What happens here
With the site graded, proceed to build the retaining walls that will define the different levels of your outdoor space and help manage the slope down to the lake. As seen in the video, these walls appear to be constructed from interlocking concrete blocks. First, dig a stable trench for the wall's foundation, typically filled with compacted gravel. Lay the first course of blocks ensuring it's perfectly level. Subsequent courses are laid, often staggered for strength, and backfilled with gravel for drainage and stability. Consider incorporating geogrid reinforcement for taller walls or those under significant pressure. A concrete saw may be required to cut blocks for corners or end pieces.
Goal: Build the multi-tiered retaining walls and integrated steps.
