A nut is welded to the stud leaving about ½ inch of the stud protruding upwards for insertion into the socket. The nut may be turned to adjust the height of the stud. The shim-block and coupling assembly are supported by a head plate which is supported by the pier. The head plate includes a wide table for supporting a pair of jacks on opposite sides of a house jack facilitating installation of the system. The cooperation of the ball and socket helps to prevent “off-set loads” which otherwise may break the piering system. | 07-01-2010 |

| 20110020068 | Height-Adjustable, Structurally Suspended Slabs for a Structural Foundation - To form a new structurally suspended slab or to raise an existing slab for a structural foundation, structural supports are placed in the ground. The structural supports are attached to lifting assemblies, which are also installed in the slab. Actuation of the lifting assembly allows the slab to be raised and/or lowered, thereby forming a suspended slab over a void of a desired size. Existing slabs may be repaired using similar techniques. | 01-27-2011 |
| 20110116873 | System for Forming a Movable Slab Foundation - A system for forming a movable slab foundation has a slab foundation, a support pier, and a housing positioned within the support pier. A support sleeve is positioned within and is substantially surrounded by the housing. Portions of the support sleeve are encased within the slab foundation. The support sleeve is capable of axial movement relative to the housing. A guide plate is connected to the lower end of the support sleeve. A cavity is defined by the space between the guide plate and the lower end of the housing. A port is located in and extends through the guide plate and into the cavity. The slab foundation, the support sleeve, and the guide plate are raised to a desired height relative to the housing. The cavity is filled with support media through the port to secure the position of the slab foundation, the support sleeve, and the guide plate. | 05-19-2011 |
| 20110129306 | EXCAVATION TOOL ASSEMBLY - The invention relates to an excavation tool assembly comprising a housing having a base and an excavation tool having a tool shaft connected to the assembly and extending downwards from the base at an angle, the assembly further comprising a connector portion for attachment to a mechanical power source. | 06-02-2011 |
| 20120114423 | METHOD AND SYSTEM FOR RAISING A BUILDING STRUCTURE - A method of raising a building structure ( | 05-10-2012 |
| 20120155968 | CONSTRUCTION METHOD OF CELLAR FOR BUILDING COMPLETED - Disclosed is a construction method of a cellar for a building completed. The construction method includes fixing supporting structures to bottom concrete of the building; installing a press-in machine on the supporting structures; inserting posts for supporting the building into the foundation under the building by inserting hollow piles into the holes to then insert the piles into the underground using the press-in machine, stacking new piles on the inserted piles, and sequentially inserting the piles using the press-in machine; excavating a foundation under the bottom concrete of the building to prepare an underground space when the building is supported by the posts; and placing the concrete on the horizontal and vertical faces of the underground space prepared by the excavating the bottom concrete of the building. | 06-21-2012 |
| 20140255105 | STRUCTURE LIFTING METHOD AND APPARATUS - A method of lifting a structure using one or more inflatable hoses is described. In one embodiment, a method of lifting a structure resting on the ground includes attaching a lift apparatus to the structure to the raised. An inflatable hose is introduced underneath the lift apparatus, with the inflatable hose being disposed between a bottom surface of the lift apparatus and the ground. The structure is then lifted by inflating the hose with pressurized media so that the hose increases in volume to impose an upward force on the lift apparatus which in turn lifts the structure. | 09-11-2014 |
| 20140356075 | DEEP PILE FOUNDATION CONSTRUCTION METHODOLOGY FOR EXISTING AND NEW BUILDINGS - A method is provided for using low-overhead equipment to construct a deep piling foundation for an existing building. The method involves lifting the existing building to a predetermined elevation above grade and positioning cribbing stacks to support the existing building at the predetermined elevation above grade. The cribbing stacks are spaced from each other enabling low-overhead equipment to maneuver underneath the elevated building to drill drive pipe piles at designated locations to provide optimal support for the building. Grout is pumped under pressure into the pipe piles continuously during the drill driving of the pipe piles so that grout exits through a grout port to mix with disturbed soil about the pipe pile to encase the pipe pile in a grout-soil mixture. Pile caps are attached to each pipe pile and secured to the existing building so that the existing building is supported by an array of the deeply driven pipe piles which serve as the foundation for the building. | 12-04-2014 |
