Abstract

A drainage system is located in a trench formed about the inner periphery of a foundation. The drainage system comprises a plurality of interconnected pipes, each positioned and pitched to allow water entering the pipes to flow to a collection site. The pipes comprise a longitudinal tubular member having a top wall with a central section containing a plurality of apertures. The top wall has a first sloping section which slopes from one end towards the central portion at a given angle and slopes from the other end towards the central portion at the same angle to enable any water directed on the top surface to flow into the apertures on the central portion of the pipe. The member contains a bottom wall and first and second side walls. A first side wall has a plurality of apertures and is positioned against the foundation wall. The second side wall is devoid of apertures as is the bottom wall. The side walls are each of the same height. When the member is positioned within the trench, the apertures in the top surface and the side wall in contact with the foundation wall cause water to flow through the pipe structure and to be directed towards the collection site.

Claims

1. A drainage system for a foundation, comprising:

(a) a basement wall extending along a basement floor,

(b) a trench extending along the inner periphery of said wall and located between said wall and said floor,

(c) a first unitary longitudinal tubular member positioned in said trench, said member having a top wall, a bottom wall and first and second side walls, with said top wall having a central region containing a plurality of apertures, with said central region communicating with the edges of said top wall by first and second sloping portions to enable water directed on said top wall to flow towards said central region and only said first side wall having a plurality of apertures with said first side wall positioned in abutting relation with said basement wall, said tubular member as positioned in said trench being sloped to cause any water entering the hollow confines of said member via said apertures in either said top surface or said side walls to flow towards a collection site.

2. The drainage system according to claim 1 wherein said longitudinal tubular member is fabricated from plastic.

3. The drainage system according to claim 1 wherein said top surface of said tubular member is of a "V" cross-section, with said apertures positioned at the bottom central portion of said "V".

4. The drainage system according to claim 1 wherein said top surface of said tubular member is of a "U" shaped cross-section with said apertures positioned at the base of said "U" defining a central region.

5. The drainage system according to claim 1 wherein said top surface of said tubular member comprises a flat planar region centrally located and having a plurality of apertures positioned thereon, with a right side sloping downwardly towards said central region from a first edge and a left side sloping downwardly towards said central region from a second edge.

6. The drainage system according to claim 1 wherein said bottom wall is at a slight angle with respect to said first side wall to cause water entering the apertures in said first said wall to be directed towards said second side wall.

7. The drainage system according to claim 1 including a second longitudinal tubular member of an exact configuration as said first tubular member, and means for coupling said first and second members together.

8. The drainage system according to claim 1 wherein said side walls are of a height between two to three inches.

9. A method of providing a drainage system for a foundation, comprising the steps of:

(a) forming a trench about the inner periphery of the foundation wall,

(b) inserting a plurality of longitudinal tubular members within said trench and about said periphery of said inner wall, said members having a top surface of a recessed configuration to cause water to flow towards the center of said top surface,

(c) forming a series of apertures in the center of said top surface of said tubular member,

(d) forming a plurality of apertures on a side wall of said tubular member;

which side wall is in abutting relation with said foundation wall,

(e) sloping said tubular members towards a collection site whereby any water entering said apertures is directed to flow via the hollow confines of said tubular members towards said collection site.

10. The method according to claim 9 wherein said tubular members are fabricated from plastic.
