the grout to keep them from becoming bonded to
the grout. All oil should be removed from the concrete, baseplate,
or soleplate before grouting. To permit easy cleanup, cover all
surfaces where grout may splash.
4. Prior to placing the grout, the top surface of the concrete founda-
tion should be saturated with water for the time period recom-
mended by the grout manufacturer. Excess surface water and wa-
ter in the foundation bolt holes should be removed just prior to
placing the grout.
