Foundation system

Abstract

A poured concrete slab foundation which has a first component comprising a poured concrete slab on soil, having at least one interior grade beam, grade beams about the periphery of said poured concrete slab, and an array of openings along and adjacent to each said interior grade beam; a second component comprising an array of driven piles in the soil below said interior and periphery grade beams; and a third component comprising poured concrete closures in said openings, which is made by preparing a poured concrete slab on soil, having at least one interior grade beam, grade beams about the periphery of said poured concrete slab, and an array of openings along and adjacent to each said interior grade beam; driving an array of pilings in the soil below said interior grade beams adjacent to the openings and the periphery grade beams and pouring concrete closures in said openings.

1 . A poured concrete foundation comprises a first component comprising a poured concrete slab on soil, having at least one interior grade beam, grade beams about the periphery of said poured concrete slab, and an array of openings along and adjacent to each said interior grade beam; a second component comprising an array of driven piles in the soil below said interior adjacent to said openings; and a third component comprising poured concrete closures in said openings.  
   
   
       2 . The poured concrete foundation according to  claim 1  wherein piling are arrayed about said periphery grade beams.  
   
   
       3 . The poured concrete foundation according to  claim 1  wherein void cartons are position below said first component and said third component.  
   
   
       4 . The poured concrete foundation according to  claim 2  wherein void cartons are position below said first component and said third component.  
   
   
       5 . The poured concrete foundation according to  claim 1  comprising at least one plumbing riser extending through a sleeve embedded in said foundation.  
   
   
       6 . A component of a poured concrete foundation comprising a poured concrete slab on soil, having at least one interior grade beam, grade beams about the periphery of said poured concrete slab, and an array of openings along and adjacent to each said interior grade beam.  
   
   
       7 . A process for making a poured concrete foundation comprising: preparing a poured concrete slab on soil, having at least one interior grade beam, grade beams about the periphery of said poured concrete slab, and an array of openings along and adjacent to each said interior grade beam; driving an array of pilings in the soil below said interior grade beams adjacent to openings and pouring concrete closures in said openings.  
   
   
       8 . The process according to  claim 7  comprising driving an array of pilings in the soil below said periphery grade beams.
