A support pad is provided having a lightweight core component defining an essentially open space between side walls thereof. An interlocking pattern, such as alternating recesses and extensions, are defined along the side walls of the core component. A hard formable shell material, such as concrete, generally surrounds the core component along the side walls and upper surface thereof. The shell material forms within the recesses along at least one of the side walls and non-movably sets the core component within the shell material. The interlocking pattern or recesses defined on the sides of the core component are configured so that any number or pattern of core components can be interconnected depending on the sides and configuration of the desired support pad.
