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.
I 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
