Slab Reconstruction of the Underground Parking Garage

Structural Repairs

Our team carried out the repair of several damaged columns and walls. Delaminated concrete was removed, and the reinforcement was assessed, treated, or replaced depending on its condition. Each intervention was validated using precise testing, in coordination with the engineering firm’s plans. Formwork and resurfacing helped restore the full strength of the structures.

Excavation and Backfilling

The plumbing conduits had to be replaced. We began by breaking and removing the existing slab, then excavated the targeted zones. Once this step was completed, our plumbing subcontractor installed the new pipes. We then carefully backfilled and rebuilt each necessary layer up to the base of the slab.

Pouring of the New Slab

To facilitate the concrete pour, openings were made on each upper level of the parking garage. Given the scale of the project, a surface area of 46,300 square feet, the new slab was poured in four distinct sections. This methodical approach ensured a high level of control and precision at every step.

Protective Membrane

Following the slab pour, the final step consisted of applying a thin membrane specially formulated to protect the concrete surface. This membrane, carefully mixed and applied by our team, ensures the durability and waterproofing of the structure, thus extending the slab’s lifespan.

Blocks and Circulation: A Challenge Met

Breaking the slab on the 7th basement level and hauling out concrete blocks in such a confined space was a real challenge. Despite tight conditions and circulation on the other levels of the garage, the entire team did an outstanding job.
