A ‘SuperSupport’ is a component used in the construction of SuperSleeper retaining walls to provide foundational support and stability to the bottom sleeper. It is made from composite materials and serves as the foundation upon which the wall is built. The ‘SuperSupport’ helps to distribute the vertical weight of the retaining wall evenly and prevents settling or shifting of the wall over time. Additionally, ‘SuperSupport’ can be used for providing further stability to the SuperCap when installed atop of top sleeper during retaining wall construction.
