7.1.3.1 New Pad to Exisng 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 152mm (6inches) minimum of compacted fill plus
the minimum required concrete thickness. Also excavate 51mm (2inches) 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 64mm (2-1/2inches) deep into the existing floor on
305mm (12inches) 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 102-254mm (4-10inches).
Concrete must be done in one pour so that the entire pad cures as one piece.
