Noel Pabelonio (Project Engineer) Product Solution Buildrite Rust Converter / Buildrite Epoxy Primer / Buildrite Confix HV / Buildrite Concrete Patch V Project Reference Project Case Study: Residential Concrete Cancer and Spalling Remediation Location / Project Site: 2-Storey Residential House, Batasan Hills, Quezon City Scope of Work: Overhead Structural Repair, Reinforcement Corrosion Treatment, and Vertical/Overhead Mortar Infilling Client: Engr. Noel Pabelonio (Project Engineer) Product Solution (Product Used): Rust Converter, Epoxy Primer, Confix HV, Concrete Patch V Narrative of the Story: During the renovation of an old residence in Batasan Hills, Quezon City, the construction team uncovered a severe case of "concrete cancer" on the ceiling. Years of persistent water leaks from the roof deck had caused the internal steel reinforcements to rust and expand, forcing the surrounding concrete to crack and fall away—a dangerous condition known as spalling. To save the structure, Engr. Noel Pabelonio implemented a comprehensive structural repair system. This wasn't a simple "patch-up" job with ordinary cement; it required a specialized sequence to stop the corrosion and restore the ceiling's integrity overhead. The Buildrite Multi-Stage Repair System: • De-rusting: First, Rust Converter was applied to the exposed rebar. This chemical treatment transforms residual rust into a stable, protective layer, halting the corrosion process that causes concrete cancer. • Corrosion Protection: Epoxy Primer was then coated onto the steel to provide a high-performance barrier against future moisture and oxygen, ensuring the "cancer" would not return. • Structural Bonding: To ensure the new repair mortar would stay attached to the old ceiling, Confix HV (High Viscosity) was used as a bonding agent. This "tacky" epoxy ensures a monolithic bond between the old concrete and the new patch. Overhead Reconstruction: Finally, Concrete Patch V was applied. This is a specialized lightweight, high-strength mortar designed for vertical and overhead use. Unlike standard mortar, it is "sag-resistant," meaning it stays in place on the ceiling without falling during application. Why this system was critical for this renovation: • Structural Safety: By restoring the spalled areas, the structural load-bearing capacity of the floor was reinforced, making the home safe for the family again. • Comprehensive Protection: Simultaneously waterproofing the roof deck (the source of the leak) and repairing the ceiling (the result of the leak) provided a permanent, top-to-bottom solution. • Workability: Using "V" (Vertical/Overhead) grade mortar allowed the workers to achieve a smooth, flush finish on the ceiling without the need for complex formwork or support. Thanks to the technical assistance provided to the owner and Engr. Pabelonio, the renovation successfully transformed a deteriorating house into a safe, modern residence.

Scope of Work Installation of Exposed Polyurethane Waterproofing Membrane Location / Project Site Legazpi City, Albay Client Arch. Vincent Borabon Product Solution Buildrite Clever Sil (White) Project Reference Flat roofs are notoriously prone to water ponding and leakage if not protected by a high-performance system. For a two-story building in Legazpi City, Albay, Architect Vincent Borabon sought a reliable, modern solution that could withstand the region's heavy rainfall and intense heat. After inquiring about a system that balances durability with ease of use, we recommended Buildrite Clever Sil. This polyurethane-based system is specifically designed for exposed applications, meaning it does not require a protective concrete topping, which significantly simplifies the construction process. Why Arch. Borabon chose Clever Sil for this flat roof: • Thermal Regulation: By choosing White Clever Sil, the project gained excellent solar reflectivity. This "cool roof" effect reflects sunlight away from the building, reducing heat transfer into the interiors and lowering electricity costs for air conditioning. • Superior Material Density: Its dense molecular structure prevents water penetration even during periods of minor ponding, which is a common challenge for flat roof designs. • Flexibility and Strength: The membrane is highly elastic, allowing it to bridge cracks caused by the building's natural movement. Simultaneously, it offers good abrasion resistance, making it sturdy enough for regular walk traffic. • Efficiency: The system is economical and easy to apply using a roller. Because it is a single-component liquid, it creates a monolithic, seamless skin that eliminates the weak points (seams) found in traditional sheet membranes. Throughout the application, Buildrite's technical team provided on-site assistance to ensure the substrate was properly prepared and the membrane was applied to the correct dry film thickness. The result is a sleek, energy-efficient, and 100% watertight flat roof. Message Us Now Help us achieve our vision of becoming the standard of excellence in construction.

