Abstract: A method of imparting strength to earth in support of a ground surface is disclosed. A bag is placed in the earth under the ground surface, the bag having a first end oriented towards the ground surface, a second end opposite the first end, and a cross sectional contour from the first end to the second end that includes at least one wedge portion extendable laterally into surrounding earth located above and below the wedge portion when the bag is filled. A expandable polymeric resin is injected into the bag to at least partially fill the bag to compress earth around the bag. The expandable polymeric resin may be expandable polymeric resin. A bag is also disclosed for use in imparting strength to earth in support of a ground surface.

Abstract: A system and method of stabilizing and strengthening wall structures constructed with hollow core cementitious blocks that have not been filled with concrete. Relatively small ports are drilled at the grout line every 4-6 courses along the vertical plain of one hollow core and this and every second core is then filled with a high density expanding resin thus filling the core there by providing sufficient strength and rigidity, yet flexibility to the wall structure to withstand significant seismic activity.

Abstract: A system and method of constructing hollow core block walls, either reinforced or not reinforced with a re-designed block and the use of expanding polymer resins system as a filling and binding system replacing the traditional system of binding hollow core blocks with a cementitious mortar or adhesive.

Abstract: A system and method of stabilizing wall structures constructed with hollow core cementitious blocks that have not been filled with concrete. Relatively small cores are drilled along either the upper or lower portion of the wall structure to allow for the insertion of a rigid yet flexible reinforcing rod into the hollow core of the block. Through the same hole and other ports drilled into the hollow core block, high density expanding resin is injected to fully fill and encapsulate the reinforcing bar or rod thereby providing sufficient rigidity to the wall structure to withstand significant seismic activity.

Abstract: A foam delivery system comprises two delivery tubes providing a mixing chamber with a two-part polymeric foam. The mixing chamber mixes the two-part polymeric foam below a ground surface. A delivery manifold with delivery arms discharges the two-part polymer resin from the foam delivery system. A method of distributing a foam delivery systems comprises lowering a foam delivery system below a ground surface and discharging a polymer resin into the ground surface from a mixing chamber located below the ground surface. The mixing chamber discharges the polymer resin while the mixing chamber is lifted towards the ground surface, providing an expanding base of polymer resin. In that the chemicals are mixed at depth, that is, at the depth of the desired injection points, the possibility of premature setting and plugging of the delivery system is negated.

Abstract: In this invention, after a hole has been drilled or excavated, injection probe(s) are placed at appropriate depth(s), the excavated native materials are replaced with appropriately sized crushed rock or other natural or synthetic materials, and then a polymeric resin is injected through the probe(s) to encapsulate and bind the fill material, whereby upon curing the polymeric resin and fill material forms a foam friction pile. Such friction piles drilled or excavated adjacent to each other will form a foam sheet piling system. The foam piles can also be re-enforced using nylon, polypropylene, fiberglass, other synthetic or non-synthetic materials or combinations of these materials. The polymeric resin typically would comprise a high density closed cell, water resistant expanding two component polyurethane foam system.

Abstract: In this invention, after the grade at a construction site has been excavated and/or graded to its preliminary rough grade, re-enforcing material, typically synthetic in nature, such as nylon or polypropylene mesh or rods, fiber-glass rods or mesh, or other specified re-enforcing material is laid across soil at the construction site and a reinforced base is formed by covering the reinforcing material with a polymeric resin, whereby upon curing, the polymeric resin and reinforcing material forms a contiguous thermo-structural base. Re-enforcement material comprising synthetic and/or non-synthetic components in the form of rods, rope, strapping, mesh, netting, geotextile fabrics or other dimensional forms laid longitudinally, or in a grid pattern, in single or multiple layers, tied or not tied all in situ sprayed with a high density closed cell, water resistant expanding two component polyurethane foam system.
