Potential PhosphoCrete™ Applications

The basis for PhosphoCrete™ is to chemically alter the clays to make them considerably stronger and significantly less compressible.
 

• Foundations for buildings - design assuming that the PhosphoCrete™ layer is acting as a beam under the footing, spreading out the load and distributing it as side friction and end bearing.  For typical one-story buildings, excavate soft clays to the bottom of the layer or to a minimum 6 feet below the footing, and replace with PhosphoCrete™.
   

• Parking lots - for use with asphalt (flexible pavement) with moderate load requirements.  Excavate the clays 2.5 feet below grade, mix in PhosphoCrete™, and replace to provide a reasonably thick layer that will ‘float’ over softer clays and minimize pavement deflection.
   

•  Buried Utilities - To minimize settlement of buried water and sewer pipes, as well as cable, electric, and fiber optic lines crossing soft clays, mix PhosphoCrete™ to form a bed of cemented clays beneath the utilities.  We recommend stabilizing a trench, allowing a few weeks for curing, then excavating the required cross-section within the chemically stabilized soil.  This will minimize differential settlement, and especially reduce installation costs by improving the workability of materials within the excavation.
   

•  Signage and Light Poles -  Stabilize the area beneath and around the base of the pole to reduce vertical settlement and improve lateral stability against overturning moments.  Site-specific designs are required based on height of the poles, loads, and soil conditions.
