A reinforced soil retaining wall is a system where a thin retaining wall is anchored into the ground it holds using plastic meshes. The wall surface is typically assembled of small concrete blocks (about 0.3 meters thick and similar length and height) and once every several rows of blocks are assembled ground is being put behind the blocks, leveled and compressed and plastic mesh is being put onto ground and onto blocks exposed horizontal surface, then the same is repeated until the entire wall height is built. The wall is either vertical or very steep.
What happens when the concrete wall wears out? If we disassemble it then the mass of the ground should erode quickly and collapse. How is the wall replaced once it wears out?
