Changzhou Kanghong Waterproof Material Co., Ltd.
is a seasoned manufacturer dedicated to building waterproofing and thermal insulation systems. With dual production bases in Changzhou (Jiangsu) and Dongying (Shandong), we have nearly 40 years of professional R&D and production experience. Our in-house brand Qingmingshan delivers highly weather-resistant products that perform stably in harsh environments of high temperature, high humidity, strong UV rays and long rainy seasons. Boasting a registered capital of 10.58 million RMB, we independently produce four core product lines: polymer waterproof membranes, professional waterproof coatings, wall thermal insulation materials, and engineering anti-crack fibers. Supported by large-scale production capacity and the Yangtze River Delta’s superior port logistics, we offer global sea freight with short lead times and cost-effective procurement solutions, serving bulk engineering orders and customized distribution for local building material retailers.Our optimized weather-resistant product portfolio solves diverse building leakage issues, covering residential buildings, commercial complexes, industrial plants, roof renovations, basements and coastal constructions.
Our flagship export polymer waterproof membrane features high elasticity, outstanding hydrolysis and UV resistance, and excellent resistance to thermal deformation and coastal salt spray, effectively lowering long-term maintenance costs for large-scale infrastructure and indemnificatory housing. The eco-friendly water-based waterproof coating is high-tensile and mildew-proof, applicable on damp surfaces for rainy-season construction, ideal for balconies, kitchens, bathrooms and flat roofs with simple and efficient operation. We also provide integrated wall thermal insulation & waterproof materials compliant with green building standards for industrial and residential exterior walls, as well as specialized anti-crack & anti-seepage fibers for cement and mortar layers. Supporting one-stop procurement of complete waterproofing systems, our auxiliary materials greatly reduce customers’ docking and purchasing costs.
Our versatile products are widely applied in civil real estate, industrial infrastructure, municipal engineering, old building renovation and coastal tourism construction projects. Adhering to high weather resistance, cost performance and one-stop integrated supply, we leverage mature Chinese waterproof manufacturing technology to serve global clients. We warmly welcome building material wholesalers, engineering companies and real estate developers worldwide for long-term partnerships. We provide customizable product specifications, packaging and labels to meet local market regulations, along with stable supply, professional technical support and efficient logistics. We aim to solve tropical building leakage problems together with partners, exploring the global waterproof material market and achieving win-win cooperation.
