2 X 4 lumber holding up main beam under garage
This is a grossly undersized support for something as heavy as a garage floor that has two cars on top.

Garge over room in basement
Would you park your car on something that was support by 2x4" lumber?

Large footing with steel plate
Earlier, a large cast-in-place footing was poured under the concrete floor. Once the footing cured, the Smartjacks could be installed. Here a large steel plate goes on top of the cast in place footing

Top plate
The SmartJack XT is connected to a large top plate which goes directly under the main beam.

Floor re-concreted.
After the install is compilate, the floor is re-finished back to original height.
