Start with conditions, not a product
Pier depth near Gainesville can vary lot to lot more than homeowners expect, since the karst limestone under the sand doesn't sit at a consistent depth and is shot through with old sinkholes and spring channels -- get that wrong and a support system underperforms.
Build a complete scope
- What was measured and whether the slab or the ground beneath is moving
- Whether limestone geology and sinkhole potential were assessed for the parcel
- Whether a leak under the slab is washing material out from below it
- The repair method chosen and what was weighed against it
- Permits, access through finished space, restoration, and warranty terms
Gainesville context
Pier and support choices around Gainesville depend partly on housing type -- historic in-town homes, university-area rentals, mid-century ranches, wooded-subdivision houses, and rural-edge properties. Heavy rain, humid summers, mature tree roots, karst geology, and variable soils affect all of them, just differently.
