Michigan Climate & Code Notes
Severe winter frost heave (42-inch depth) and lake-effect moisture require deep crushed-stone footings and vapor barriers.
Pro Field Notes
- Hydrostatic water pressure is the primary cause of wall failure; always install a 4-inch perforated drain pipe wrapped in geotextile fabric.
- Bury at least 1 inch of the bottom block course for every 8 inches of total wall height (minimum 6-inch buried base course).
- Walls over 4 feet high typically require biaxial geogrid soil reinforcement and municipal permits.
