These walls can be constructed with either steel UC or UB columns. Often used as temporary retaining for safe shoring of vertical cuts, or when used as a permanent retaining wall, the steel can be painted with an epoxy or galvanized. While often utilising round poles as whalers, they can also have standard flat boards or even concrete panels fitted between the steel.
These can be constructed on boundary lines with minimal intrusion onto the property, and can be constructed as the site is excavated ensuring a safe means of site preparation.
Steel retaining walls can be constructed from top down, or by battering back depending on the site requirements.
