We have an old driveway (28' x 8"7") that has sunk towards the house at
least 6 inches. The driveway had 10 mil re-bar drilled into the house but
has since then has just pulled out (or bent or broken off) as the driveway
We want to remove the driveway and replace it with new concrete.
1) Should we use concrete piles (3 to 4) or should we use thicker re-bar
dowelling (3/4") "epoxied" into holes drilled into the foundation?
2) Should I have the base (1' or so) under the present driveway removed and
replaced with a more stable base?
3) What type of base should be used?
4) Any ideas/comments/advice?
