Scope of Work Floor Refinishing, Moisture Mitigation, and Sports Surface Coating Location / Project Site Marcos Sports and Cultural Center, Badoc, Ilocos Norte Client Municipal Engineer Emman dela Cuesta (LGU Badoc) Product Solution Buildrite Epocoat MB / Buildrite Polycoat Flex Project Reference Public sports centers are the heart of local communities, but they also endure some of the highest levels of wear and tear—from intense sports matches to large-scale cultural gatherings. Municipal Engineer Emman dela Cuesta faced the challenge of refinishing the aging floors of the Marcos Sports and Cultural Center in Badoc, Ilocos Norte. As a loyal partner of Buildrite, Engr. Emman knew that simply painting over an old floor wouldn't suffice. Sports floors built on ground-level slabs often suffer from "rising damp" or moisture vapor, which can cause new coatings to peel, bubble, or delaminate. To ensure a "brand new" look that lasts for decades, we implemented a high-performance moisture-barrier and athletic-coating system. The refinishing process focused on two critical layers of protection: The Moisture Shield: Buildrite Epocoat MB (Moisture Barrier) was applied as the primer. This specialized epoxy layer acts as a permanent seal against moisture vapor coming from the ground. By blocking this pressure, it ensures that the decorative topcoat stays firmly bonded to the slab, even during the humid seasons of Ilocos Norte. The Resilient Finish: For the final surface, Buildrite Polycoat Flex was selected. This polyurethane (PU) rubberized coating is the gold standard for multi-purpose halls. It provides: • Shock Absorption: Protects the joints of athletes during high-impact sports. • Abrasion Resistance: Withstands the heavy foot traffic and chair movement common during cultural events. • Seamless Hygiene: A monolithic surface that is easy to clean and maintain, with no grout lines or joints to collect dirt. Thanks to the collaboration between the Municipality of Badoc, T. Gamayo Construction Supply, and Buildrite’s technical team, the Marcos Sports and Cultural Center has been successfully transformed. The result is a vibrant, durable, and professional-grade facility that is ready to serve the community for many years to come.

Scope of Work Concrete Stair Surface Protection and Aesthetic Finishing Location / Project Site Apartment Building, Gagalangin, Tondo, Manila Client Aljomitri Corporation Product Solution Buildrite Epocoat FC Project Reference Stairs in apartment buildings are high-traffic zones that endure constant friction and impact. While many owners traditionally turn to tiles, they often face issues with cracked grout lines, chipped edges, and the "hollow" sound of delaminating tiles. For a commercial apartment project in Tondo, Manila, Aljomitri Corporation opted for a modern alternative: a high-performance epoxy coating. The owner chose Buildrite Epocoat FC to achieve a sleek, industrial, and professional look. By applying a light gray finish, the stairwell was instantly brightened, improving visibility for residents while providing a surface that is significantly easier to sanitize than traditional tiled stairs. Why Epocoat FC was the Ideal Choice for Stairs: • Exceptional Adhesion: As a polyamide-cured epoxy, it forms a powerful chemical bond with the concrete. This prevents the peeling or flaking often seen with standard floor paints when subjected to the "shearing" force of people climbing up and down. • Hard yet Flexible: While the coating cures to a very hard finish to resist scratches, it retains enough flexibility to handle the minor vibrations and structural movements inherent in multi-story staircases. • Seamless and Hygienic: Without grout lines, there is nowhere for dirt or bacteria to hide. This makes the stairs incredibly easy to sweep and mop—a vital feature for communal living spaces. • Safety Integration: To address the inherent slip risk of smooth coatings, the contractor installed stair nosings (safety strips) at the edge of each step. This combination provides the clean look of epoxy with the mechanical grip needed for safe transit. Technical Features of Epocoat FC: • Two-Component System: Ensures a consistent chemical cure that is far more durable than one-part water-based paints. • Impervious Barrier: Protects the underlying concrete from water, oils, and common household cleaning chemicals. • Multi-Substrate Versatility: While used on concrete here, it is also highly effective for protecting steel and wooden surfaces.

