Fixing fower beds on a hillside.
We put 6 x 6 treated lumber on our hillside quite a few years ago. Now it is leaning out and we can't get the bolts or rebar out. What can we do to get this apart and how can we fix this hillside 4 level flower beds so it doesn't lean out again. Do we need to bury the bottom layer of lumber and then work up? The first section has a cement wall with drainage pipe at the bottom, the lumber sections are about 30" high. Thank you, Priscilla
A properly constructed retaining wall should have a base layer completely buried below grade. Each successive layer of material (whether lumber, railroad ties, or landscape blocks) should step back (lean into the slope) by 1/2 to 1 inch or so. It sounds as though your wall had some aspects done correctly, i.e. drainage behind the wall to remove excess water, and a height limitation of 3 feet or less for each wall.
If you don't have the tools to remove the bolts or cut the existing rebar, you may need to call in a professional to do the job.
