I. Introduction: The Vital Importance of Proper Technical Waterproofing In Vietnam's harsh climate, metal roofs are the first line of defense but also the most vulnerable. Constant thermal expansion, oxidation, and joint failures frequently lead to leaks that damage machinery, equipment, and inventory below. We don't just offer temporary repairs; we provide a comprehensive protection system strictly adhering to ISO standards to ensure long-term structural integrity.
II. Analysis of Common Causes for Metal Roof Leakage
Electrochemical Corrosion: Severe rusting at nail holes and screw positions due to oxidation.
Joint Failures: Gaps forming between overlapping metal sheets or at the flashing where the roof meets the wall.
Mechanical Impact: Deformations caused by improper installation or external impacts from debris and environmental factors.
III. Professional ISO-Standard Metal Roof Waterproofing Process
Step 1: Survey, Assessment, and Planning This is the most critical phase. Our engineering team uses specialized equipment to measure roof pitch, inspect the aging level of the metal, and pinpoint every leak source with absolute precision.
Step 2: Surface Preparation and Rust Treatment We utilize hand grinders and wire brushes to treat all rusted areas. High-pressure washers are then used to remove moss, dirt, and debris. Note: The surface must be completely dry before applying the primer.
Step 3: Reinforcement of Critical Vulnerability Points Old, rusted screws are replaced with specialized stainless steel screws equipped with EPDM rubber washers for superior sealing. Fiberglass mesh is applied to reinforce all joints and overlapping seams.
Step 4: Application of Multi-functional Waterproofing Membrane
Primer Layer: Enhances the bonding strength between the metal surface and the waterproofing material.
Main Coating: Application of premium materials such as Polyurethane (PU) or Modified Bitumen, featuring high elasticity (>300%) to withstand thermal movement.
Step 5: Water Pressure Testing and Handover A 24-hour flood test is conducted to ensure 100% leak-proof results. Finally, a periodic maintenance schedule and documentation are handed over to the client.
IV. Why Choose Our Professional Services?
Exclusive Materials: We utilize integrated heat-reflective and waterproofing coatings that can reduce roof temperatures by up to 10°C.
ISO Certification: Every step of the construction is monitored under a rigorous quality management system.
Warranty Commitment: Long-term warranties ranging from 5 to 15 years, depending on the service package.
