A mount device is disclosed for securing a swimming starting block to a floor. In at least one embodiment, the mount device provides an upper mount conduit engagable with the starting block and sized for at least partially extending into a receiver conduit in the floor. A lower mount conduit is positioned below the upper mount conduit and has an outer diameter or width sized for being completely positioned within the receiver conduit. An expansion bolt extends through respective substantially coaxially aligned bores of each of the upper mount conduit and the lower mount conduit, each of the bores having a diameter that is relatively larger than a diameter the bolt. Upon tightening the expansion bolt, the lower mount conduit is urged along an angled common axis toward the upper mount conduit, such that opposing long outside surfaces of the upper mount conduit and lower mount conduit are urged in opposite, substantially horizontal directions, creating a frictional engagement within the receiver conduit.

A diving board having a shell including a top surface with one or more pockets formed thereon. The pockets are recessed inwardly from the top surface of the shell and sized to receive a non-slip tread surface therein. The tread surface may be made from any of a variety of suitable materials, such as a composite material primarily comprising cork, and arranged such that the tread surface is substantially flush relative to the top surface of the shell when seated therein. An adhesive layer may be used to adhere the tread surface in the pocket of the shell.
