Statewide cost drivers here are clay soils and deep frost. Locally, seasonal high water tables can force a raised system. That is why a chamber system in Indiana can land well above or below the national range of $5,000–$11,000.

Chamber systems replace gravel with plastic chambers. They are lighter, faster to install and work well on sites where gravel delivery is expensive.
