Good Year Tire Case Studies
Situation: The Goodyear Tire & Service Network was in the process of installing
an automobile lift into the slab of a repair center. The installation
contractor saw-cut a 5 ft. x 8 ft. rectangle opening in the floor to excavate
soils and install a Rotary brand hydraulic lift. The hole was dug out
with a backhoe and set aside. The ground appeared to be solid natural
soil. Water from an unknown source began entering the hole. This water
caused dirt located under the adjoining slab to slough off into the hole.
Shortly thereafter, a decision was made not to install the hydraulic lift
as originally planned and to repair the floor.
Solution: Saturated dirt at the bottom of the hole is not capable of supporting
new backfill or concrete slab. The new slab must be supported by solid
ground located under the saturated earth at the bottom of the hole. The
engineer recommended the installation of helical piers that extended through
the saturated earth down into the solid ground below.
Conclusion: The engineer called Michael Seebeck to discuss the situation and singularly
recommend Ram Jack of TN to solve the problem. We submitted a proposal
following the engineer's recommendations and was approved. Work began
immediately, installing two  Ram Jack 2-3/8" single helicals with
preconstruction brackets, filled the hole with 21 tons of #57 gravel,
dowel #4 rebar into exposed edges of existing concrete slab on 18"
cc, installed #4 mat of steel spaced 18" each way prior to pouring
concrete, poured concrete over gravel and preconstruction brackets, and
filled voids under the existing concrete slab adjacent to the hole with
