What happens here
At the third job site, the landscaper examines a failing timber retaining wall located underneath a four-season porch. Previous landscapers were deterred by the complex repair. The current plan is to remove the existing wall and regrade the area. He explains that a new retaining wall is necessary here because the soil will exert pressure on the porch's footings. He also specifies using 3/4 inch angular limestone as backfill, rather than Class 5 gravel, because it prevents voids and settlement issues due to its angularity and lack of fine particles, ensuring long-term stability.
Goal: Replace a failing retaining wall with a stable, engineered solution to protect a four-season porch foundation.
