Abstract
A drainage system for draining water away from a building having a horizontal base and walls extending vertically from the base. The drainage system includes first drain means located in a first trench provided in the ground beneath the base inside the perimeter thereof. The first trench extends around the perimeter of the base and inside of the vertically extending walls. Second drain means is located in a second trench provided in the ground adjacent the ground surface and adjacent the perimeter of the horizontal base. The second trench extends around the perimeter of the horizontal base and outside of the vertically extending walls. A gravel filling is provided in the first and second trenches and covers at least partially the first and second drain tiles.

A drainage system for draining water away from a building located in ground having a surface above which a portion of the building extends, the building having a horizontal base lying adjacent the ground and walls extending vertically from said base, said system including first drain means located in a first trench provided in the ground beneath said base adjacent the perimeter thereof, said first trench extending around at least a portion of the perimeter of said base and inside of said vertically extending walls, second drain means located in a second trench provided in the ground, said first and second drain means being independent of each other whereby said second drain means does not communicate with said first drain means, said second trench extending around at least a portion of the perimeter of said walls and outside of said vertically extending walls, said second trench being at least about 14 inches wide and about 18 inches deep and not greater than about three feet deep, said base being substantially deeper in the ground than said second drain means, said second trench being lined with a plastic sheet to form a trough for capturing water flowing from the ground surface into said second trench and for preventing water from flowing downwardly along said walls, said second drain means comprising pipe means for receiving water captured in said trough and for conducting said water away from said building, and gravel filling said first and second trenches and covering at least partially said first and second drain means.
A drainage system for draining water away from a building located in ground having a surface above which a portion of the building extends, the building having a horizontal base lying adjacent the ground and walls extending vertically from said base, said system including first drain means located in a first trench provided in the ground beneath said base adjacent the perimeter thereof, said first trench extending around at least a portion of the perimeter of said base and inside of said vertically extending walls, second drain means located in a second trench provided in the ground, said first and second drain means being independent of each other whereby said second drain means does not communicate with said first drain means, said second trench extending around at least a portion of the perimeter of said base and outside of said vertically extending walls, said second trench being at least about 14 inches wide and about 18 inches deep and not greater than about three feet deep, said base being substantially deeper in the ground than said second drain means, said second drain means comprising pipe means for receiving water and for conducting said water away from said building, and gravel filling said first and second trenches and covering at leat partially said first and second drain means.
A drainage system for draining water away from a building located in ground having a surface above which a portion of the building extends, the building having a horizontal base lying adjacent the ground and walls extending vertically from said base, said system including first drain means located in a first trench provided in the ground beneath said base adjacent the perimeter thereof, said first trench extending around at least a portion of the perimeter of said base and inside of said vertically extending walls, second drain means located in a second trench provided in the ground, said second trench extending around at least a portion of the perimeter of said walls and outside of said vertically extending walls, said second trench being at least about 14 inches wide and about 18 inches deep and not greater than about three feet deep, said second trench being lined with a plastic sheet to form a trough for capturing water flowing from the ground surface into said second trench and for preventing water from flowing downwardly along said walls, said plastic sheet being secured to the exterior of said walls at approximately the level of the surface of the ground, said second drain means comprising pipe means for receiving water captured in said trough and for conducting said water away from said building, gravel filling said first and second trenches and covering at least partially said first and second drain means, said walls being formed of hollow building blocks and provided with openings in the bottom portion thereof for conducting moisture that penetrates inside of said blocks to said first trench, said drainage system further including an expansion plate located between the inside surface of said wall and a side end surface of the base adjacent said walls, said expansion plate having notches formed in the lower portion thereof for conducting water therethrough to said first trench, said gravel in said first trench engaging portions of said expansion plate above the level of said notches, and a perforated plastic sheet covering said gravel in said second trench.
A method of draining water away from a building in ground having a surface above which a portion of the building extends, the building having a horizontal base lying adjacent the ground and walls extending vertically therefrom, said method including the steps of:
- providing a first trench in the ground beneath said base adjacent the perimeter thereof and extending around said perimeter and inside of said walls,
- placing first drain means in said first trench,
- providing a second trench in the ground at least about 14 inches wide and about 18 inches deep and not greater than about three feet deep and outside of said walls,
- placing second drain means in said second trench substantially above the level of said base, said first and second drain means being independent of each other whereby said second drain means does not communicate with said first drain means, and
- filling said first and second trenches with gravel.
