Specializing in garage floor repair and concrete floor replacement. www.minipepine.com Garage floors take a lot of abuse.
They have to support your heavy car, resist ice, dirt, road salt, gasoline, motor oil, antifreeze, and other contaminants. Since few garages are heated, they have to tolerate freeze/thaw conditions. But a garage slab that has been carefully planned, installed, and cured should have no trouble providing years of crack-free performance in any climate, even under the toughest conditions.
It is important to start with a good base. In most cases the soil under your garage floor was disturbed and not sufficiently compacted after the excavation for your homes foundation.
Over time the ground settles, potentially causing the slab to crack and heave. Gaps between your base and concrete floor can also occur and cause poor drainage, water pooling, humidity and moister in your garage.
