I'm working with a guy on a almost similar project.
This guy has a 2 tier rail road tie wall holding up his driveway. Total wall height is 6 ft. The rr tie tiers are about 20in apart.
This guy has a pavement driveway that is only 4 years old. I am going to have to rip 50% of it up to put in the 8ft grid. The best part is the driveway is only 20 feet long. I have to excavate the dirt and have it trucked out, and then truck new dirt in as i build the wall. Since there is no room to stack it.
The next proablem, is this guys driveway is 20 ft long. I know you can't put the gaurd rail right next to the wall, i been hearing engineers like the guard rail 5 feet on the wall on a geo grid wall.
The best proablem is, the first teir of the rail road tie wall was build partially on top of the guys 500 gallon waste water septic tank! I have know doubt, this guy will have to have this tank removed to build any type of wall!
But this guy still has landscapers telling him that he 'don't need no engineering!"
