If you’re pouring a new slab with the finish, slab thickness will depend on the application.

Ask a concrete driveway company near you which is the best option for your situation.

Concrete can crack from general wear, improper installation, or in response to uneven support from the soil underneath. Small, thin cracks on the surface of aging concrete are often a result of normal wear and tear, while cracks on new concrete likely indicate a problem with installation. Larger cracks or uneven steps can signify a much more severe issue. A concrete contractor should be able to diagnose the cause and repair concrete cracks for you.
