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 aluninosilicate Pozzolan mineral and granular material such as sand.

An integral geogrid includes a plurality of interconnected, oriented strands having an array of openings therein that is produced from a coextruded multilayer polymer sheet starting material. By virtue of the construction, the coextruded multilayer sheet components provide a crystalline synergistic effect during extrusion and orientation of the integral geogrid, resulting in enhanced material properties that provide performance benefits to use of the integral geogrid in soil geosynthetic reinforcement.

Described herein are tools, systems and methods for conditioning, strengthening and/or improving in situ soil geotechnical or agricultural properties while at least temporarily reducing soil density, energy requirements, and tool wear.

A milling machine has a frame, a rotor, a mixing chamber with a front door and a rear door, and a controller. The controller is in communication with the frame, the rotor, the front door, and the rear door, and configured to operate the milling machine in a travel mode and a work mode. When the travel mode is actuated, the controller raises the rotor to a predetermined position, closes the front door and the rear door, and raises the frame to a predetermined height. When the work mode is actuated, the controller lowers the frame to a predetermined height, lowers the rotor to a predetermined position, and opens the front door and the rear door to predetermined positions.

A silt barrier support system broadly comprising a number of vertically extending posts, a number of silt barrier attachment devices, a number of end silt barrier attachment devices, and an inward silt barrier attachment device. The silt barrier attachment devices include vertical barbs for vertically retaining portions of an upper end of a geotextile fabric layer on upper portions of the posts. The end silt barrier attachment devices include horizontal barbs for laterally retaining end portions of the geotextile fabric layer on end posts. The inward silt barrier attachment device includes first and second sets of horizontal barbs for removing lateral slack from inward portions of the geotextile fabric layer.

A method and composition for reducing the swelling capacity of clay-containing soil, thus lowering volume change in soil, and thus enhancing the stability of soil, particularly expansive clay soil, in order that it is sufficiently stable, such that roads, pavements and some types of buildings and other structures can be securely constructed thereon. The method also minimizes any swelling and/or shrinkage in the soil under any such structures due to the movement of moisture in the soil, and thus minimizes damage and deterioration caused to such structures due to the presence of too much, or too little, water in the soil thereunder.

A geomaterial web includes a first organic structural material and a second structural material that is different from the first structural material, which is bonded together with the first structural material to form a sheet-like composite material web extending in two mutually perpendicular directions. The first structural material and the second structural material are organic materials, where the first structural material has a first biodegradability and the second structural material has a second biodegradability that is different from the first biodegradability. The second biodegradability may be less than the first biodegradability.
