Basement Separate Entrances & Walk-Out Doorways in Cochrane
A full-height doorway cut out of a solid poured foundation wall — a separate entrance for a basement suite, or a true walk-out where the lot has the grade for one.
Separate Entrances on Cochrane foundations
Cochrane has the grade. The ground climbs west and sloped sites are common, so a true walk-out is a realistic request here more often than almost anywhere else we serve, and the walls are mostly modern reinforced concrete that cuts predictably. What flips the usual balance is what sits under the grass: dense glacial till with cobbles, and shallow bedrock as you move up the slope. Digging a stairwell or a walk-out approach in that can take longer than cutting the wall does — the opposite of how these jobs normally run.
So in Cochrane we scope the excavation before the concrete, and the retaining afterwards is designed for rocky ground rather than for clean fill. The buyer is usually a family on a sloped lot who wants the lower floor to open onto the yard, and on the right lot that is exactly what the grade delivers; on a flatter one it is still a separate entrance, just a below-grade one. Permits go through the Town of Cochrane, and a structural alteration of this size carries a stamped drawing from an APEGA-licensed P.Eng.
How we run this one
Structural review
A doorway removes far more wall than a window. What sits above it, and how far the load has to travel sideways, is settled before any blade touches concrete.
Shoring and locates
Temporary support goes in where the review calls for it, and Alberta One-Call locates are cleared before excavation.
Excavate the stairwell
The stairwell footprint is dug out to depth so the wall is exposed full height and there is somewhere for the door to open into.
Cut and set the lintel
The opening is wall-sawn to layout, the section removed in pieces, and a sized steel lintel or header set to carry the wall above.
Door, stairs, retaining
Door set and sealed, stairs formed, and the retaining walls and drainage built to hold the excavation open permanently.
Town of Cochrane is the authority having jurisdiction for this work, and we confirm what the wall is actually made of before anything is quoted. No price appears on this page — here is what moves the number , and here is the job in full .
