Our Detailed, Code-Compliant Concrete Process

1. Comprehensive Site Evaluation & Soil Analysis

We conduct a full property survey; surveying elevations, inspecting existing footings, and collecting geotechnical soil borings. Lab analysis determines soil bearing capacity, groundwater table, and frost-heave risk, guiding our underpinning and foundation repair designs to ensure optimal load transfer and long-term stability.

2. Engineering Plans, Permit Submission & City Coordination

Our in-house professional engineer drafts stamped underpinning and structural drawings. We prepare detailed OBC-compliant permit applications, submit to municipal building departments, and liaise with inspectors to secure work permits swiftly, avoiding delays and ensuring full legal compliance.

3. Precision Excavation & Rebar-Reinforced Footing Installation

Using hydraulic shores and trench boxes, we excavate to engineer-specified depths under controlled conditions. A custom rebar cage is fabricated on-site, then encased in high-strength concrete footings, establishing a stable base for your underpinning, basement extension, or new home addition.

4. Structural Concrete Pouring & Slab Formation

We pour performance-engineered concrete mixes 35 MPa+ with admixtures for freeze-thaw durability; utilizing laser screeds for flatness tolerances. Expansion joints, vibration consolidation, and finishing techniques ensure crack-free, uniform slabs that seamlessly tie into existing foundations.

5. Foundation Crack Injection & Exterior Waterproofing

Any hairline or structural cracks are routed, cleaned, and injected with epoxy or polyurethane resins to restore monolithic integrity. We then apply multi-layer exterior waterproof membranes (Delta MS, Henry Blueskin ) and install weeping tile with socked piping to channel water away from your foundation.

6. Engineered Backfill, Grading & Final Building Inspection

Once concrete achieves design strength, we backfill with free-draining aggregate to promote positive surface drainage. We grade the site to direct water away from the foundation, restore landscaping, and coordinate a final OBC certification inspection; delivering a fully approved, structurally sound outcome.

Types of Foundation & Concrete Projects We Handle

Residential Underpinning
https://www.tornadoconcrete.com/Foundation-Underpinning
  • Engineer-certified underpinning designs that correct uneven soil settlement, including detailed geotechnical report review, structural calculations, and Ontario Building Code compliant stamped drawings.

  • Corrosion-resistant hydraulic helical pier installation, precision-driven into load-bearing strata with minimal site disruption and landscaping protection measures.

  • Laser-guided basement lowering operations: controlled cut-and-remove of interior slabs to increase ceiling height or manage hydrostatic pressure, fully permitted and inspected by municipal authorities.

  • Custom-fabricated rebar cages and 4000, 5000 psi high-strength concrete footings, engineered for long-term stability and resistance to frost-heave and differential movement.

  • End-to-end project management: permit application, city inspection coordination, engineered sign-off, and a 10-year structural warranty backed by comprehensive insurance coverage.

Concrete Additions & Extensions
