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 pozzolan and granular material such as sand.
1. A system to improve building foundation site soil moisture stability, comprising;
a water permeable soil moisture stabilization material that improves the soil's ability to retain and transport moisture;
at least one zone at the building foundation site that comprises a liquid delivery means for delivering liquid to a liquid distribution means, wherein the building foundation on the building foundation site has a surface and an outside edge;
a liquid distribution system comprising a trench or hole(s) disposed on the building foundation site, the trench or hole(s) containing the water permeable soil moisture stabilization material disposed adjacent the foundation; and
a liquid retarding barrier placed on at least one side of the trench or hole(s).
2. The system of claim 1 wherein the liquid distribution system comprises holes containing the moisture stabilization material placed in the soil on the building foundation site.
3. The system of claim 1 wherein the soil moisture stabilization material is placed in water permeable containers on the building foundation site.
4. The system of claim 3 comprising a section of liquid delivery conduit disposed in and at the top of the water permeable containers.
5. The system of claim 1 wherein the water permeable soil moisture stabilization material comprises the mineral pozzolan.
6. A system to improve a building foundation site soil moisture stability, comprising;
a water permeable soil moisture stabilization material that improves the soil's ability to retain and transport moisture, and
comprising a controllable liquid delivery means to supply moisture to the soil moisture stabilization material comprising a water source and conduit for delivery, wherein the liquid delivery means is controlled by controllers activated directly or remotely utilizing criteria from the group consisting of preset intervals, moisture level of the soil in the vicinity of the section, annual season and rainfall.
7. The system of claim 6 wherein the liquid delivery means is controlled by connection of the controller to the internet, satellite, or by text message from a wireless phone or tablet, telephone line or cable, homeowners association network or other community organization.
8. A system to improve a building foundation site soil moisture stability, comprising;
a water permeable soil moisture stabilization material comprising the mineral pozzolan that improves the soil's ability to retain and transport moisture;
a controllable liquid delivery means to supply moisture to the soil moisture stabilization material comprising a water source and conduit for delivery, and identifying markers placed in the soil moisture stabilization material selected from the group consisting of RFID chips, tags, small unique plastic pieces, beads, and distinctive granular material.
9. The system of claim 8 wherein the identifying markers are RFID chips.
10. A method for stabilizing the moisture content of soil located on a building site, the soil having a surface and a subsurface and a moisture content, the method comprising: applying a water permeable soil moisture stabilization material to improve the soil's ability to retain and transport moisture, said stabilization material located adjacent a building foundation, and placing a liquid retardant barrier adjacent the location of the moisture stabilization material.
11. The method of claim 10 wherein the liquid distribution system comprises a plurality of sections and wherein liquid flow to each section is controlled.
12. The method of claim 10 wherein the distribution system comprises a plurality of sections and wherein liquid flow to each section is controlled by controllers activated directly or remotely utilizing criteria selected from the group consisting of preset intervals, moisture level of the soil in the vicinity of the section, annual season and rainfall.
13. The method of claim 10 wherein soil moisture stabilization material comprises the mineral pozzolan disposed in a granular material in a concentration of about 10 to 50 percent.
14. The method of claim 10 wherein the soil moisture stabilizing material is disposed on top of, mixed with or under the surface of the soil of a building site.
15. The method of claim 10 comprising the mineral pozzolan mixed with granular material, sand or indigenous soil to stabilize the soil.
16. The system of claim 10 wherein the water permeable soil moisture stabilization material comprises the mineral pozzolan.
