Basement wall structure to prevent water leakage

DETAILED DESCRIPTION OF THE INVENTION The basic unit comprising the invention is shown in the perspective combined diagrams of FIGS.
1 and 2, and is generally depicted by the numeral 10.
It encompasses a flat outer surface 12 with closed ends 14 and 16, and a plurality of extending ribs 18 which define generally U-shaped sections 20, such ribs 18 extending away from the face 12.
A portion of the unit 10 extending from outer surface 12 to the ribs 18 effectively forms a sealed outer skin to the ground.
It should be understood that the unit 10 can be either molded or extruded from a light weight material such as a polystyrene foam, or that it might be reinforced appropriately, but in any event, it is simple and inexpensive to make and is relatively light weight, particularly with all of the channels 20 and the reinforcing ribs 18 forming a good structural base to support the face 12 away from the basement wall as will be more fully defined hereinafter.
FIG.
2 illustrates the cap indicated generally by numeral 21 which comprises a sloped top surface 24 and bottom edges 26 that will fit on top of the upper surface 22 of unit 10, and be adhesively secured thereto in a water tight fit.
The back surface 28 likewise coincides with the ends of the respective ribs 18 at the ends of unit 10, and combine an overall extension that when adhesively secured to the wall of the basement forms a water tight closure therewith.
Turning now to the cross sectional top view configuration of FIG.
3, the numeral 30 indicates a conventional cinder block or concrete block wall that is built on to a footer 32, and includes the conventional drain tile 34 that is surrounded by soil 36 in a conventional manner.
The block wall 30 also has an outside sealing layer 38 normally associated therewith which may be tar, or some other water sealant coating that is required by normal building codes.
In other words, the block wall 30 is built in exactly the conventional manner to that normally defined for basement construction by most building codes
