Novel surface structures and methods thereof

Abstract

A novel foundation system, method of manufacture and method of implementation are disclosed, comprising a simplified cast structure/pile combination advantageously shaped for selective positioning in different soil conditions to become a supporting foundation. In at least one aspect, the shape comprises a cavity or shaped recess that is initially empty, and operable to accept soil displaced by soil heave. The cavity preferably is configured to have a depth estimated to be equal to or greater that an estimated vertical heave displacement of a given site soil, in order to minimize soil heave displacement of the cast structure/pile combination. In at least one other aspect, the shape comprises a portion configured to cleave soil if the soil heaves.

1 . (canceled)  
   
   
       2 . A foundation support system comprising a form means configured to receive a cementitious material in a fluid form for subsequent curing, 
 (a) said form means dimensioned so that said cementitious material, after it has cured, is configured on a lower portion so as to allow the cured cementitious material to cleave soil if said soil heaves; or    (b) said form means comprises a cavity dimensioned to have a depth estimated to be equal to or greater than an estimated vertical heave displacement of said soil.    
   
   
       3 . A system as in  claim 2 , wherein said lower portion has an inverted wedge shape.  
   
   
       4 . A system as in  claim 2 , wherein said lower portion has a pyramidal shape.  
   
   
       5 . A foundation support system comprising a form means configured to receive a cementitious material in a fluid form for subsequent curing, 
 (a) said form means dimensioned so that said cementitious material, after it has cured, is configured and adapted on a lower portion so as to cleave soil if said soil heaves; or    (b) said form means comprises a cavity with a triangular cross-sectional shape.    
   
   
       6 . A foundation support system as in  claim 5 , wherein said cavity is dimensioned to have a depth estimated to be equal to or greater that an estimated vertical heave displacement of said soil.  
   
   
       7 . A system as in  claim 2 , wherein said cavity has a wedge shape.  
   
   
       8 . A system as in  claim 2 , wherein said cavity has a pyramidal shape.
