5. Drill or break out a 6" diameter hole through the subfloor. Use of a rotary hammer drill and chisel or
core drill on concrete subfloors is recommended. If using a wet core drill, all water must be immediately
removed to avoid floor damage. See Figure 1.
6.
Route an accurate recess on the wood floor that allows flush and clean installation of the Floor Plate
(B). MAKE SURE TO FOLLOW THE INSTALLATION INSTRUCTIONS PROVIDED WITH
THE FLOOR PLATE . This recess will be approximately 3/8" deep. Take caution in this step to avoid
a sloppy, oversized or over depth recess. Optional Bison VB23IK installation templates will help in this
process. See Figure 1.
7.
Follow the instructions provided with the Floor Plate (B) and Floor Socket (C) to assemble the Floor
Plate (B) to the Floor Socket (C).
8.
Install duct tape over the top of the Floor Socket (C) to avoid grout entering the Floor Socket (C) during
installation.
9. Set
the Floor Socket (C) and Floor Plate (B) assembly into the prepared hole to insure that both the
Floor Socket (C) and the Floor Plate (B) fit neatly. Rework openings if necessary.
10. With
the Floor Socket (C) assembly properly sitting in the hole, inspect the installation area from the
lower level or crawl space.
11. Install
VB230 Concrete Form (A) to the underside of the floor with the grout retainer centered on the
Floor Socket (C) assembly. Make sure to use the proper sized anchors or attachment hardware.
See Figure 1.
12.
Fill the hole and VB230 Concrete Form (A) with premixed, non-shrink grout to within approximately 4"
of the playing surface. Using a pole, vibrate the grout to allow settling.
13.
Install socket assembly into the grout filled retainer. You will need to work the assembly into the hole to
allow the grout to surround the Floor Socket (C). If grout does not flow to the top of the hole in the
original sub-floor remove assembly and add more grout.
14.
Carefully follow the instructions included with Floor Plate (B) to attach Floor Plate (B) to the floating
wood floor to eliminate Floor Socket (C) floating when the grout is curing.
15.
After grout is set remove all hardware connecting the Floor Plate (B) to the wood floor and Floor
Socket (C). Re-install Floor Plate (B) to the wood floor with hardware provided. This allows the Floor
Plate (B) to move independent of the Floor Socket (C) when humidity changes in the gym.
Caution:
Do not allow use of floor sockets for 10 days as permanent structural damage to the socket installation
may occur when using regular grout. If using a quick set product, follow instructions provided with
that product
