Hi im doing a DIY project which need to build 30cm height retaining wall to hold up some gravels for an above ground pool 5000liter size 2.3x4m And the foundation pad area is 3x4m Im thinking to use steel post to save some space but couldn’t find any specs whether it can stand 12kpa surcharge
I wonder if anyone has this specs or teach me how to calculate if the retaining can stand this load from the above ground pool
Thanks
