Yamau offers permanent decorative formwork systems, including "Yu Panel" and "Stone-chan." The Yu Panel eliminates the need for bolts and other fastening hardware, simplifying the installation process. Its interlocking design allows for easy assembly without caulking. The Stone-chan blocks are self-supporting and can be installed without formwork or scaffolding, promoting labor savings, reduced manpower, and resource efficiency. The blocks are secured with connecting hardware, ensuring safe and efficient installation.
Founded in 1953, Yamau has over half a century of experience in manufacturing and selling concrete products for civil engineering and construction. They develop environmentally conscious products suited to Japan's climate and conditions, focusing on resource efficiency. Yamau uses recycled slag as aggregate and eliminates the need for formwork-specific hardware to conserve resources and cut costs. Their diverse operations include concrete product installation, construction and civil engineering design consulting, and more.
Yamau leverages decades of concrete manufacturing expertise to develop innovative products and methods tailored to various needs. They promote precasting, where concrete products are manufactured in a factory and transported to the site, ensuring high-quality products unaffected by weather conditions and enhancing labor efficiency. This approach is applied to a wide range of structures, including roads, rivers, agricultural facilities, and ports.
Yamau's permanent decorative formwork has been used in various projects, such as erosion control works employing Yu Panel with cobblestone patterns and volcanic erosion control works using Stone-chan. Stone-chan was developed to suit specific site requirements, such as those found in national parks where traditional formwork was not feasible. Formwork needs to be tailored to the construction site, suitable not only for civil engineering but also for residential and commercial building projects. Selecting the appropriate formwork for the construction type is crucial.
Yamau's permanent decorative formwork systems are highly efficient and suitable for various civil engineering projects. These systems, designed for ease of assembly and improved work efficiency, reduce labor and construction time. Some system formwork can be reused multiple times, significantly lowering costs. When selecting system formwork, it is essential to consider the construction type and consult with the manufacturer to ensure compatibility and efficiency.
