RE: Landscape Retaining Wall

Or just corrugated plastic roofing.  You could even just skip the concrete all together and just shove it down into the dirt 3 or 4 feet like a sheet pile wall.


Please tell me you’re not planning on doing any overturning calculations on this thing J

How about tinted plexiglass? It could be cast into a footing. Add an anodized aluminum channel along the top to protect it from chipping. I'm thinking guardrail type stuff.

Fellow engineers,


        I have a piddly little retaining wall about 12' long retaining up to 2' of soil.  For landscaping reasons it is desirable to have this as thin as possible.  One possible design is an L shaped bent steel plate about 3' high with a 2'  "footing" under the high side utilizing the weight of soil for stability.


        My only concern about this design is corrosion.  I have some thoughts on this. First is to use a low alloy steel which will perform well on the "air" side but I don't know about the "soil" side (I believe A242 might be such a steel).  Second is to provide a corrosion allowance and not worry about it.  Third is to use a protective coating such as asphalt foundation spray.  Fourth is to give up on the whole idea; tell my wife she can't have it (tactfully, of course); and look for a completely different solution.


        Does anyone have any thoughts on this?


Thanks in advance,


H. Daryl Richardson
