Abstract
A subterranean panel drain is provided comprising a unitary prefabricated panel having a serpentine shaped transverse cross-section defining a series of substantially vertically arrayed corrugations. A plurality of spaced slots is provided in each alternately arrayed corrugation with the slots preferably being disposed at an angle to a horizontal plane passing through the panel. In one preferred embodiment, the subterranean panel drain may be employed in abutting relation against a foundation wall to form a conduit between moisture in the soil adjacent the foundation and a conventional drain pipe at the base of the foundation. In another preferred embodiment, a pair of subterranean panel drains may be placed in back-to-back relation to form a curtain drain for transferring collected moisture in soil to a drainage pipe.

A subterranean panel drain comprising a unitary member having a top edge, a bottom edge, and first and second sides, said unitary member having a transverse cross-section defining a plurality of alternately disposed ridges and valleys on said first side and said second side respectively, the ridges on said first side corresponding to the valleys on said second side and the ridges on said second side corresponding to the valleys on said first side, said valleys defining a plurality of substantially vertically disposed fluid-flow channels extending between said top edge and said bottom edge, and a plurality of openings disposed in said ridges on said first side to communicate with the corresponding channels on said second side, said openings being inclined upwardly from said first side to said second side, said unitary member being adapted for subterranean installation whereby water in soil adjacent said first side is capable of flowing through said openings, entering said corresponding channels on said second side, and being directed along said corresponding channels toward said bottom edge of said member.
A self-draining structure comprising:
- a. a foundation wall having a footing;
- b. a subterranean panel drain comprising a unitary member having a top edge, a bottom edge, and first and second sides, said unitary member having a transverse cross-section defining a plurality of alternately disposed ridges and valleys on said first side and said second side respectively, the ridges on said first side corresponding to the valleys on said second side and the ridges on said second side corresponding to the valleys on said first side, said valleys defining a plurality of substantially vertically disposed fluid-flow channels extending between said top edge and said bottom edge, and a plurality of openings disposed in said ridges on said first side to communicate with the corresponding channels on said second side;
- c. said unitary member bottom edge being disposed on said foundation wall footing such that the ridges on said second side of said member are in abutting contact with said foundation wall;
- and
- d. back-fill soil disposed adjacent said first side of said member whereby moisture in said back-fill soil adjacent said first side is capable of flowing through said openings, entering said corresponding channels on said second side, and being directed along said corresponding channels toward said bottom edge of said member.
