Drainage system for use in basements and a method for its installation and use

Abstract

A basement drainage system and method for its use comprising a combination of floor drains, poly drains and an exterior drainage system, wherein the exterior drainage system and poly drains can prevent water from entering the basement and wherein one or more floor drains can each transport water to one or more sump basins to be pumped out of a basement and away from a building. The present basement drainage system can effectively remove ground water located below a basement floor as well as water collected on the surface of the basement floor, and prevent ground water from entering the basement.

What is claimed is: 
     
         1 . A basement drainage system, comprising:
 a basement having walls at its perimeter and a basement floor located in the area within the walls;   at least one sump basin located within the basement and located partially below the basement floor;   at least one sump pump located within the sump basin;   a poly drain placed in the basement, along the walls, and below the basement floor connected to the sump basin;   an outer floor drain placed in the basement and along the perimeter of the walls and connected to the sump basin; and   an upper exterior drainage system located outside of the basement and along the outer perimeter of the basement wall.   
     
     
         2 . The basement drainage system as recited in  claim 1 , comprising a lower exterior drainage system located outside of the basement and along the outer perimeter of the basement wall and below the upper exterior drainage system. 
     
     
         3 . The basement drainage system as recited in  claim 1 , wherein the poly drain is a perforated drain hose made from a polymer. 
     
     
         4 . The basement drainage system as recited in  claim 1 , wherein the top of the outer floor drain is level with the top of the basement floor. 
     
     
         5 . The basement drainage system as recited in  claim 1 , wherein the upper exterior drainage system comprises a perforated pipe surrounded by pebbles and covered with topsoil. 
     
     
         6 . A basement drainage system, comprising:
 a basement having walls at its perimeter and a basement floor located in the area within the walls;   at least one sump basin located within the basement and located partially below the basement floor;   at least one sump pump located within the sump basin;   a poly drain placed in the basement, along the walls, and below the basement floor connected to the sump basin;   an outer floor drain placed in the basement and along the perimeter of the walls and connected to the sump basin;   an inner floor drain placed in the basement and along the perimeter of the walls, and within the outer floor drain, and connected to the sump basin;   an upper exterior drainage system located outside of the basement and along the outer perimeter of the basement wall; and   a lower exterior drainage system located outside of the basement and along the outer perimeter of the basement wall and below the upper exterior drainage.   
     
     
         7 . The basement drainage system as recited in  claim 6 , wherein the lower drainage system comprises a vent pipe. 
     
     
         8 . The basement drainage system as recited in  claim 6 , wherein the poly drain is a perforated drain hose made from a polymer. 
     
     
         9 . The basement drainage system as recited in  claim 6 , wherein the tops of both the inner and outer floor drains are level with the top of the basement floor. 
     
     
         10 . The basement drainage system as recited in  claim 6 , wherein the upper exterior drainage system and the lower exterior drainage system each comprise a perforated pipe surrounded by pebbles and covered with topsoil. 
     
     
         11 . A method for installing and using a basement drainage system, the method comprising:
 providing a basement drainage system, comprising: a basement having walls at its perimeter and a basement floor located in the area within the walls; at least one sump basin; at least one sump pump; a poly drain; an outer floor drain placed in the basement and along the perimeter of the walls and connected to the sump basin; and an upper exterior drainage system located outside of the basement and along the outer perimeter of the basement wall;   placing at least one sump basin in a basement floor, wherein the sump basin is located partially below the surface of a the basement floor;   placing at least one sump pump into at least one sump basin, wherein the sump pump can transport water from the sump basin out of the basement;   placing at least one poly drain constructed to drain water to at least sump basin using gravity, wherein one or more poly drains constructed to drain ground water located below the basement floor to one or more sump basins using gravity, where it can be pumped out of placing an outer floor drain along the inner perimeter of a basement wall constructed to drain water to at least one sump basin, this outer floor drain being capable of collecting water located on the surface of the basement floor;   placing an inner floor drain located along the inner perimeter of the outer floor drain constructed to drain water to at least one sump basin, this inner floor drain being capable of collecting water located on the surface of the basement floor; and   placing at least one exterior drainage system along the outer perimeter of the basement wall, wherein the exterior drainage system is capable of draining water to lower ground or a water drainage system.   
     
     
         12 . The method as recited in  claim 11 , wherein the poly drain is a perforated drain hose made from a polymer. 
     
     
         13 . The method as recited in  claim 11 , wherein the top of the inner floor drain is level with the top of a basement floor. 
     
     
         14 . The method as recited in  claim 11 , wherein the top of the outer floor drain is level with the top of a basement floor. 
     
     
         15 . The method as recited in  claim 11 , wherein the inner floor drain is located above a foundation. 
     
     
         16 . The method as recited in  claim 11 , wherein the outer floor drain is not located above a foundation. 
     
     
         17 . The method as recited in  claim 11 , wherein the installation of the exterior drainage system comprising:
 making a longitudinal cut in the ground parallel to the basement wall;   placing a perforated pipe inside the cut;   filling up the cut with pebbles; and   placing top soil on top of the pebbles and perforated pipe.
