Building foundation and soil stabilization method and system
System and means soil stabilization and moisture control for building foundations including methods and systems for stabilization moisture in a site for building foundation by applying soil moisture stabilization material in various forms, a preferred stabilization material being a mixture of aluminosilicate Pozzolan mineral and granular material such as sand.
1. A method, the method comprising:
forming, prior to forming or placing a foundation at a foundation location, one or more volumetric spaces under the foundation location, wherein said forming comprises:
creating one or more vertical volumetric spaces, and
placing a capillary conductive medium fill in the vertical volumetric spaces;
installing, prior to forming or placing the foundation at a foundation location, a fluid delivery system configured to deliver a fluid to the one or more vertical volumetric spaces under the foundation location, wherein said installing comprises installing horizontal fluid conduits to deliver the fluid to respective ones of the vertical volumetric spaces.
2. The method as recited in claim 1 , further comprising:
applying a soil moisture stabilization material to the one or more volumetric spaces.
3. The method as recited in claim 1 , wherein installing the fluid delivery system comprises:
installing, prior to forming or placing the foundation at the foundation location, conduits from one or more supply ends to one or more of the volumetric spaces, wherein the conduits are configured to transport a fluid from the one or more supply ends to respective volumetric spaces.
4. The method as recited in claim 1 , wherein
said installing the fluid delivery system comprises installing PVC pipe or drip irrigation tubing to supply the fluid to the volumetric spaces.
5. The method as recited in claim 1 ,
wherein said installing the fluid delivery system comprises installing one or more vertical tubes coupled to the horizontal fluid conduits to deliver the fluid to respective ones of the vertical volumetric spaces, and
wherein the vertical tubes comprise perforated vertical tubes with capped ends.
6. The method as recited in claim 1 , wherein
said forming one or more volumetric spaces comprises creating one or more vertical holes, and placing a sand or gravel fill in the holes; and
said installing the fluid delivery system comprises installing one or more vertical tubes coupled to the horizontal conduits to deliver the fluid to respective ones of the vertical holes, wherein the vertical tubes comprise perforated vertical tubes.
7. The method as recited in claim 1 , wherein
said forming one or more volumetric spaces comprises creating one or more vertical holes, and placing a sand or gravel fill in the holes; and
said installing the fluid delivery system comprises terminating one or more horizontal conduits above the one or more vertical holes to deliver the fluid to respective ones of the vertical holes.
8. The method as recited in claim 1 , wherein said installing the fluid delivery system configured to deliver a fluid to the one or more volumetric spaces under the foundation location comprises installing perforated pipe under the foundation location.
9. The method as recited in claim 1 , further comprising:
installing the foundation at the foundation location, wherein the foundation is installed, at least partially, over the one or more volumetric spaces.
10. A method, the method comprising:
preparing, prior to installing a foundation at a foundation site, the foundation site with a soil moisture stabilization system, preparing comprising:
forming in the foundation site, below a location for the foundation, one or more vertical volumetric spaces configured to provide a reservoir of moisture for the soil surrounding the one or more vertical volumetric spaces, the volumetric spaces comprising a capillary conductive medium fill material; and
installing a fluid distribution system comprising horizontal fluid conduits configured to transport a fluid from a source to the capillary conductive medium in the one or more vertical volumetric spaces configured to provide the reservoir of moisture for the soil surrounding the one or more vertical volumetric spaces at the foundation site.
11. The method as recited in claim 10 , wherein:
said forming one or more vertical volumetric spaces below the location for the foundation comprises forming one or more holes in the soil at the foundation site; and
said installing the fluid distribution system comprises:
locating one or more pvc pipes in the one or more holes; and
filling the one or more holes with the capillary conductive medium.
12. The method as recited in claim 10 , wherein
said forming the one or more volumetric spaces in the foundation site comprises forming a plurality of vertical holes in the foundation site.
13. The method as recited in claim 10 , wherein
said installing the fluid distribution system comprises installing PVC pipe or drip irrigation tubing to transport the fluid to the volumetric spaces.
