Location: Colombo, Sri Lanka
Client: Private Commercial Complex Developer
Project Type: Industrial Concrete Polishing with Epoxy Markings
Services Provided: Concrete Polishing, Epoxy Floor Markings, Surface Preparation, Chemical Hardening
Project Background
The client, a leading commercial complex developer in Colombo, commissioned Thewnadee Engineering (Pvt) Ltd to provide durable and aesthetically functional flooring for a multi-level parking garage. The flooring needed to support heavy vehicle traffic, provide clear guidance with epoxy markings, and offer long-term durability with minimal maintenance.
The primary objectives were:
- Durable concrete surfaces capable of withstanding vehicle loads and constant traffic
- Smooth, polished flooring for aesthetic and safety purposes
- Epoxy floor markings for parking guidance, safety zones, and directional flow
- Chemical and abrasion resistance to protect against vehicle fluids, tire marks, and cleaning agents
- Low maintenance, long-lasting surfaces for commercial operations
The project required expert concrete polishing combined with professional epoxy application to meet both operational and visual requirements.
Challenges Faced
Several challenges were identified during the initial site assessment:
- High Vehicle Traffic
- Floors needed to withstand constant vehicular loads, tire friction, and turning forces without surface degradation.
- Complex Multi-Level Layout
- The garage included ramps, corners, and varying elevations, requiring careful planning of polished areas and epoxy markings.
- Safety Requirements
- Clear visual guidance for parking and pedestrian safety was essential, demanding high-visibility epoxy markings.
- Dusting and Surface Durability
- Unpolished concrete is prone to dusting, cracking, and uneven wear, which could compromise safety and maintenance.
- Time and Accessibility Constraints
- The garage was part of a larger commercial complex with tight timelines, requiring efficient execution without impacting other operations.
Engineering Solution
Thewnadee Engineering implemented a comprehensive flooring solution, combining concrete polishing and epoxy floor markings:
Step 1: Surface Preparation
- The concrete substrate was thoroughly cleaned, and any cracks, spalls, or uneven areas were repaired.
- Surface leveling and profiling ensured optimal adhesion and a smooth finish for both polished concrete and epoxy markings.
- Moisture levels were measured and managed to prevent adhesion failure or surface degradation.
Step 2: Concrete Polishing
- Multi-stage grinding using industrial diamond abrasives leveled the surface and exposed fine aggregates.
- Progressive polishing created a smooth, reflective finish, enhancing both aesthetics and functionality.
- Polished concrete increased surface density, reducing dusting and improving wear resistance.
Step 3: Chemical Hardening
- A concrete densifier was applied to harden the surface, reduce dusting, and increase abrasion resistance.
- This treatment enhanced durability under high traffic and vehicular loads.
Step 4: Epoxy Floor Markings
- High-visibility, industrial-grade epoxy coatings were applied for:
- Parking bays and directional arrows
- Safety zones and pedestrian pathways
- Ramp edges and hazard areas
- The epoxy markings were durable, chemical-resistant, and clearly visible, even under vehicle movement and cleaning operations.
Step 5: Anti-Slip & Safety Measures
- Selective anti-slip additives were applied in ramps, corners, and high-traffic pedestrian areas.
- Final inspections verified uniform polish, clear markings, and adherence to safety standards.
Materials and Techniques Used
- Industrial Diamond Abrasives: For multi-stage concrete polishing
- Concrete Densifiers: Chemical hardening for abrasion resistance and durability
- Epoxy Markings: High-visibility, chemical-resistant industrial epoxy
- Surface Profiling Tools: Mechanical grinders and leveling devices
- Anti-Slip Additives: Applied in high-risk areas
- High-Strength Patching Compounds: For repairing cracks and surface defects
