Our daughter and son-in-law (newlyweds) have just purchased their first home. What is the best way to repair the garage floor where the foundation and floor were poured as one because of it sitting on an inclined landscape? The double car garage floor is severely cracked and uneven. One side of the foundation has a large crack. Is there a way to correct these problems without tearing down the garage and completely taking out the concrete and replacing it? Is there a product on the market that could be used to level the floor and seal the underlying cracks? They are stumped as to who to ask, what to ask and how to go about these necessary repairs to a concrete foundation/ garage floor mess. Any advice or assistance you could provide would be appreciated.
