Engineered Staircase Construction for Gatineau Slopes
When a yard drops steeply or a basement walkout needs to climb to grade, a staircase does more than connect two levels. It retains soil, handles water runoff, and bears structural load. Gatineau Concrete designs and builds multi-flight staircases to engineered specifications, with proper footings, drainage, and landings where code and comfort demand them.
A front entry step is a single flight from threshold to walkway. A staircase spans a grade change, often cutting through a slope that must be retained on both sides. The concrete slab itself becomes a retaining structure, and the load, drainage, and geometry all demand engineered design before the first form is set.
Walkout-basement staircases rise from the basement door to yard grade, cutting through the foundation wall and the surrounding soil. Yard staircases descend a slope, with retaining walls holding the cut on either side. Both scenarios require footings below frost depth, reinforcement sized to the load, and a drainage system that sheds meltwater away from the stair rather than down it.
Rise, run, landing placement, and retaining heights are set by an engineer. We work from those drawings, not guesses. The engineer also specifies reinforcement and footing depth for the local frost line.
Retain the cut
Poured concrete walls, block, or a hybrid system holds back the soil on either side of the staircase. This is poured and cured before the staircase itself, so the cut stays stable during staircase construction.
Form and pour flights
Each flight is formed to the engineered rise and run. Rebar is tied throughout. Landings are formed. Any handrail embeds or anchor points are set. The staircase is poured in stages with cure time between flights.
Install drainage
Landings slope to a low point. That low point ties to the property drainage system or daylights to daylight. The whole staircase is tested with water to confirm meltwater flows away, not down the treads.
Staircase as structure
Concrete Staircases Are Structural, Not Decorative
A staircase is civil work. It has to carry live load (people, snow), dead load (its own weight), and lateral load (soil pressure from the retained cut). The footings must go below frost depth. The reinforcement must be sized to the loads. The drainage must be designed and tested. None of this is optional or cosmetic.
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 Gatineau 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.

★★★★★
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.
