A subfloor drainage panel is provided for draining moisture from a floor. The subfloor drainage panel has an upper member, a lower member attached to the upper member, and an intermediate member located in the lower member. The lower member includes a plurality of first projections extending away from the upper member, a plurality of second projections extending toward the upper member, and at least one drain hole defined in the first projections. The first projections support the subfloor drainage panel on a surface. The intermediate member has a plurality of openings each configured to receive therethrough a portion of one of the second projections so as to contact and support the lower member. The lower member is configured to define a gap between a portion of the lower member and the surface, with the gap being configured to allow fluid to pass therethrough.
