Simple Process

How Basement Walkout Works in Oakville

  1. 1

    Site Assessment & Design

    We assess the foundation wall, soil type, grade elevation, and available exterior space. The structural engineer designs the lintel, retaining walls, and drainage layout. Drawings go to the city within the week.

  2. 2

    Excavation

    Crew excavates the stairwell footprint to the target depth, typically 100 to 200mm below your finished basement floor. Soil is removed, the area is shored if required, and the footing is formed and poured.

  3. 3

    Foundation Opening & Lintel

    The foundation wall opening is saw-cut to the door width specified in the drawings. A structural steel lintel is installed above the opening to carry the wall load before any concrete is removed. Retaining walls are formed and poured on both sides of the stairwell.

  4. 4

    Waterproofing & Handover

    New exterior surfaces receive a waterproofing membrane and a perimeter drainage channel that ties into the main drainage system. The rough opening is framed, the stair is poured or formed in steel, and the project is handed over with permit close-out and inspection sign-off.
