Abstract

A device for preventing water seepage over a foundation wall of a building, such device having first and second L-shaped members disposed facing each other with the base of one resting on the base of the other with a conduit resting on the upper base for the receipt and direction of water away from the foundation wall.

Claims

1. A device for preventing water seepage over a foundation wall of a building, said foundation wall having an exterior and a top against which gravel is filled to ground level, comprising:

a first L-shaped member having an elongated base having a first end, a second end, a top and a bottom, said elongated base disposed horizontally;

an outer wall extending vertically from said first end of said base, said outer wall being approximately 8 inches in height and positioned against the exterior of the top of said foundation wall;

an elongated lip member having first and second ends, said second end attached to, and extending from, said second end of said base, said lip member disposed upwards at approximately a 45 degree angle to said base; and

a second L-shaped member having;

an elongated base having a first end, a second end, a top and a bottom, said elongated base disposed horizontally and resting on said base of said first L-shaped member;

an outer wall extending vertically from said first end of said base of said second L-shaped member, said outer wall being approximately 6 inches in height; and

an elongated lip member having first and second ends, said second end attached to, and extending from, said second end of said base of said second L-shaped member, said lip member of said second L-shaped member disposed upwards at approximately a 45 degree angle to said base of said second L-shaped member, said second L-shaped member being reversed in position.

2. The device of claim 1 further including a plurality of vertically disposed and spaced apart elongated V-shaped reinforcements defined in said outer walls of said first and second L-shaped members for adding strength thereto.

3. The device of claim 2 further including:

a sheet of plastic disposed against said foundation wall, said sheet of plastic extending downward from above ground level to below said base of said first L-shaped member; and

a conduit having a length and a plurality of apertures defined therein, said conduit extending along said top of said base of said second L-shaped member between said lip and said outer wall thereof, said apertures in said conduit for collecting water passing through said gravel positioned over said device, against said plastic sheet and above said conduit, said conduit for drainage of the collected water to a water collection point along said length of said conduit.