Scope of Work Comprehensive Positive and Negative Side Waterproofing and Chemical-Resistant Lining Location / Project Site Tacloban City Client ZTATIK Engineering and Services Product Solution Buildrite Crystor / Buildrite Blockout ETL / Buildrite Epocoat MB / Buildrite Clever Sil / Buildrite Sapal 2-in-1 / Buildrite Leak Plug Project Reference Waterproofing a 400 cubic meter cistern tank is a high-stakes engineering challenge. At this scale, the hydrostatic pressure is immense, and even a minor failure can lead to catastrophic water loss or structural degradation. To eliminate the risk of "backjobs" (costly re-work), ZTATIK Engineering and Services partnered with Buildrite to implement a full-system solution for a project in Tacloban. The strategy involved a "belt and braces" approach, treating both the positive side (the surface in direct contact with water) and the negative side (the exterior/opposite side of the wall) to ensure total containment. The technical system utilized a specialized array of Buildrite technologies: • Emergency Leak Termination: Buildrite Leak Plug was used to instantly seal any active seepage points or honeycombs discovered during the initial inspection. • Crystalline Technology: Buildrite Crystor was applied to the concrete substrate. This material penetrates deep into the concrete pores, reacting with moisture to grow non-soluble crystals that permanently block water pathways from within. • Potable Water Protection: For the internal lining, Buildrite Blockout ETL was utilized. This epoxy-based coating is specifically designed for drinking water contact, providing a seamless, non-toxic, and chemical-resistant barrier. • Moisture & Joint Management: Buildrite Epocoat MB acted as the moisture barrier primer, while Sapal 2-in-1 was used as a flexible sealant for joints and penetrations to accommodate structural movement. • Exterior Shield: Buildrite Clever Sil was applied to the external surfaces to provide an elastic, weather-resistant membrane that prevents groundwater or rain from ingress through the negative side. By combining crystalline penetration with high-performance coatings, ZTATIK Engineering ensured that this 400-cubic-meter infrastructure is leak-proof and structurally protected for decades. Buildrite provided on-site technical assistance throughout the application to guarantee that every product was applied to the highest industrial standards.

Scope of Work Structural Retrofitting and Tensile Strength Enhancement via Carbon Fiber Reinforced Polymer (CFRP) System Location / Project Site Public Bridge, Cebu Client Department of Public Works and Highways (DPWH) Product Solution Buildrite Carbon Fiber Fabric / Buildrite Carbon Fiber Laminating Epox Project Reference Infrastructure aging is a critical concern for public safety, especially for bridges that serve as vital economic arteries. In Cebu, a major bridge began showing signs of deflection—a visible sagging or bowing that indicates the internal steel reinforcement may no longer be sufficient for the current traffic load. The DPWH faced a significant logistical challenge: the bridge needed immediate structural rehabilitation, but closing it would cause massive traffic congestion and disrupt local operations. Traditional "concrete jacketing"—which involves adding heavy steel rebars and pouring new concrete—was ruled out because it is labor-intensive, heavy, and requires long curing times that would force a total shutdown. The Solution: Buildrite Carbon Fiber System To restore the bridge’s integrity without stopping traffic, the DPWH utilized Buildrite Carbon Fiber Fabric. This advanced material allows for "external reinforcement," acting like a high-strength skin that bonds to the existing concrete. Why the Carbon Fiber System was the Strategic Choice: • Immense Tensile Strength: Buildrite Carbon Fiber Fabric boasts a tensile strength of 120,000 psi. When bonded to the underside of the bridge, it effectively takes over the tension loads, arresting further deflection and significantly increasing the structure's load-bearing capacity. • Minimal Dead Load: Unlike concrete jacketing, which adds tons of weight to the structure, Carbon Fiber is extremely lightweight. It strengthens the bridge without adding significant stress to the original foundations. • Rapid Installation: The fabric is "laminated" to the concrete using Buildrite Carbon Fiber Laminating Epoxy. This process is much faster than traditional masonry work, allowing crews to work in sections or during off-peak hours, ensuring the bridge remains operational. • Economic Efficiency: By reducing the need for heavy machinery, extensive formworks, and long-term road closures, the total project cost—including labor and time—is significantly lower than conventional methods. Technical Performance: • Corrosion Resistance: Unlike steel, Carbon Fiber does not rust, providing a long-term solution against the salty, humid air of Cebu. • Monolithic Bonding: The specialized Laminating Epoxy ensures that the fabric and the old concrete work together as a single structural unit, restoring the safety of the bridge for the commuting public. By choosing Buildrite Carbon Fiber Fabric, the DPWH successfully extended the lifespan of a critical piece of Cebu's infrastructure through a modern, non-invasive, and highly efficient engineering approach.

Scope of Work Structural Leak Repair, Waterproofing Membrane Replacement, and Protective Topping Application Location / Project Site Poblacion Ibajay, Aklan Client Den Sabilano (Homeowner) Product Solution Buildrite Flexicrete / Buildrite Leak Plug Project Reference Another roof deck was saved from a faulty flexible cementitious waterproofing system! In this project, a residential house in Poblacion Ibajay, Aklan, was suffering from persistent leaks caused by a failed waterproofing application. According to the owner, Den Sabilano, the previously used "flexible cementitious membrane" caused recurring headaches. They were forced to reapply new layers every few months due to frequent leaks, leading to a build-up of ineffective material. Finally, they decided it was time for a permanent fix. This is where we stepped in to provide a professional-grade solution. The rehabilitation process required the labor-intensive removal of several layers of the old, failed membrane to expose the bare concrete. Once the surface was prepared, we used Buildrite Leak Plug to seal active seepage and cracks, followed by the application of Buildrite Flexicrete. Because Flexicrete is a specialized flexible cementitious waterproofing membrane designed for heavy-duty protection, it requires a topping to shield it from direct UV exposure and mechanical wear. By following this system—waterproofing followed by a protective topping—the owner now has a roof deck that is built to last, ending the cycle of constant repairs.
