Steps are small pours that take outsized abuse: frost heave from below, salt and ice from above, and point loads on every tread. Keeping them level for decades comes down to a few details.
Frost lifts what it can grab
When water in the ground freezes, it expands and lifts whatever's above it — and a light structure like a set of steps is easy to lift. If the steps bear on shallow, wet, poorly drained soil, frost jacks them up a little every winter, and they rarely settle back exactly where they were. A few cycles later the bottom step is tilted and the rise heights are all wrong.
The defenses are bearing depth and drainage: found the steps on compacted material that drains, so there's less water under them to freeze in the first place.
One piece, not a stack
Steps built as separate dry-stacked pieces — or poured without steel — move independently, and every joint between them opens up. We pour steps with rebar tied through treads, risers, and landing so the whole assembly acts as a single unit. If the ground moves slightly, the steps move as one piece and stay level relative to each other.
The finish matters too: broomed treads with a slight forward pitch so water runs off instead of pooling and freezing where you step.
Salt is the other winter
Deicing salt doesn't heave steps, but it eats their surface — scaling is the flaky damage you see on older steps. A proper mix with the right air entrainment, adequate cure time before the first winter, and a sealer once cured all slow that down. And going easy on the salt the first winter is one of the few things the owner controls.
