mixer” driven by a variable-speed drill.

is entrained in each bag of aggregate, which causes air bubbles in the
cured grout. Fold the aggregate into the epoxy until the aggregate is com-
pletely wet. Add all the bags of aggregate and mix until completely wet.
Consider using the containers in which the epoxy resin was mixed for
placement of grout. Slowly pour the grout into the baseplate grout holes
to allow air to escape. Pour from the center of the baseplate and allow the
grout to flow to the outside edges, displacing the air through the vent
holes (Figure 3-42). Do not use vibrators or rodding to place epoxy
grout. Continue to fill the baseplate until the grout runs out the vent holes
on the wooden-top form at the baseplate flanges (Figure 3-37). Cover the
