If I'm reading this right, the driveway is splitting longitudinally at the center saw cut joint? Driveway is only 10' wide? And getting wider? Or is it an expansion joint? How wide is the gap now? Expansion joints normally are cut across the narrow portion, not the longitudinal direction. Hindsight being what it is, post tension (VERY unusual if not never for a driveway) is how it should have been done.
1st question, Yes
2nd question, yes
3rd question, in areas an inch or so others hasn't moved at all ( keep in mind it's 600+ ft long)
Hindsight? I would've used a different contractor or at least required wire fence or rebar
I keep thinking of a LARGE HYDRAULIC C CLAMP , or maybe 12ft long 1" diameter all thread
LOL
And the tensioning idea is great but a bit too late
