ABSTRACT:
This invention relates to the draining of foundations by using an elongate subterranean drainage structure located approximately horizontally and parallel to the foundation in combination with a plurality of elongate upwardly extending hollow drain structures extending from the structure toward the surface of the earth. Hydrostatic pressure of water in the soil forces water through holes in the upwardly extending drain structures. The water then passes rapidly to the bottom of the upwardly extending drain structures by the force of gravity and thereupon into the horizontal drain structure wherein it is carried away from the foundation.
