Slab-on-Grade, Footings, Piles, and Reinforced Concrete for Commercial Builds
Comprehensive site analysis, including soil testing and geotechnical reports, followed by professional excavation, grading, and compaction to prepare a stable and level base for all foundation elements. This ensures optimal load distribution and mitigates future settlement issues.
Precision engineering and construction of temporary or permanent formwork systems (e.g., wood, steel, insulated concrete forms) for footings, grade beams, foundation walls, and concrete slabs, ensuring accurate dimensions, alignment, and structural integrity of all poured concrete elements.
Expert placement and tying of steel reinforcing bars (rebar) according to engineered structural drawings. This critical step provides tensile strength to the concrete, preventing cracking and enhancing durability, especially in high-stress areas and seismic zones.
Careful selection, delivery, and professional placement of commercial-grade concrete mixes, followed by expert finishing techniques (e.g., troweling, broom finish, power floating) for slabs-on-grade to achieve desired surface characteristics, flatness, and durability for various commercial applications.
Implementation of advanced foundation solutions such as drilled caissons, driven piles, helical piles, or raft foundations, custom-designed to address specific soil conditions, heavy load requirements, or challenging site constraints typical of complex commercial and industrial projects.
Application of high-performance waterproofing membranes, sealants, and installation of perimeter drainage systems (e.g., weeping tile) to protect below-grade foundation elements from moisture intrusion, hydrostatic pressure, and ensure a dry, healthy interior environment for the commercial structure.
Our process begins with a thorough review of structural engineering drawings, geotechnical reports, and site conditions. We collaborate with architects, engineers, and clients to confirm design specifications, identify potential challenges, and develop a comprehensive execution plan that aligns with project goals and Ontario Building Code requirements.
Following approved plans, our team executes precise excavation for footings, foundation walls, and any specialized piling. This is followed by the meticulous installation of formwork, ensuring exact dimensions, plumb, and level. All forms are rigorously braced and inspected to withstand the hydrostatic pressure of the wet concrete.
Steel reinforcing bars (rebar) are accurately placed and tied within the formwork according to engineering specifications. Once rebar inspections are complete and approved by the engineer of record or municipal inspector, high-quality, specified concrete is poured, vibrated to eliminate air voids, and carefully screeded to achieve the required finish and elevation.
After the pour, the concrete undergoes a critical curing period to achieve its designed strength and durability. Our team then performs final finishing (e.g., power troweling for a dense, smooth slab), followed by the application of waterproofing membranes and installation of drainage systems to protect the completed foundation from moisture.
| Scope/Type | Low Estimate | Mid-Range | Premium |
|---|---|---|---|
| Standard Slab-on-Grade (per sq ft) | $15 CAD | $25 CAD | $40+ CAD |
| Standard Strip Footings (per linear ft) | $90 CAD | $160 CAD | $250+ CAD |
| Drilled Concrete Caissons (per linear ft) | $180 CAD | $300 CAD | $500+ CAD |
| Reinforced Concrete Foundation Walls (per sq ft) | $35 CAD | $60 CAD | $90+ CAD |
| Complex Industrial Foundations (per project) | $150,000 CAD | $500,000 CAD | $2,000,000+ CAD |
Please note that these are estimated ranges for commercial concrete and foundation work in Ontario for 2025 and can vary significantly. Key cost drivers include the project's complexity, specific geotechnical conditions (e.g., rock excavation, high water table requiring dewatering), the depth and type of foundation required, concrete strength and specialized additives, rebar tonnage, site accessibility, and the overall project schedule. Union labour rates in certain regions, municipal permit fees, and the involvement of specialized engineering further influence the final pricing. For an accurate quote, a detailed site assessment and review of engineering drawings are essential.
The most common foundation types are: spread footings with slab-on-grade (most commercial buildings), helical or driven piles (poor soil conditions), grade beams, and reinforced concrete walls. Geotechnical reports determine the appropriate system.
Commercial floor slabs in Ontario typically specify 32 MPa (4,600 PSI) to 55 MPa concrete with fibre reinforcement or rebar, depending on live load requirements. Industrial warehouse floors often require flatness tolerances to F-number specifications.
