An uneven garage floor can look alarming. The first step is distinguishing a slab elevation problem from movement affecting the building’s support.
A floor is not automatically the foundation
Many garage floors are slabs on the ground, but construction varies. A crack or low spot by itself does not tell you which components are affected. Photos can start a conversation; they cannot establish a structural diagnosis.
Describe changes around the slab
Mention doors that have changed operation, visible wall movement, earlier repairs, water issues and where the slab meets the perimeter. These observations help the evaluating professional decide whether the issue is within the lifting scope or needs another type of investigation.
Ask for the boundary of the proposed repair
If mudjacking is proposed, the scope should identify the concrete being lifted, the intended profile and any limitations. Ask about buried utilities, adjacent structures and existing surface damage. Do not assume a slab lift repairs structural footings, walls or every cause of movement.
Know when to bring in another professional
Recurring settlement, broader ground movement or structural concerns may require an engineer or geotechnical specialist. The Utah Geological Survey offers guidance on obtaining property-specific information and checking professional licenses. Randy’s mudjacking service should not be represented as engineering or structural foundation repair.
