OK long story short....a guy called me to do a small, 3 foot high allen block wall adjacent to his driveway which has inadequate drainage at the bottom. Previously, he hired some jackass who used anchor windsor (the small ones) and that wall promptly toppled. That guy is out of business now and those stones have been removed but what remains is a trench filled with mud and sediment, no base gravel to be found. Normally I would'nt consider a job like this but my truck mechanic (a damn good one) is buddies with him and really wants me to take care of this guy who is his neighbor. This potential customer acknowledges that water will again fill the lower portion of his driveway well and possibly affect the finished wall, should I decide to proceed. He also agrees that I as the contractor, because of these unusual conditions will not be held responsible in case of failure. Now, here's the question: Is it possible to build a good base in this environment? I would like to excavate to dry, undisturbed soil, ram the heck out of it, use geo-tex, compact the gravel properly in 2" lifts, etc., etc. I know how to build a wall properly...I guess I don't have complete confidence in my ability to create a stable base given this set of circumstances. Sure, the customer said he won't hold me accountable, but I know I am accountable anyway, since my truck will be at the site with company name, etc. Any suggestions?
