Abstract
The specification discloses foam insulation board for use in plaza deck construction, the upper and lower surfaces of which contain drainage channels. To avoid problems of easy breakage, especially of the kind associated with larger foam insulation boards having upper and lower drainage channels, the present invention discloses orienting the lower surface drainage channels 90.degree. with respect to the upper surface drainage channels, such that the two opposing surfaces of channels are perpendicular to each other.

Insulation panel, for use in constructing horizontal parking structures, plaza decks, and the like, comprising:
- a panel of foam material having first and second sets of generally parallel drainage channels located in opposing top and bottom surfaces of said panel, respectively, said first set channels on said top surface being oriented generally perpendicular to said second set drainage channels on said bottom surface, said panel being free of generally parallel top and bottom channels, whereby points of narrow cross section between top and bottom channels are isolated in a checkerboard fashion rather than running the full length or full width of said panel.
A method for constructing a plaza deck/parking structure comprising:
- providing a plurality of panels of foam plastic insulation having first and second sets of generally parallel drainage chapels located in opposing top and bottom surfaces of said panel, respectively, said first set chapels on said top surface being oriented generally perpendicular to said second set drainage chapels on said bottom surface, said panel being free of generally parallel top and bottom chapels, whereby points of narrow cross section between top and bottom channels are isolated in a checkerboard fashion, rather than running the full length of full width of said panel;
- providing a base deck:
- placing a waterproof membrane on top of said base deck;
- placing said plurality of foam plastic panels on top of said waterproof membrane, and installing a concrete wear layer over said panels.
