After a year a few cracks appeared on the driveway and also stones started to be missing from the surface after winter. All this should be covered with warranty. I was promised repairs in fall 2018, however, the season ended early, so they moved me to spring 2019. Now it's September 2019 and they never came back. They no longer respond to emails or return the calls
Edit: the repairs finally took place in October 2019. They also put a new layer of finish to protect the stones from falling out from the surface, which were quite noticeable after 3-4 years of having the driveway. Now the driveway looks much better.
