고객 리뷰
John Doe
Construction Manager (USA)
“We’ve used Great Ocean’s TPO waterproof rolls on three commercial roof projects in Texas, and the performance is outstanding. Even through scorching summers and heavy rainstorms, there’s zero leakage. What impresses me most is the durability—installed 3 years ago, they still look and function like new. The team’s technical support on installation guidelines was also top-notch.”
Maria Garcia
Distributor (Brazil)
“As a distributor in South America, I value reliability and consistency, and Great Ocean delivers both. Their PVC waterproof rolls have become our best-sellers because of their high quality-to-price ratio. Customers love how easy they are to work with, especially on curved surfaces. Shipment times are always on schedule, which makes our inventory management smooth—no more last-minute delays.”
Amara Okafor
Homebuilder (Nigeria)
“Waterproofing is critical in our tropical climate, and Great Ocean’s polymer cement coatings are a game-changer. They dry quickly even in humid conditions, and we’ve had zero complaints from homeowners about damp walls or mold. What’s more, their customer service team is responsive—when we had a question about application in heavy rainfall, they sent a detailed guide within hours. Trustworthy partner!”
Luca Rossi
Landscaper (Italy)
“We specialize in green roof projects, so root-resistant waterproofing is non-negotiable. Great Ocean’s metal-core root-resistant rolls have been perfect—they stand up to aggressive plant roots while keeping water out. Clients love that they’re eco-friendly too, which aligns with our sustainability goals. It’s rare to find a product that balances performance and environmental responsibility so well.”
Carlos Mendez
Restoration Contractor (Mexico)
“Restoring old buildings in Mexico City means dealing with uneven surfaces and frequent rain, so we need waterproof materials that adapt. Great Ocean’s spray-on rubber asphalt coating is a lifesaver—it seals every crack and irregularity perfectly. We used it on a 50-year-old office building last year, and there’s not a single leak despite heavy monsoons. The local team also appreciates that it’s low-odor, making on-site work more comfortable.”
Priya Patel
Agricultural Facility Owner (India)
“Our greenhouse in Gujarat needs reliable waterproofing to protect crops from heavy monsoons. Great Ocean’s polyethylene polypropylene rolls have been exceptional—they’re tough enough to handle daily exposure to sunlight and moisture, and they don’t degrade easily. We also use their cement-based crystalline coating for the facility’s concrete floors, which has stopped water seepage entirely. For agricultural businesses, durability and affordability matter most, and this brand delivers both.”
Thomas Jensen
Marine Engineer (Denmark)
“Marine structures like piers face constant saltwater exposure, so we need waterproof materials that resist corrosion. Great Ocean’s PVC waterproof rolls with anti-corrosion additives have exceeded our standards. We installed them on a coastal pier in Copenhagen 2 years ago, and they show no signs of salt damage—something even premium European brands struggle with. Their technical team also provided customized advice for saltwater environments, which made the installation seamless.”
Nomsa Dlamini
Hotel Manager (South Africa)
“Our hotel’s rooftop pool and outdoor areas need waterproofing that can handle both intense sun and sudden thunderstorms. Great Ocean’s high-elastic liquid membrane coating has been perfect—it’s flexible, so it doesn’t crack when the temperature changes, and it keeps the pool area dry even after heavy rains. Guests often comment on how well-maintained the outdoor spaces are, and this product is a big reason why. Plus, the quick drying time meant we didn’t have to close areas for long during application.”
