  • Patent number: 4893784
    Abstract: An apparatus and method for jacking basement walls which have moved out of alignment due to pressure from outside the wall. The apparatus includes a brace attached at the bottom by a bracket adjacent the wall to be jacked. The brace is then set vertically against the wall. A telescoping beam is attached to the floor a short distance from the wall, so that the beam is positioned upright, parallel to the brace. In one embodiment the upper end of the beam is extended and attached to the floor joists overhead in the basement. In another embodiment the upper end of the beam is secured to the lower surface on which the wall rests. Any suitable jack assembly is then slidably attached between the beam and the brace. The jack assembly is then positioned at the proper point and used to move the wall back into its proper place. Finally the top of the brace is anchored so as to prevent the wall from moving back out of position.

  • Patent number: 4669704
    Abstract: An apparatus and method for jacking basement walls which have cracked or partially moved inward due to pressure from outside the wall. Employing the apparatus of this invention, the jacking operation can be done easily and safely even in basements where there is little space along the wall in which to fit jacking equipment. The apparatus includes a brace attached at the bottom by a bracket adjacent the wall to be jacked. The brace is then set vertically against the wall. A telescoping beam is attached to the floor a short distance from the wall, so that the beam is positioned upright, parallel to the brace. The upper end of the beam is extended and attached to the floor joists overhead in the basement. A jack assembly is then slidably attached between the beam and the brace. The jack assembly may then be slid to the proper point to exert pressure on the brace, and in turn the wall, at the best possible spot.
