i will see what the Concrete stabilization company has to say. i can live with the driveway as there is no other issue with it. I'm just tired of the caulk expense every year. Reading you earlier posting on preparation and equalizing the depth to the width, I do not believe has ever been done by any of the contractors hired. One at a bid of 4.5K offers an 8 year warranty. While it's pricey i can guarantee I've probably spent 2x that in the last 8 years.
So i will seer what mr. stabilizer has to say (they are very well known) and then likely quiz mr caulker a bit more with my newly gained knowledge and go from there.
I will be reporting back. thanks again to all for their assistance
