When a yard slopes or a basement walkout needs to reach grade, a staircase does more than connect two elevations. It retains soil, handles runoff, and carries structural load. We pour engineered staircases with proper footings, reinforcement, and drainage so they perform through Las Vegas winters. Free written estimate.
Why Staircase Construction Differs from Entry Steps
A front entry step is a single rise from threshold to walkway. A staircase spans a grade change, often cutting through a slope that must be held back on both sides. The concrete slab itself becomes a retaining structure, and the drainage plan becomes as important as the pour itself.
Walkout-basement staircases exit the basement door and climb to yard grade, cutting a path through the soil. Yard staircases descend a slope in multiple flights, with landings where code or comfort demands a rest. Both types require engineered drawings that specify rise, run, footing depth, rebar placement, and how water leaves the system.
Rise, run, landing positions, and retaining heights are set by the engineer. We review the drawings with you, confirm top and bottom elevations, and identify any soil conditions that affect the design.
Retain the cut sides
The slope on either side of the staircase is held back with poured concrete walls, block, or a hybrid system. Proper retention prevents the cut from sloughing and keeps the staircase stable.
Form and reinforce flights
Each flight is formed to the engineered rise and run. Rebar is tied throughout, landings are formed, and any handrail embeds or anchor points are set before the pour.
Pour, cure, and drain
The staircase is poured in the sequence the engineer specifies, with proper cure time between flights. Drainage at the low point is tied to the property system or daylighted, and the whole stair is tested with water.
Staircase as structure
Staircase Pours Are Structural, Not Cosmetic
A staircase is a small civil structure. It carries foot traffic, holds back soil, and sheds water. Every aspect, footing depth, rebar size and spacing, landing slope, drainage tie-in, is determined by engineering, not by convention. We work from engineered drawings on every project, and the cost of design is included in the written quote.
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.
Homeowner reviews
What Las Vegas Homeowners Say About Their Staircases
Walkout-basement staircase, two flights with a landing, engineered drawings followed exactly. Drains the way it was designed to, no puddles. Worth the project.

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

★★★★★
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.
