Permanent formwork uses thin concrete formwork that does not need to be removed after concrete pouring and curing. Typically, formwork must be dismantled and removed after pouring, which involves significant labor and waste disposal issues.
Permanent formwork not only shortens construction periods and reduces costs but also offers an environmentally friendly solution. The following is a brief introduction to the features and basic information about products of Japanese manufacturers that handle permanent formwork, including system formwork.
Arman offers the "Super Compane-kun" permanent formwork method. In addition to permanent formwork, they provide panel formwork, decorative formwork, concrete formwork, and slope construction services. Their formwork solutions can reduce the work of excavation and backfilling on the rear side, as well as the process of production and dismantling of formwork. Therefore, the concrete curing period can also be shortened. The easy installation work is another advantage since it does not require skilled workers.
Takamura Sogyo handle permanent decorative formwork "Prote Rock Make" and permanent formwork "Prote Rock Pierce Wonder." These formworks utilize a technology that forms two different types of electro-deposited coatings on the steel reinforcements inside the formworks, enhancing the rust prevention performance at the end faces. This prevents concrete from expanding and cracking due to rust, while also offering a variety of patterns and color variations on the panel surfaces.
Yamau offers permanent decorative formwork "Yuu Panel" and "Stone-chan." These system formworks eliminate the need for special fittings and bolt tightening on-site. They achieve labor-saving, manpower reduction, and resource conservation with formwork-free, scaffolding-free methods. Their long-standing concrete manufacturing technology is applied to various civil engineering sites.
Ooike provides permanent formwork that is easy to assemble and process, enhancing safety and reducing construction waste. Their formworks are lightweight, rust-resistant, and available in a variety of decorative patterns such as split stone. They do not require removal after formwork installation, helping to reduce costs.
Mason uses lightweight composite panels in their permanent formwork method. Widely used in civil engineering projects such as retaining walls, these formworks are not only durable and fire-resistant but also easy to assemble. Utilizing these formworks can lead to labor savings, reduced workload, and cost reduction.
Nippon Steel Engineering offers the "S-Form®," a buried type steel formwork for parapets and curbs used in bridge construction. Made from "Super Dyma®," a highly corrosion-resistant plated steel sheet developed by Nippon Steel, these formworks are durable and resistant to rust, making them suitable for bridges exposed to the elements.
Seino Construction provides the SISJ method, a construction method using formwork for reinforced concrete wall structures. This method uses two fire-resistant expanded polystyrene board formworks that can be stacked like building blocks. They also offer formwork suitable for large walls and construction slabs, helping to reduce costs and shorten delivery times.
Maruei Concrete Industry, a specialist in concrete secondary products, offers the permanent formwork method for slope embankment. All products are factory-made, ensuring high-strength, high-quality concrete that is dense and durable. Machine installation shortens construction periods and reduces accidents during construction.
Maruman Concrete provides two types of permanent formwork blocks: "Prote Rock Pierce Wonder" and "Prote Rock Make". "Prote Rock Pierce Wonder" is available in three varieties (Pierce, Wonder, Mini), focusing on functionality, while "Prote Rock Make" offers aesthetic qualities, allowing products to be used according to their application.
Kyowa Concrete Industry offers a wide range of permanent formwork products such as the "EK Wall" and "Biofilm." These products are suitable for various locations, including fishing ports, dams, and parks, and enhance work safety and efficiency. With extensive experience in manufacturing concrete blocks for embankments, they also develop environmental products for rivers, roads, and fish reefs.
TOYOTA FORMS manufactures concrete formwork for environmental, river, and civil engineering projects. Valuing craftsmanship, they emphasize an "attention to detail" approach even in unseen areas, focusing on customer-oriented thinking. Their formworks are designed for ease of use and productivity, contributing to cost savings.
