Start with conditions, not a product
Pier depth and spacing around Greenville depend on getting below the layer of clay that actively swells and shrinks, which a generic online estimate has no way to account for.
Build a complete scope
- What was measured, and whether it spanned a full wet and dry season
- Whether the house sits on mill-era piers, postwar block, or newer fill
- How water arriving from uphill on a rolling lot is being handled
- The repair proposed, with the alternatives considered and dismissed
- How equipment reaches the work, what is put back after, and written cover
Greenville pier and support context
Because expansive clay behaves differently across even a single Greenville lot, support work here often needs more site-specific engineering than a comparable job on stable ground would.
