Abstract
Abstract An arrangement for preventing seepage through a wall from running onto the poured concrete floor of a basement or the like, comprises a vertical channel member positioned between the wall and the floor and having spaced flat surfaces spaced from the wall, and a water impermeable facing strip abutting the flat surfaces which are spaced from the wall and against which the concrete floor is poured. A horizontal channel member has spaced flat surfaces abutting a footing which supports the walls, and alternate spaced flat surfaces spaced from the footing. The concrete floor is poured directly on the horizontal channel member.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
153 words
A seepage control arrangement for preventing seepage water from running over the floor of basements or the like which include vertical side walls resting on a transverse footing, a portion of which extends inwardly from each respective side wall, and a poured concrete floor, the arrangement comprising: a plurality of contiguous unitary structures, each structure including a vertical leg defining sequential vertical drainage channels between the floor and the walls, and a horizontal leg defining sequential horizontal drainage channels between the floor and the footing, each horizontal drainage channel communicating with a corresponding vertical drainage channel to afford egress for water seeping through the walls and to conduct the water beneath the floor, and a separate flat, water impermeable facing strip positioned between the floor and the vertical leg and extending to a height above the height of the vertical leg and the floor to prevent overflow of seepage water onto the floor.
Claim 2
Dependent Claim
153 words
A seepage control arrangement for preventing seepage water from running over the floor of basements or the like which include vertical side walls resting on a transverse footing, a portion of which extends inwardly from each respective side wall, and a poured concrete floor, the arrangement comprising: a plurality of contiguous unitary structures, each structure including a vertical leg defining sequential vertical drainage channels between the floor and the walls, and a horizontal leg defining sequential horizontal drainage channels between the floor and the footing, each horizontal drainage channel communicating with a corresponding vertical drainage channel to afford egress for water seeping through the walls and to conduct the water beneath the floor, and a separate flat, water impermeable facing strip positioned between the floor and the vertical leg and extending to a height above the height of the vertical leg and the floor to prevent overflow of seepage water onto the floor.
Claim 3
Dependent Claim
31 words
The arrangement of claim 1, wherein the contiguous drainage channel structures comprise a plurality of sections in end-to-end abutting relationship, and the facing strip comprises a separate continuous unitary flexible strip.
Claim 4
Dependent Claim
27 words
The arrangement of claim 1, wherein the horizontal and vertical legs defining the drainage channels comprise two legs, at right angles to each other, of separate structures.
Claim 5
Dependent Claim
84 words
The arrangement of claim 1, wherein said unitary structures comprise elongated, rigid panels having sequential, transverse interconnected ridges and valleys, the bottoms of the valleys and the tops of the ridges being flat, the flat valleys of the vertical leg being disposed to abut the side walls, and the flat valleys of the horizontal leg being disposed to abut the footing, the flat ridges of said legs being spaced from the side walls and footing respectively so as to form therewith said drainage channels.
