Dead spots are locations on a sports floor where the ball rebound is significantly less than on the majority of the rest of the surface. Many maple flooring systems exhibit vibrations and sound variations when a basketball is bounced at different locations. Often, areas where vibrations and sound variations are observed are mistakenly termed “dead spots.” Provided the ball rebounds to a reasonably consistent height in comparison to other locations on the floor, areas where vibrations and sound variations are present do not typically qualify as true “dead spots.”
Concerns about “dead spots” are most often expressed with floating subfloor configurations. Floating floors often exhibit sound and vibration variations due to the structure of the subfloor components. Ball rebound can be affected on all subfloor configurations due to seasonal changes in flooring moisture contents and resulting system expansion/contraction. It is not uncommon for a true “dead spot” to move or disappear as a flooring system adjusts to varying seasonal moisture conditions — regardless of the subfloor system installed in the facility.
Most milling companies can provide laboratory-generated composite ball rebound figures for their flooring systems, and are available upon request for a fee to field test floors where “dead spots” are a concern
