Leveling and Grouting
The unit should be level in all directions. Wet the con-
crete pad according to the grout manufacturer’s direc-
tions. Mix a sufcient amount of grout. The grout must
be an expanding grout rather than shrinking to provide
a tighter bond. Follow the manufacturer’s recommenda-
tions for setting, precautions, mixing, and grout place-
ment, nishing and curing. The grout must be worked
under all areas of the feet with no bubbles or voids. If the
grout is settled with a slight outside slope, oil and water
can run off of the base. Once the grout has cured, torque
the anchor bolts as per HILTI instructions.
