New construction still cracks -- here's why
Most Fishers houses were poured within the last thirty to forty years, so a crack here is rarely about an old, tired foundation; it's almost always the Crosby-Brookston clay loam under the slab swelling in wet spells and pulling back in dry ones, working at a joint or corner until it opens.
What belongs in the scope
- Confirming the crack tracks seasonal moisture, not a one-time settling event
- Surface prep and protection around finished landscaping
- Injection or sealant matched to the till-clay movement expected
- Grading checks near the crack, since runoff often feeds the cycle
- Written exclusions and warranty terms before work starts
Why "new" doesn't mean "immune"
Fishers grew from under 400 residents in 1960 to over 93,000 today, so almost every foundation in town was built under modern code -- yet code compliance doesn't cancel out what calcareous glacial till does to a slab edge every wet-to-dry cycle.
