I have a retaining wall. It is 36 feet long, and 16 inches high at the one end. The other end is basically level with the ground. I wanted to see if you guys could give me a rough estimate of what it will cost. If you look at the pic to the right you can see the retaining wall has slightly overlapped the garage door, so the wall has failed. It has moved about 1/4 inch since January.  |

All stone? Drystack or mortared? Block with stone veneer? Is there a footing? Do you care if the asphalt has to be cut away? How about patching it? How deep does the wall go below grade?
It's not horrific, but it's a delicate operation in a tight space if you're looking at minimal disturbance of the surrounding work. And labor prices vary widely across the country. My advice would be to find a stone mason (friends' references, or recommendations from masonry supply houses) locally and have him give you an estimate. |
here is a second pic, with a closeup. I can't really answer your questions as for how far below grade it goes etc. I'm not sure. I'm not worried about them ripping up the landscaping (I neglected it since I know it will likely be ripped up), and the retaining wall is not holding up the sunroom, which is behind it.  In that pic it doesn't look like its leaning as much as it is. I should get a pic with a level or straight edge to show how much its leaning. |

Dig it out, add mortar, kick it back in place and see if it holds. (I am not a mason just for the record  )

Done properly for our climate, the base of that wall should have 6-9 inches of compacted 2a modified stone, wall built on top of that base, whether dry stack,/mortared/or retaining wall block, then backfill the wall with clean 2b stone for water drainage. I suspect you got a leak from the roof there draining down in that corner of the bed or the drain pipe leaks there a little. Consider using pvc pipe and glueing that bottom part of the pipe together solid, maybe incorporate into the wall so it exists through the wall, but make sure the grade of the black top drains the water away efficiently.

As far as cost, you're on your own, but I could tear that entire wall out, put in new base, build wall, backfill properly, all in a day easy. Fix the water issues first or have a plan for it before starting the project. |
