Concrete has only a few issues that normally trigger a warranty. Cracking, settling and spalling. Cracking and settling are the most common in AZ.

Too much water added to the mix, improper grading or plant mix ratio errors are the main culprits in cracking. Your warranty covers replacement of the cracked section(s) ONLY if a crack opens wide enough to fit a dime into within your warranty period. Fine cracks are cosmetic only and do not qualify for replacement.

Improper compaction leads to settling. If your concrete pour settles it will most likely crack as well. Your warranty will include replacing concrete sections that have settled only if they cause a drainage problem, cracks open up wider than a dime or if it was designed for a structure is to be built on it, making it difficult or impossible to build on.

Spalling or concrete cancer is caused for one main reason in AZ… water splashed onto the surface as a finishing aid. A Flawed mix design may also be the culprit. Unfortunately the spalling doesn’t normally show up until the 2 year warranty is expired. If you received a 5 year warranty any sections affected will be replaced.
