For commercial General Contractors (GCs) across Toronto and the Greater Toronto Area (GTA), managing sub-trades requires precise execution, strict schedule adherence, and flawless technical compliance. Flooring scopes—spanning structural slab preparation, self-leveling underlayments, resinous coatings, and concrete polishing—are frequently on the critical path. A delay or failure in substrate preparation cascades down the schedule, impacting every interior finishing trade that follows.
At AK Level & Polish, we partner directly with GCs, construction managers, and design-builders as a trusted single-source flooring subcontractor. We deliver turnkey concrete floor preparation, leveling, and high-performance resinous coating systems engineered to meet demanding architectural specifications and rigid project timelines.
Core Subcontracting Capabilities & Trade Scopes
We handle complete divisional scopes (Division 3 Concrete & Division 9 Finishes) with specialized equipment, certified installers, and dedicated site management.
1. Mechanical Concrete Surface Preparation (CSP 1–5)
A flooring system is only as reliable as its bond to the underlying slab. We execute dustless surface preparation in active or enclosed job sites:
- Planetary Diamond Grinding: Heavy-duty, multi-head grinding to remove existing adhesives, carpet mastic, curing compounds, and surface laitance while creating an ideal profile for thin-film or high-build coatings.
- Shot Blasting: Enclosed steel-shot blasting to achieve ICRI Concrete Surface Profiles (CSP) 3 to 5 for heavy-duty urethane mortars and self-leveling underlayments.
- Glue & Coating Removal: Complete stripping of fail-prone tile glues, black mastic, old epoxies, and elastomeric membranes using aggressive PCD (polycrystalline diamond) tooling.
2. Self-Leveling Underlayment (SLU) & Deep Fill Concrete Toppings
Irregular, out-of-level, or pitted concrete slabs delay floor covering installations (LVT, hardwood, tile) and compromise structural integrity. Our high-flow hydraulic cement pumps handle mass-volume leveling:
- Laser-Guided Leveling: Achieving strictFF/FL (Floor Flatness/Floor Levelness) numbers for warehouse logistics, retail spaces, and high-rise developments.
- Fast-Setting Cements: Rapid-drying underlayments allowing foot traffic in 2–4 hours and moisture-sensitive floor covering installation in 16–24 hours.
- Deep Fill Applications: Restoring severely degraded slabs or ramping transitions from 1/8″ up to 3″+ in a single lift.
3. High-Performance Resinous & Epoxy Coating Systems
We specify and install fluid-applied resinous flooring tailored to functional job-site specifications:
- Urethane Mortar / Cement: 3/16″ to 3/8″ heavy-duty thermal shock systems for commercial kitchens, food processing plants, and washdown bays.
- 100% Solids Industrial Epoxy: High-build protective systems for manufacturing plants, warehouses, auto dealerships, and mechanical rooms.
- Polyaspartic & Fast-Cure Coatings: UV-stable, rapid-curing topcoats designed for fast turnaround in retail and high-traffic corridors.
- Decorative Flake & Metallic Epoxy: Custom aesthetic designs for commercial lobbies, showrooms, locker rooms, and multi-family residential amenities.
4. Architectural Polished Concrete
For projects specifying sustainable, high-durability exposed concrete:
- Multi-stage wet/dry diamond polishing from 200-grit honed to 3000-grit high-gloss finishes.
- Application of lithium silicate densifiers and stain-resistant penetrating guards for long-term abrasion resistance.
Key Operational Trade Comparison
| Subcontracted Scope | Primary Equipment / Technology | Turnaround / Cure Window | Key Architectural Trade Interface |
| Self-Leveling Underlayment | Continuous mixing pumps, laser levellers | 2–4 hrs (foot traffic), 24 hrs (flooring) | Division 9 Tile, LVT, Carpet installers |
| Urethane Cement Mortar | Screed boxes, power trowels | 6–12 hrs (full cure) | Division 22 Plumbing (Drains) & Food Service |
| 100% Solids Epoxy Coatings | Airless sprayers, notched squeegees | 12–24 hrs | Division 21 Fire Suppression & Logistics |
| Polished Concrete | Heavy planetary grinders, HEPA vacuums | Immediate return-to-service | Architectural interior finishes |
Why General Contractors Partner with AK Level & Polish
Schedule Integrity & Capacity
We understand that liquidated damages and milestone dates leave zero room for sub-trade delays. Our crews are equipped with industrial-grade machinery (high-CFM HEPA dust extractors, heavy planetary grinders, continuous-mix pumps) and are capable of double-shift or overnight execution to maintain your project schedule.
Technical & Specification Compliance
Our team works directly with project submittals, architectural specifications, and ASTM standards:
- Sub-Slab Moisture Vapor Mitigation: In-situ Relative Humidity (RH) probe testing (ASTM F2170) and application of 100% solids epoxy moisture barriers (ASTM F3010) when slab MVER exceeds manufacturer tolerances.
- Safety & Site Cleanliness: Fully compliant with Ontario Occupational Health and Safety Act (OHSA) standards, including strict silica dust containment controls (HEPA filtration).
- Comprehensive Submittals: Complete product data sheets, Safety Data Sheets (SDS), technical specifications, and color samples delivered promptly for architect approval.
