Underpinning section: new footings below the existing block walls
The project
The owners of an existing Toronto home wanted to lower the basement and add a separate walkout entrance, setting the space up as a legal basement unit. The work went beneath the existing cinder block foundation walls, with neighbouring properties close on both sides.
What KMG did
Designed underpinning of the existing foundation walls, with new footings and non-shrink grout
Designed the new basement slab, gravel base and drainage, with weeping tile reset to the lowered footings
Designed a reinforced concrete walkout stair with footings below frost, guards and handrails
Included egress windows and fire separations in the full drawing set for the legal basement unit
Prepared sealed drawings for the City of Toronto building permit
The result
The owners received a complete, permit-ready drawing set for a taller basement with its own entrance, ready to become a legal second unit.
