Mystery of the 'mud-jacked' driveway
Before complete overhaul, consider options
By Paul Bianchina, Friday, May 22, 2009.Q: My cement driveway is about 25 years old and certain spots became "mud-jacked" about nine years ago due to "settling." It is settling again in some areas and I'm wondering whether I should spot fix it again or redo the whole driveway and while at it make sure the foundation (adequate rebar, gravel etc.) is set up right. What's your advice?
A: Whenever I hear about the same problem occurring twice, I'm almost always in favor of doing some additional investigation, and that would be my thoughts in your case as well. It sounds like there might be some groundwater problems, poor compaction or other issues that are going on under the slab, and I'd want to get those looked at before proceeding with another repair.
