We contemplated doing this for about 8 months! We had a dip on one side of the garage floor that was about 3″. After all the research and cost comparison to jack hammer and re-pour a new garage floor, we finally decide to move forward with Slab Jack. Why didn’t we do this 8 months ago? The team came on time, answered question I had and I watched them throughout the whole process. They were careful, efficient and cleaned up (all within an hour). Thank you Slab Jack team!
