Restoring Underground Garage Parking in Toronto and Greater Toronto Areas
KG Building Restoration Inc. is Toronto’s trusted specialist in the comprehensive restoration of underground parking garages. We deliver durable, code-compliant solutions for high-rise condominiums, commercial properties, and public facilities across the Greater Toronto Area, including Mississauga, Oakville, and Hamilton.
Underground parking structures are constantly exposed to harsh conditions—from corrosive de-icing salts and vehicle fluids to the relentless stress of daily traffic and freeze-thaw cycles. If left unaddressed, minor issues like small leaks or cracks can escalate into significant structural problems, compromising safety, diminishing property value, and leading to costly emergency repairs.
Our team provides expert solutions that not only repair existing damage but also protect your property for the future, ensuring full compliance with the Ontario Building Code.

Common Underground Parking Garage Problems We Solve
- Water Infiltration & Leaking Crack Repair
Active leaks through ceilings, walls, and expansion joints are a primary cause of long-term damage. We identify the source of water intrusion and implement targeted waterproofing solutions.
- Spalling & Delaminating Concrete Restoration
Flaking, chipping, or separating concrete on soffits, columns, and slabs is a clear sign of underlying distress, often caused by corroding rebar. Our expert parking restoration team is experienced in repairing such issues.
- Fixing Exposed or Corroded Reinforcing Steel (Rebar)
Once moisture penetrates the concrete and reaches the rebar, corrosion begins, which expands and breaks the surrounding concrete, severely weakening the structure. We specialize in restoring it.
- Repairing Failing Waterproofing Membranes
The original underground parking waterproofing system can degrade over time, allowing water and chlorides to seep into the concrete slab, accelerating deterioration. Our restoration team specializes in repairing damaged waterproof membranes.
- Restoring Deteriorated Expansion Joints
Damaged or leaking expansion joints do not accommodate structural movement, leading to widespread cracking and water damage. When this happens, KG Building Restoration Inc is available to save the day!
- Fix Damaged Traffic Toppings & Coatings
Worn, cracked, or peeling traffic coatings compromise the first line of defense against water and salt penetration. When this happens, contact us for a prompt and professional parking restoration service.

Our Comprehensive Underground Garage Restoration Process
We believe in a transparent, systematic approach that ensures quality, manages expectations, and minimizes disruption to your residents and operations. Our process is designed to deliver lasting results.
Step 1: In-Depth Structural Assessment & Diagnosis
Step 2: Strategic Demolition & Surface Preparation
Proper surface preparation is critical for a durable repair. Our teams carefully remove all damaged or unsound concrete, clean corroded rebar, and prepare the surface to ensure maximum adhesion of new repair materials and waterproofing systems.
Step 3: Structural Concrete Repair & Reinforcement
We believe in a transparent, systematic approach that ensures quality, manages expectations, and minimizes disruption to your residents and operations. Our process is designed to deliver lasting results.
Step 4: Advanced Waterproofing & Drainage Solutions
Step 5: Protective Coatings, Sealants & Finishing
The final step is to apply a durable, protective finish. This includes applying robust vehicular traffic coatings, sealing all joints and cracks with high-grade polyurethane sealants, and professional line painting to restore a clean, safe, and functional appearance to your garage.
