This is exactly where structural engineers play a critical role before foundation or structural repairs begin. They don’t just look at cracks, they study how the weight of your home is being carried by the foundation and soil.
How Engineers Assess Load Distribution
1. Visual Inspection & Symptom Mapping
- Engineers walk through the property, noting cracks, sloping floors, gaps at doors/windows.
- These symptoms are mapped to see which areas are sinking or carrying excess stress.
2. Elevation Survey (Digital or Manual Leveling)
- They take precise floor elevation readings across the house.
- This creates a “contour map” showing how much one part of the foundation has moved compared to others.
- Helps identify differential settlement patterns.
3. Soil Testing & Geotechnical Reports
- In expansive clay regions (like Houston), soil borings may be taken.
- Engineers analyze how soil type, moisture, and depth affect load-bearing capacity.
- This determines whether steel piers, helical piers, or concrete piers are most effective.
4. Structural Load Calculations
- Engineers calculate how much load walls, beams, and slabs are transferring to the foundation.
- They assess whether the existing foundation can carry that load, or if redistribution via piers is needed.
5. Plumbing & Drainage Checks
- Leaking pipes or poor drainage can soften soil under certain load points.
- Engineers verify whether soil moisture imbalance is the real cause before prescribing repair.
6. Recommendation of Repair Method
- If the load is uneven due to soil failure → piers are added to transfer weight deeper.
- If loads are minor but voids exist → slabjacking/polyjacking might be enough.
- If only cosmetic → monitoring may be recommended instead of immediate structural repair.
✅ In short: Engineers use a combination of elevation mapping, soil analysis, and load calculations to understand exactly where and why stress is uneven. Only then do they design a custom repair plan so your home sits evenly and safely on stable soil.
