In Ontario’s competitive commercial and residential construction sectors, managing trade schedules and specification standards requires reliable subcontractor partnerships. Flooring scopes—including structural slab prep, moisture vapor mitigation, self-leveling underlayments, resinous coatings, and architectural concrete polishing—sit directly on the critical path. A failure in substrate preparation or coating execution disrupts downstream trade handoffs and risks costly project delays.
At AK Level & Polish, we partner with General Contractors, construction managers, and developer-builders across Toronto, the GTA, and Southern Ontario. As a specialized Division 3 (Concrete) and Division 9 (Finishes) subcontractor, we deliver turnkey floor preparation, remediation, and high-performance resinous coating systems built to satisfy strict architectural standards and project delivery timelines.
Key Subcontracting Capabilities & Trade Scopes
Equipped with high-capacity industrial machinery, certified installers, and dedicated site supervisors, we handle comprehensive flooring sub-scopes across various sectors:
1. Mechanical Surface Preparation & Slab Profile (CSP 1–5)
Unbreakable mechanical bonding requires proper substrate preparation. We execute closed-loop, dustless surface preparation across active and enclosed job sites:
- Planetary Diamond Grinding: Multi-head grinding to strip old mastics, carpet adhesives, curing compounds, and surface laitance while creating an even profile for thin-film or high-build systems.
- Enclosed Shot Blasting: Enclosed steel-shot blasting to achieve ICRI Concrete Surface Profiles (CSP) 3 through 5, essential for heavy-duty urethane cement mortars and thick self-leveling overlays.
- Adhesive & Coating Removal: Polycrystalline diamond (PCD) tooling to strip fail-prone tile glues, black mastic, old epoxies, and elastomeric coatings.
2. Hydraulic Self-Leveling Underlayments (SLU) & Slab Remediation
Out-of-level or pitted concrete slabs delay the installation of finish coverings (LVT, hardwood, tile, sheet vinyl) and cause structural inconsistencies. Our continuous mixing pumps handle mass-volume placement:
- Tolerance Correction: Achieving specified FF/FL (Floor Flatness/Floor Levelness) numbers for logistics hubs, retail plazas, and multi-family high-rises.
- Fast-Drying Underlayments: Rapid-setting hydraulic cements allowing foot traffic in 2–4 hours and moisture-sensitive floor covering installation within 16–24 hours.
- Deep Fill Ramping: Ramping transitions and leveling severely compromised slabs from 1/8″ to 3″+ in a single lift.
3. High-Performance Resinous & Epoxy Coating Systems
We supply and install fluid-applied resinous flooring tailored to functional job-site specifications:
- Urethane Cement / Mortar: 3/16″ to 3/8″ heavy-duty thermal-shock systems designed for commercial kitchens, food processing plants, and washdown bays.
- 100% Solids Industrial Epoxy: High-build protective systems for manufacturing facilities, warehousing, auto dealerships, and mechanical rooms.
- Polyaspartic & Rapid-Cure Systems: UV-stable, fast-curing topcoats designed for rapid turnaround in retail spaces, residential garages, and high-traffic corridors.
- Decorative Flake & Metallic Epoxy: Custom aesthetic designs for commercial lobbies, showrooms, locker rooms, and multi-family residential amenities.
4. Architectural Concrete Polishing
For projects specifying low-maintenance, exposed concrete surfaces:
- Multi-stage wet/dry mechanical polishing ranging from honed satin (200–400 grit) to high-gloss mirror finishes (1500–3000 grit).
- Application of penetrating lithium silicate densifiers and stain-resistant protective guards to maximize surface density and abrasion resistance.

Why Contractors Partner with AK Level & Polish
Schedule Control & Capacity
Liquidated damages and milestone dates require zero trade delays. Our crews operate with heavy-duty machinery (high-CFM HEPA dust extractors, planetary grinders, continuous mixing pumps) and offer flexible shift options—including night and weekend work—to protect your critical path.
Specification & Compliance Standards
We support project submittals, architectural specifications, and relevant ASTM standards:
- Sub-Slab Moisture Vapor Mitigation: In-situ Relative Humidity (RH) probe testing (ASTM F2170) and application of 100% solids epoxy moisture mitigation barriers (ASTM F3010) when slab MVER exceeds manufacturer tolerances.
- Silica Control & Site Safety: Full compliance with Ontario Occupational Health and Safety Act (OHSA) regulations, utilizing closed-loop HEPA dust extraction across all preparation and grinding operations.
- Submittal Management: Technical data sheets, Safety Data Sheets (SDS), system mockups, and material certifications provided for fast consultant sign-off.
