Company information

More good things for people, cities, and the environment.

Since our founding in 1945, Hamacast has been creating "good things" that no one can imitate. We develop and manufacture unique exterior materials and waterproofing materials, such as high-design stone-like exterior materials that replicate natural stone and excel in weather resistance and stain resistance, as well as tile exterior wall renovation methods that are highly safe and durable. We also offer waterproofing methods that combine over 40 years of experience and achievements in complex waterproofing techniques with added insulation and durability. Furthermore, our strength lies in our "complete responsibility construction," which ensures consistent quality and performance by managing all stages of construction and aftercare. By maximizing this strength, we respond to our customers' needs by enhancing the asset value of buildings and reducing maintenance and renovation costs. Moving forward, we will continue to explore without compromise to shape the values of a new era, consistently creating "good things" for people, communities, and the environment.
