Start with conditions, not a product
Pier spacing and depth around Jacksonville depend on how deep the sandy load-bearing layer sits below the seasonal water table, a detail a generic online estimate has no way to account for.
Build a complete scope
- What was measured and whether groundwater at this elevation is a factor
- Whether sandy soil has been carried out from beneath a footing or slab
- Whether past storm flooding on the parcel bears on the diagnosis
- The repair proposed and what was ruled out before selecting it
- Access, restoration of finishes and grade, and the warranty in writing
Jacksonville pier and support context
Because the water table near the New River can sit close to the surface for weeks at a time, support work here often needs a different depth and spacing plan than the same job would need on drier, inland ground.
