Abstract

A drainage device for building foundations is provided, composed of a tubular structure having apertures in its upper and side surfaces and a drainage orifice at one end thereof. The device is sized to permit installation between segments of the building material forming the foundation and may be surrounded by mortar. Water percolating through the foundation is collected via the apertures and drained away from the foundation through the tubular structure. Any number of such drainage devices may be installed during construction of the building foundation.
