Disclosed may be an intermediate surface for supporting a small paver, wherein the surface can also be used to exchange heat with the pavers. In one embodiment, the apparatus may be a hextray defined by a frame with a hexagonal lattice for supporting pavers. The hextray preferably features a tubing track throughout the lattice to accommodate heat exchange tubing. In operation the hextray may be positioned above a pedestal or directly on a subsurface. In embodiment, the hex tray may be outfitted with insulation and a metal plate so that heat may be exchanged with pedestals via fluid passing through tubing installed throughout the hexagonal lattice. In a preferred embodiment, the hextray features a slot in its corners for receiving a locking disk or locking slider.
