Trigrand completed a comprehensive underground parking garage rehabilitation and landscape restoration project for an occupied residential condominium property in Mississauga. The project involved structural concrete repairs, parking garage waterproofing replacement, podium deck waterproofing, drainage reconstruction, retaining wall construction, interlocking installation, landscaping, and site reinstatement.
The scope of work was designed to restore the long-term performance of the underground parking structure while revitalizing the exterior common areas above the garage deck. Throughout construction, resident access and parking operations remained active, requiring careful planning, phased construction, and ongoing coordination with property management.
Underground Parking Garage Rehabilitation
The underground parking garage rehabilitation included extensive structural concrete repairs and restoration work to address deterioration and extend the service life of the structure.
Key components included:
- Structural concrete repairs
- Concrete restoration
- Parking garage waterproofing replacement
- Suspended slab waterproofing
- Roof slab waterproofing
- Garage deck waterproofing
- Traffic coating installation
- Area drain improvements
- Drainage reconstruction
- Parking line reinstatement
By replacing aging waterproofing systems and restoring deteriorated concrete elements, the rehabilitation improved durability, water protection, and long-term building performance.
Podium Deck Waterproofing & Drainage Improvements
One of the most critical aspects of the project involved the replacement of the existing podium deck waterproofing system.
The podium deck serves as both a common outdoor amenity area and the roof structure above the underground parking garage. As part of the rehabilitation, Trigrand completed waterproofing replacement, drainage upgrades, and grading improvements to improve water management and protect the structure below.
The completed system helps reduce the risk of water infiltration while improving the long-term performance of the parking structure and landscaped areas above
Landscape Rehabilitation & Site Restoration
Following waterproofing and structural work, Trigrand completed a full landscape rehabilitation program to restore and modernize the community’s exterior common areas.
Scope of work included:
- Retaining wall construction
- New planter boxes
- Interlocking stone installation
- Pedestrian walkways
- New stairs and access routes
- Privacy fencing
- Site grading
- Planting and landscaping
- Final site reinstatement
The completed landscape improvements transformed the appearance and functionality of the property while improving resident accessibility and circulation throughout the site.
Working in an Occupied Condominium Environment
Completing a project of this scale within an occupied residential community required careful planning and communication.
Trigrand Restoration team worked closely with property management to maintain safe access for residents while construction progressed through various phases. Advance notices, ongoing updates, temporary access routes, site signage, and traffic management measures helped minimize disruption and maintain safe circulation throughout the duration of the project.
This phased approach allowed major rehabilitation work to proceed while the condominium remained fully operational.
Trigrand’s Self-Perform Advantage
Trigrand self-performed all major scopes of work using experienced in-house crews.
This integrated approach provided greater control over project scheduling, quality assurance, safety management, and coordination between trades. By self-performing structural concrete repairs, waterproofing installation, drainage reconstruction, retaining wall construction, and landscape rehabilitation, Trigrand Restoration maintained continuity throughout all phases of construction and delivered a high-quality final product.
