Purdue Extension describes Crosby as somewhat poorly drained over slowly permeable till and Brookston as poorly drained, sitting in depressions3. That's why base depth and drainage come up in every Hamilton County quote.

Indiana's residential code lists a 30-inch frost depth for Hamilton County, which applies to footings for pergolas, seat walls, fireplaces and outdoor kitchens2.

Frequently asked questions

Do you serve Cicero and Sheridan?

Yes. We take requests from anywhere in Hamilton County and pass them to an independent local contractor who serves that area. Confirm permit requirements with your town hall.

Why do Hamilton County patios need a deep base?

Most of the county is Crosby and Brookston soil, which drain slowly. Saturated clay that freezes heaves pavers, so a deep, compacted gravel base and good drainage matter.

Do I need HOA approval?

If your neighborhood has an HOA with architectural review, usually yes. Our Carmel and Westfield guides cover typical review timelines.
