Abbotsford Concrete Staircase Built for Grade and Load
When a yard drops two metres or a walkout basement needs an exit, you need more than steps. Abbotsford Concrete engineers multi-flight staircases to the slope, retains the cut on both sides, and drains every landing before handing over the keys.
Planning an Abbotsford Concrete Staircase: What the Site Tells Us
The first thing we look at on a staircase site is the total grade change, because that number drives everything else: how many flights are needed, where landings have to fall, how much soil the concrete structure has to retain on either side of the cut, and where the low-point drainage has to go. A two-metre drop through a sloped Abbotsford backyard is a very different project from a half-metre front-entry step, even if both involve concrete and risers.
Walkout-basement staircases add another layer. The slab at the bottom of the stair has to sit at finished-floor elevation, the top landing has to meet yard grade, and the concrete on both sides of the cut has to hold the soil back through freeze-thaw cycles without cracking or shifting. That means proper footings below frost depth, rebar tied to the engineer's schedule, and a drainage path that moves meltwater away from the basement door rather than toward it.
We size the project at the estimate stage, so you know before any concrete is ordered whether the scope includes a poured retaining wall alongside the stair, a block wall, or just the staircase itself. See our poured concrete retaining walls and block retaining walls pages for how those tie in. For the full picture of what we build at grade, the sidewalks and walkways page and the foundation installation page show adjacent scopes.

How it works
From Grade Survey to Finished Concrete Staircase
Survey the grade and set elevations
We measure the full grade change, mark the top and bottom tie-in elevations, and confirm the number of flights and landing positions with the engineer before any forming begins. Nothing gets ordered until the geometry is locked.
Excavate and retain the cut
The slope on each side of the staircase corridor is cut back and retained, using poured concrete walls, block, or a combination specified in the engineered drawings. Footings go below frost depth so the retained soil stays put through winter.
Form, reinforce, and pour each flight
Forms are set to the exact rise and run from the drawings. Rebar is tied throughout, handrail post sleeves are placed before the pour, and each flight is cast in the sequence the engineer specifies, with adequate cure time between pours.
Finish landings and connect drainage
Landing surfaces are finished with a slight cross-slope so water sheds to the low side. The drainage outlet at the base of the staircase is tied into the property's drainage system or daylighted, then tested with water before the site is handed back.

Why Staircase Construction Starts with Drawings, Not Concrete
Ordering concrete before the engineering is done on a multi-flight staircase is how projects end up with the wrong riser height, a landing that pools water, or a footing that heaves in the first hard frost. Every staircase Abbotsford Concrete builds starts with a set of engineered drawings that specify the rise, run, footing depth, rebar schedule, and drainage outlet location. The concrete mix and pour sequence follow from those drawings, not from habit.
Drainage is the detail that separates a staircase that lasts from one that deteriorates in five years. When meltwater has nowhere to go, it sits on the concrete, works into any crack, freezes, and widens the crack. Landings pitched correctly and a properly sized outlet at the base of the stair keep water moving off the structure rather than through it. That detail is in the drawings and confirmed in the field before the forms come off.
If your project also involves a walkout basement, the staircase and the basement slab elevation have to be coordinated from the start. For properties where the staircase connects to a wider outdoor concrete area, our pool deck and outdoor living work and stamped concrete patio options can tie in at the top landing. Questions about cost and timeline are covered in our concrete cost guide.
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.

What Abbotsford 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.

Abbotsford
★★★★★
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.
Chilliwack
★★★★★
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.
Mission
★★★★★
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.
