CORTEN as a planter wall

[Nanda]

anybody has experience with using CORTEN walls. There seems to be a few issues that need to be dealt with.
1) Do you have a structural engg determine the thickness of the plate.
2) what kind of footing do you use. and how is the plate attached to the footing. (detail images would be helpful)
3) how do you deal with corten staining adjacent conc.
4) what kind of welding is best at corners to prevent corrosion and leakage.
any other issues that we need to be aware of ???

anybody used this (see link below) as an alternative to OCRTEN yet. seems to be a good way to deal with the staining issue.

1) depends upon the height you will be making. 8mm is fine for a 50cm seat wall.
2) continuous reinforced concrete footing to frost level. weld rebar to plate to extend deeply into foundation. plate should be embedded into concrete. good drainage must happen behind (gravel, geotex + drainage pipe)
3) ???
4) good welding. where you weld on the back, you will have discoloring on front.

Thx Craig, that’s very helpful, especially the welded rebar idea.
3) When you locate a corten wall next to conc. paving, supposedly the water (irrigation/rainfall) that hits the corten and drains onto the conc paving stains it. Although i haven’t seen this yet, I’ve heard anecdotes… We have detailed a 3″ groove filled with pebbles between the conc. paving and the corten, if that makes sense
