In the high-humidity environment of Kuala Lumpur and Selangor, the concrete or metal basin of a cooling tower is under constant hydrostatic pressure. Over time, the combination of turbulent water, chemical treatments, and structural vibration causes micro-cracks and corrosion. A leaking basin doesn't just waste expensive treated water—it can lead to structural rebar corrosion and water ingress into the building's slab.
EKG M&E Sdn Bhd provides industrial-grade waterproofing and protective coating solutions designed to withstand the harsh chemical and thermal cycles of an active HVAC plant.
We don't just "paint" the basin; we engineer a multi-layer barrier.
Waterproofing fails if the bond is weak.
Pressure Washing & Degreasing: We remove all "Bio-film," algae, and scale deposits.
Mechanical Grinding: For concrete basins, we grind the surface to achieve an open-pore profile (CSP 3-5) to ensure the coating "roots" into the substrate.
Crack Injection: Visible cracks are chased out and filled with high-strength Epoxy Resin or polyurethane grout to restore structural integrity.
For severely degraded basins, we recommend an FRP Lining.
The Process: We apply a layer of glass fiber matting saturated with high-grade vinyl ester resin.
The Result: This creates a "tank-within-a-tank" that is 100% seamless, chemical-resistant, and physically strong enough to handle the weight of the water and internal mechanical components.
For standard maintenance, we utilize multi-coat high-build systems.
Chemical Resistance: These coatings are formulated to withstand the oxidizing biocides (Chlorine/Bromine) used for Legionella control.
Thermal Flexibility: The coating must expand and contract with the tower's temperature fluctuations (30°C to 45°C) without cracking or delaminating.
As an HVAC and Clean Air Specialist, we ensure the waterproofing supports the mechanical performance of the tower:
Nozzle & Sump Strainer Protection: During the coating process, we protect all suction outlets and spray nozzles to prevent clogs.
Vibration Isolation: We inspect the motor and fan mountings. If the tower is vibrating excessively, it will crack even the best waterproofing. We can recalibrate your Variable Frequency Drives (VSD/VFD) to ensure smooth "Soft-Starts," reducing the mechanical shock on the basin structure.
Balanced Water Levels: We recalibrate the float valves post-coating to ensure the "Operating Level" is maintained, preventing dry-running of the Condenser Pumps.
| Feature | Standard Bituminous Paint | EKG M&E Industrial Coating |
| Durability | 6–12 Months (Peels). | 5–10+ Years (Seamless). |
| Chemical Resistance | Low (Degrades with Biocides). | High (Vinyl Ester/Epoxy). |
| Leak Prevention | Temporary fix. | Structural Waterproofing. |
| Downtime Impact | Frequent repairs needed. | Long-term reliability. |
Holiday Testing: We use High-Voltage Spark Testers (Holiday Detectors) to find pinholes in the coating that are invisible to the naked eye, ensuring 100% water-tightness before refilling.
MOH Compliance: Our coatings are non-porous, making it significantly easier to scrub away "Bio-sludge" during mandatory Ministry of Health cooling tower cleanings.
Strategic Support: Based in Kuala Lumpur, we provide turnkey basin restoration, mechanical repairs, and scheduled maintenance for commercial and industrial facilities.
