2.3.2 WASHER INSTALLATION ON NEW FLOOR:
2.3.3 NEW PAD TIED TO EXISTING FLOOR:
If the existing floor is not reinforced concrete that meets the minimum
thickness requirements, DO NOT install a pad on top of the existing floor.
The existing floor and the machine pad must be tied together as one
piece as follows:
1) Cut an opening through the existing floor that is wider and deeper
than the washer as shown below. See Machine Mounting Details for
dimensions.
2) Excavate to a depth that allows for 6" [152] minimum of
compacted fill plus the minimum required concrete thickness. Also
excavate 2" [51] under the existing floor so that the new concrete is
poured under the floor as well.
3) Back fill with clean fill dirt and compact dirt, making sure to allow
for the minimum thickness concrete pad to be poured.
4) Drill holes around the perimeter of the existing floor to install
reinforcing bars to tie the new pad to the existing floor. Drill 2-1/2"
[64] deep into the existing floor on 12" [305] centers around the entire
perimeter.
5) Clean holes and fill half-way with acrylic adhesive rated for
commercial-grade machine installations.
6) Use #4 (60 ksi) reinforcing bar to tie the new pad to the existing
floor. Tie the bars together at intersections and use supports to hold
bars in the proper depth in the pad.
7) After adhesive has cured, pour 4000 psi concrete up to level with
the existing floor plus any extra elevated pedestal desired 4-10" [102-
254].
Concrete must be done in one pour so that the entire pad cures as one
piece.
