Why grading matters in St Louis
In areas with clay-dominant soil, surface water does not absorb quickly. Improper grading allows runoff to accumulate against foundations, increasing hydrostatic pressure and soil expansion.
Correct slope directs water away before it becomes structural stress.
Common grading problems
- Yard sloping toward structure
- Settled soil near foundation
- Water pooling along exterior walls
- Erosion near footings
- Low zones collecting storm runoff
Grading corrections
- Re-sloping soil away from foundation
- Compaction to prevent settling
- Integration with French drains
- Surface water channeling
- Drainage system coordination
When grading should be evaluated
- Recurring water near foundation after storms
- Cracks forming in basement walls
- Soil pulling away from structure
- Standing water in predictable areas
- Sump pump cycling excessively
