Concrete stairs
Stairs carry more load per square foot than the rest of our flatwork, so they start below grade. We dig footings under the bottom riser, run rebar through the risers and into the landing, and pour over a compacted base. Riser height gets held consistent, because a quarter inch of variation is what people trip on. Steps fail at the base almost every time: undersized footing, no reinforcement, backfill nobody compacted. The same detailing goes into commercial concrete entries, where the traffic is heavier.
