Draining calcareous clay is half the fix
Because Crosby-Brookston clay holds water and swells so predictably, regrading and drain routing around a Carmel house matter as much as the structural repair -- skip that and the same seasonal pressure just rebuilds.
What a full repair scope covers
- Existing conditions and likely cause
- Preparation and protection
- Materials, compatibility, and installation details
- Permits, testing, cleanup, and restoration
- Exclusions, warranty terms, and change-order process
