Volleyball Floor Sleeves

General installation basics:

Find the center of the court in both directions; lay out sleeve locations very carefully.
There is not much room for error. Mark top plate location for reference.

If you are installing on a concrete slab, tile, or synthetic floor, you may remove the
concrete using a core drill and appropriate core bit for the sleeve. Be sure to allow
enough space to insert top flange of the sleeve without encroaching upon the top plate
area. If a core drill is not available, or if the installation is through an existing wood
floor, a series of small holes (1/2”-3/4”) will have to be drilled and the core chiseled out.
This is tedious work, but necessary. Water cannot be used in close proximity to the
finished floor, if even a small amount of water becomes trapped, it will cause the wood to
swell. Protect the finished floor especially carefully during this phase, Masonite works
well for this.

After removing the concrete, some excavation will need to be done to remove the fill
material below the slab, except in second story installations. Remove enough material to
accommodate the sleeve, plus a few inches. This amount will vary, depending upon the
floor type. Create a “mushroom” under the slab to ensure sufficient anchoring surface.
Some specialized digging tools can be created to simplify this process.

If a second story installation is being done, try to determine where the sleeves will be in
the ceiling below before starting installation. Make as certain as possible that obstructions
such as pipe, conduit, etc. are not going to be damaged. After removal of concrete, a
second story bucket will usually need to be used to provide anchoring. Install this
apparatus at this time. Seal any voids between the bottom of the slab and the bucket,
foam insulation or similar materials will serve this purpose.

Prepare the top floor surface to receive the cover plate. For synthetic floors, trace around
the top plate with a washable pen or pencil, carefully cut out synthetic material. Make
sure to use a very sharp blade, go slowly to ensure an accurate cut. This is going to be an
exposed, finished product.

For wood flooring, a router is necessary to remove the proper depth and width to receive
the top plate. Once again, mark the top plate location. Different template guides are
available, a template is preferred, free- hand routing is discouraged. Depth is critical, too
deep allows no wood to attach to. Too shallow creates a hazard. After routing floor to
proper depth and width, fit assembled sleeve and top plate unit into the hole. Make
certain the fit is perfect before proceeding with pouring the hydraulic cement. Mark and
drill holes to receive the screws for the outer ring of the top plate assembly. Set these
anchors. Make certain that the top flange of the sleeve has not been bent in shipment;
straighten it if necessary, this will affect the ability to level the sleeve.
