Hate to start off on a new forum with an off the wall question, but i'd prefer to talk with you fellas that do this all day befoe i pull the trigger. and for the record i've used the search button and have'nt found what i'm looking for situation: MY backyard, this summer i took out 14 tandem loads of dirt, it used to slope from about midpoint in the yard up to the neighbors in my backyard...shot it with the transit and the highest point is 4' taller than grade near the house. When i dug out the yard i kept the back yard higher so finalized grade will be higher and i can run the water out of the yard. But i have to hold this dirt back obviously to prevent further erroding so i'm entertaining all options and that's where you guys come in. Solutions: Spendiest to cheapest- Dig trench footings all the way across the back yard and stick rebar vertical and have it rise above so when we pour above grade it'll all be tied together, along with horizontal rebar to tie it all together too. Am considering building plywood forms since we could do it all in house cheaper than renting aluminum forms. So in doing the wall this way, with proper waterproofing on the back side and tile i would also dig and form the walls for the big stick built shop i'm going to put back there...so it's kind of an all in one deal. or Was thinking of stabbing 6x6's vertically 4' o.c. throughout the layout. Was going to put 5' in the ground and 4' above grade then use 2x6 T&G treated lumber to cover the back side of the wall that will get membraned and backfilled. I was going to implement deadmen into the mix as well to help spread the load behind the wall into the small piece of relestate behind the wall. Install the same waterproofing membrane to the dirt side of the hill, bury tile and back fill with gravel, get it within 2" of finish grade and finish it all over completely around the back of the wall with river rock/decorative rock since i dont want to mess with mowing/weeding behidn the new shop. If i do the wood wall i'd just swap shop construction over to post frame style/pole building style since i'd have my cheap retaining wall and would'nt have to worry about the building itself being implemented as a retainging wall. But i've noticed with the wooden retaining walls i've been seeing, everybody is laying the timbers like bricks. and implementing deadmen to those too. I'd love to go the cement route, but i'm also doing this all out of pocket since business is slower and bank is being tight. so i could move forward faster being cheap, but at the same time i talk myself out of it since i know cheap never gets anybody far cept spending the money all over again later...but if i could build a wood reataining wall that i could get 20-30yrs out of, i'd be happy since i'll prolly be dead by the time that fails. Heck, my mother owned this house for 23 years and the year they built they just stacked landscaping timbers with rerod to terrace the yard off and it was still holding until i dug it all out this summer This is what i'm dealing with and it'll have a building spanning most of the width of the backyard too. thanks and take it easy on the new guy been lurking for awhile, just never joined since landscaping is'nt my bag.
