Abstract

A drainage assembly is disclosed for draining water from the vicinity of a subterranean construction surface, such as a subgrade foundation wall. The assembly comprises a hollow drainage panel formed by a sheet-like base and a filter media, the filter media being spaced apart from the base by a plurality of members that project from the inner surface of the base. The base has at least one hinge, and preferably two closely spaced parallel hinges, extending along its entire length between adjacent side edges, thereby allowing the panel to be easily folded and set into place against a foundation, with the portion above the hinge resting against the vertical foundation wall and the portion below the hinge resting atop the foundtion's horizontal footing. The apparatus further comprises a connector assembly that connects the panel to a standard drain pipe to convey water away from the foundation.
