It was a BAD TIME for this building inspector to show up.
What happens here
Due to the discovery of an inadequate frost footing for the sun porch, the initial plan for a single-tier retaining wall has been modified. In this section, a two-tier retaining wall system will be constructed to provide the necessary frost protection for the existing house foundation. Begin by installing the base course of blocks for the lower tier, ensuring it is perfectly level. Each layer of blocks will then be built upon this base, with geogrid installed at specified intervals behind the blocks to provide reinforcement.
Goal: Build a two-tier retaining wall to ensure frost protection for the house's sun porch foundation.
