A property management company that we do a lot of mowing, landscaping, and snow work for has contacted me about a wall they got wrote up on. I know they don't have alot of money in this properties account and want to fix it as cheap as possible. It appears the wall wall back filled with dirt and not compacted and there is no drain behind it. I am thinking I can take the wall down put a drain tile behind it, backfill with the right stuff and compact the fill, and use geogrid to tie it in with the soil behind it. I think the base might be ok but I won't decide until the wall is down. Do you think the improper construction is causing the wall to lean or is it roots from the tree?
