George,
I've attached my sketch of all the grades we shot yesterday. After studying
this, I don't think grinding is a good option unless you're willing to grind
a very large area, which gets tricky. To get the water from the 9.89 shot
where the water is being held to the gutter at 9.79 (existing water pocket),
you would be removing approximately one tenth of the existing pavement in
places. That's a lot of material to be removed with a grinder. Also, the
finish would be likely be terrible because you'll get into the larger
aggregates which don't grind as well as the "grout" areas.
think replacement might be the only viable option unless you can somehow
pump part of the existing slab as Keith was suggesting.
Please let me know your thoughts.
- Adrian
