Engineered Staircase Construction for Detroit Yards

When a slope demands multiple flights, landings, and retaining walls, you need a staircase, not just steps. Detroit Concrete designs and pours multi-flight staircases for yard grade transitions and walkout basement exits, with proper footings, reinforcement, and drainage so the structure lasts through freeze-thaw cycles. Call for a free written estimate.

  • Designed by engineer, not guesswork
  • Retains soil on both sides of cut
  • Drainage tested before handoff

Staircase scope

Why Staircase Construction Differs from Entry Steps

A front entry step connects a door to a walkway in one or two risers. A staircase bridges a significant grade change, often cutting through a slope that must be retained on both sides, and typically includes multiple flights separated by landings. The structural demands are fundamentally different.

When a staircase descends a yard slope, it becomes a small retaining structure, holding back soil on either side of the cut. Walkout-basement staircases rise from the basement door to yard grade, similarly retaining the excavated slope. Both scenarios require engineered footings, proper reinforcement throughout the pour, and a drainage system that prevents meltwater from pooling on the treads or landings.

We coordinate staircase work with any adjacent block retaining walls, the basement waterproofing system, and the overall foundation strategy. Every staircase is poured to engineered drawings.

Build sequence

How We Pour a Staircase in Detroit

  1. Engineer the geometry

    Rise, run, landing placement, and retaining wall heights are designed by engineer. We review the drawings with you, confirm top and bottom elevations, and identify any tie-ins to existing grade or basement structure.

  2. Excavate and retain

    The slope is cut to the engineered profile. Retaining walls (poured concrete or block) are built on proper footings to hold back the soil on either side of the staircase cut.

  3. Form and reinforce

    Each flight is formed to the exact rise and run. Rebar is tied throughout, handrail embeds are set, and landings are formed with a slight slope for drainage. The pour sequence is planned so each flight cures before the next is poured.

  4. Drain and test

    The low point of the staircase is connected to property drainage or daylighted. Landings slope to shed water. The entire system is tested with water to confirm meltwater flows away from the staircase.

Staircase as structure

Concrete Staircases Are Structural, Not Decorative

A staircase is a small civil structure. It carries live load (people and snow), dead load (its own weight), and lateral load (soil pressure from the retained cut). The design must account for all three, which is why every staircase we build starts with engineered drawings.

Pair the staircase with poured concrete retaining walls if the project needs them, coordinate with the basement crack repair or waterproofing if the stairs serve a walkout, and integrate with the broader residential concrete scope.

Common questions

Staircase Construction Questions, Answered

Engineered design, walkout stairs, retaining the cut, drainage and landings.

For anything with multiple flights or any retaining role, yes. The geometry, the loads and the slope all need design rather than rule-of-thumb. We work from the engineer's drawings on every project and the cost of design is in the quote.
Yes; walkout-basement stairs are one of the most common uses for residential staircase construction. The stair runs from the walkout door up to yard grade, retains the cut on either side, and drains away from the door.
Code requires a landing after a certain number of risers, and good design uses landings whenever a flight gets long enough to feel unsafe. We design landings in where they belong rather than forcing one long flight.
Landings are sloped slightly to shed water to one side; the low point of the whole staircase is tied to the property drainage or daylighted. Done right, meltwater leaves the stair instead of running down it.
Several weeks for a typical residential staircase, because engineering, retaining, multiple pours and cure time stack up. The full schedule is in the written quote so you can plan around it.

★★★★★

Walkout-basement staircase, two flights with a landing, engineered drawings followed exactly. Drains the way it was designed to, no puddles. Worth the project.

Z. T.
Detroit
★★★★★

Yard staircase down a steep slope, retained both sides as it descended. Cut through the slope without sloughing once. Real civil work, real quality.

Z. H.

★★★★★

Engineer worked directly with their crew. Communication was tight, the build followed the drawing exactly, and the staircase has held perfectly through three winters.

Y. C.

★★★★★

They were clear that staircases are not just steps; engineered, retained, drained. The quote reflected the scope and the build matched the quote. Honest from end to end.
