Pier depth depends on the till, not the neighborhood's age
Helical or push piers on a Fishers lot generally need to reach past the shrink-swell zone in the calcareous glacial till to a more stable bearing layer, and a proposal should say plainly how deep that is expected to be.
What a solid pier proposal spells out
- Target bearing depth and soil layer
- Helical versus push-pier reasoning for this lot's till profile
- Access plan for newer subdivisions with tighter side yards
- Load-test results recorded at installation
- How existing cracks will be tracked after the piers are set
What changes near the White River
Lots closer to the White River corridor can carry more moisture in the till at depth, which sometimes affects how a crew sequences pier installation compared with drier ground further from the water.
