I inspected the driveway 2-weeks after the completion. (I live out of town)
The 14' wide driveway had a crack all the way across the width and down both sides of the slab (4" thick).
This line is directly over a PVC pipe that was placed under the driveway in order to run cables in the future. (General Contractor suggested it for this purpose)
Everything I have read online says that the only reason this would crack all the way across was because the ground was not prepped for the pvc pipe and the pipe was just laid on the ground and the concrete was poured over it.
Does anyone have expertise on their opinion of what could have caused this crack?
The contractor has offered the following repair
1) Grind a "V" trench at the crack approximately 3/4 of an inch wide.
2) Blow out concrete powder and debris.
3) Inject two part epoxy made by Simpson Strong Ties into the v trench/crack. Same material that is used to anchor seismic ties or anchor bolts.
4) Fill the top layer; approximately 1/2 inch with 8000 psi concrete mix. Called Sheplers Patch Plus.
5) Fill the last layer with Eucoreco surface patch.
6) Blend in the panel to color.
I am being told by non-experts in construction, that they believe this is just a band-aid and it will fail in a few years.
Does anyone have any experience with driveway construction, concrete, the products that are proposed to repair the crack ??
any input would greatly be appreciated.