Scope of Work Transparent Over-Tile Waterproofing and Leak Repair Location / Project Site Churchill Mansion, Congressional Avenue, Quezon City Client Private Homeowner Product Solution Buildrite Epocoat TW Project Reference Bathroom leaks on the second floor of a home are a homeowner's nightmare, often leading to damaged ceilings below and the daunting prospect of a "hack-and-build" renovation. In a residence at Churchill Mansion, Quezon City, the second-floor bathroom suffered a waterproofing failure. The initial plan was to perform a traditional repair: hacking away all the tiles, reapplying a membrane, and installing new tiles—a process that is loud, dusty, expensive, and time-consuming. Seeking a more efficient alternative, the owner discovered Buildrite Epocoat TW. This specialized solution allowed the team to fix the leak without removing a single tile, preserving the original look of the bathroom while providing a permanent seal. The Advantages of the "Over-the-Tile" System: • Non-Destructive Repair: By applying the coating directly over the existing tiles and grout, the homeowner avoided the high cost of demolition and the price of purchasing replacement tiles. • Seamless Water Impermeability: Buildrite Epocoat TW is a two-component epoxy system that cures into a crystal-clear, tough "skin." It flows into the porous grout lines—where leaks usually begin—and seals the entire surface, making it 100% water-impermeable. • Industrial Strength: Despite being used in a residential bathroom, this product is engineered to be shock, chemical, and impact-resistant. It withstands the friction of daily foot traffic and the harsh chemicals found in household cleaners without peeling or clouding. • Rapid Turnaround: The application is as simple as using a brush or roller. This allowed the project to be completed in a fraction of the time required for a traditional renovation, saving significantly on labor costs. Technical Performance: • Clarity: It maintains the aesthetic of the original tiles, providing a subtle gloss while ensuring no water can seep through. • Durability: Once cured, it creates a hard-wearing surface that bridges the gaps between tiles, preventing the structural movement that often causes traditional grout to crack. By choosing Buildrite Epocoat TW, the homeowner successfully resolved a critical structural issue with a cost-efficient, modern approach that prioritized convenience and long-term protection.

Scope of Work High-Flexibility Athletic and UV-Resistant Floor Coating Location / Project Site Badoc, Ilocos Norte Client SK Chairman Ralph-Jhon Bacani Product Solution Buildrite Floortek Flex Project Reference Word-of-mouth and proven results are the most reliable indicators of product performance in public infrastructure. After observing the success of a similar project in Ilocos Norte, SK Chairman Ralph-Jhon Bacani sought to implement a professional-grade flooring system for the new basketball court in Barangay Gabut Sur, Badoc. Most barangay courts rely on "popular" or ordinary paints that quickly peel, fade, or become dangerously slippery under heavy use. Chairman Bacani’s goal was to provide the community with a facility that wasn't just visually appealing, but one that could withstand the high-impact demands of local sports while remaining safe and durable for years. The Buildrite Floortek Flex Advantage: • To ensure the project met provincial standards, Buildrite provided technical assistance throughout the application, shifting the focus from "standard painting" to "high-performance coating." • Impact and Shock Absorption: Unlike rigid paints, Buildrite Floortek Flex is a rubberized system. It is engineered to absorb the shock of high-impact activities, reducing the strain on players' joints and preventing the coating from ripping or tearing under the stress of sudden pivots and jumps. • Exceptional Flexibility: The coating moves with the concrete. In the high-heat environment of Ilocos Norte, this flexibility prevents the surface from cracking or delaminating during the natural expansion and contraction of the slab. • UV and Weather Resilience: Formulated specifically for exterior applications, the system features excellent UV resistance. This ensures the court maintains its vibrant colors and structural integrity despite constant exposure to intense sunlight and seasonal rains. • Safety-First Finish: The surface provides a consistent slip-resistant property, ensuring player safety even during high-speed gameplay. Its high abrasion resistance means it can handle heavy daily use without thinning or wearing down. Technical Collaboration: Through the endorsement and supply from T. Gamayo Construction Supply Inc., the project was executed with strict adherence to Buildrite’s application standards. By choosing a specialized athletic system over a generic paint, the leadership of Barangay Gabut Sur has secured a long-term asset for their youth, proving that "standard" is no longer enough for community sports.
