Helical piles in Caseyville, Illinois

Caseyville is in the Metro East area across the river from St. Louis, not far from the sinkhole plain the Illinois State Geological Survey has mapped. It counted more than 10,000 cover-collapse sinkholes in Monroe County alone. For properties in southwestern counties, that mapping is a helpful reference before foundation design begins.

Helical piles can reach competent soil with compact equipment and give a measurable capacity check at each location, and they can go in during winter when frozen ground would delay footings. Central and southern Illinois communities generally use shallower frost depths than Chicago, but each municipality or county sets its own.

Costs and what to ask

HomeGuide reports typical installed prices of roughly $2,000 to $4,000 per pier nationwide. In Illinois, deep frost requirements, urban access, and soft soils can all affect price. Read our helical pier cost guide for what a quote should include.

Questions to put to any installer:

  • Who is the engineer of record near sinkhole-prone ground, and what loads were assumed?
  • What final torque and depth will each pile reach, and will those readings be documented?
  • Is the shaft hot-dip galvanized, and is that enough for wet clay?
  • Does the quote include permit fees from the Village of Caseyville or St. Clair County, and how long does the warranty run in writing?
