You’ll often see cracks close to the garage door. That’s the area of the floor that’s the most exposed to cold and frost and thus more prone to freezing under the slab. When a garage floor cracks badly due to settlement, it can sink in sections. Or water will pool in one corner due to uneven settling. This can be a big problem if the water gets into your house.

Water can make its way from the attached garage into the house, if the slab has been poured at the wrong height. If the slab was sloped in the wrong direction, water can flow toward the interior walls, down to your basement, or into living space that’s on the same level as the garage slab.

If the garage slab is below grade, water can get in. Check the grade around the garage: Water might be seeping in from the sides or back, not just at the door. Make sure the outside soil level is at least six inches below the level of your garage floor. This isn’t always so easy to see; sometimes the brick veneer, siding or stucco disguises the floor level.

There are ways to fix a bad slab. One affordable option is to re-level the floor by pumping concrete under the slab and raising it and stabilizing the soil at the same time.
