6-Step Commercial Concrete Process
- 1. Project Consultation & Permit Coordination
- 2. Site Clearing, Grading & Compaction
- 3. Custom Formwork & Rebar Placement
- 4. High-Strength Concrete Placement & Vibration
- 5. Joint Sawing & Surface Finishing
- 6. Curing, Sealing & Final Inspection
Detailed Commercial Steps
Step 1: Consultation & Engineering
We review your needs—foundation loads, elevator pit dimensions, equipment weights—and coordinate permits and engineered drawings.
Step 2: Site Prep & Subgrade Stabilization
Excavation, compaction, and gravel base installation create a uniform, stable substrate for foundations and slabs.
Step 3: Formwork & Reinforcement
Custom timber or steel forms are erected to tolerance. We install epoxy-coated rebar or fiber-reinforced mesh per engineer specs.
Step 4: Concrete Placement & Finishing
High-strength concrete is pumped, vibrated, and leveled. Power trowels or broom finishes are applied according to use—smooth for elevator pits, broom for parking lots.
Step 5: Joint Sawing & Sealant Application
Control joints are saw-cut at engineered spacing. Polyurethane sealants are installed for durable, watertight joints.
Step 6: Curing & Inspection
Surfaces are cured with compounds or water methods. We perform a final quality inspection and provide maintenance guidelines.
