How to Fix Badly Heaved Garage Floors

Heaving of concrete floors occurs when the floor develops cracks that begin to split the floor. Ground settling and temperature changes are just some of the factors that can cause concrete floors to develop cracks. Once your concrete floor heaves, you should repair it as quickly as possible because the cracks can spread rapidly. If the heaving becomes too bad, you will have to replace the floor.
