I bought a new construction house in Dec last year.
Most has gone well.
I have discovered a sink hole directly under our poured concrete front porch. There is a small crack in the porch and it appears to me the only think holding up the cement is rebar.
There is a 3" gap under the porch (between porch bottom and grass to one side).
I had a contractor coming to quote me on another job, unrelated. He pointed this out to me on his may into the house.
How would anyone suggest a sink hole like this get fixed? The contractor suggested some "57 gravel" and top soil.
I hope I remembered the gravel term correctly. Please explain or ask questions as needed. thank you.
