A formwork that serves as insulation material made from domestically sourced thinned wood, which does not emit toxic gases when burned or buried.
This is an insulation material that also serves as a formwork, recognized by the Ministry of Land, Infrastructure, Transport and Tourism (formerly the Ministry of Construction) as an alternative to conventional formwork plywood.
Eliminate waste and reduce costs! Achieve high rust prevention effects and lightweight design.
The "remaining formwork" refers to thin concrete formwork that does not need to be removed after concrete pouring and curing. The formwork panel "Protect Make Pierce," which is treated with double-coated cationic electrodeposition painting for epoxy coating as a rust prevention measure, prevents damage to the interior of the concrete. Due to its high internal rust prevention effect, the panel itself can also be made thinner. Not only does it provide rust prevention, but it also achieves weight reduction. 【Features】 ■ Shortened construction period ■ Improved safety ■ Reduced construction waste ■ Total cost reduction *For more details, please refer to the catalog or feel free to contact us.
![Drop-in type high-durability wooden residual formwork construction [for retaining walls on steep slopes] with consideration for landscape!](https://image.www.ipros.com/public/product/image/54a/2000679106/IPROS85905248925568609637.jpeg?w=280&h=280)
High durability and consideration for the landscape! Conservation of the surrounding environment can be achieved! No need for formwork removal or scaffolding, shortening the construction period!
"The drop-in type high-durability wooden residual formwork construction" achieves long-term durability through unique wood preservation technology! It promotes the use of wood and contributes to the global environment. The estimated lifespan based on decay test results is over 50 years. The risk of aesthetic deterioration due to decay, as seen with conventional wooden residual formwork, and the danger of formwork components falling off are extremely low, eliminating the need for maintenance and inspection work. It can be used for the formwork of retaining walls to prevent disasters in areas at risk of landslides on steep slopes. The wooden surface reduces sunlight reflection more than concrete. There is no need for scaffolding during formwork assembly (installation of a catwalk for pouring). The elimination of formwork and scaffolding removal, as well as concrete surface finishing, allows for a shortened construction period. It can be assembled by ordinary workers without the need for specialized formwork carpenters. 【Features】 ■ The surface finish of the structure is wood-based, considering aesthetics. ■ Conservation of the surrounding environment is achieved. ■ The removal of formwork and concrete surface finishing is unnecessary, and since scaffolding for those tasks is also not needed, the construction period can be shortened. ■ Direct sunlight reflection can be prevented. *For more details, please refer to the PDF document or feel free to contact us.

High durability with consideration for the landscape! Conservation of the surrounding environment can be achieved! No need for formwork removal or scaffolding, shortening the construction period!
"The drop-in type high-durability wooden residual formwork construction" achieves long-term durability through unique wood preservation technology! It promotes the use of wood and contributes to the global environment. The estimated lifespan based on decay test results is over 50 years. Conventional wooden residual formwork poses risks due to deterioration affecting aesthetics and the potential for formwork components to fall off, making its use common on the upstream side. Our products enable use on the downstream side due to their high durability. Maintenance and inspection work to prepare for decay or the detachment of formwork components are unnecessary. There is no need for scaffolding during formwork assembly (installation of a catwalk for pouring). The elimination of formwork and scaffolding removal, as well as concrete surface finishing, leads to a reduction in construction time. Assembly can be done by ordinary workers without the need for formwork carpenters. [Features] ■ The surface finish of the structure has a wooden texture, considering aesthetics. ■ Conservation of the surrounding environment is achieved. ■ The removal of formwork and concrete surface finishing is unnecessary, and scaffolding for those tasks is also not required, resulting in a shortened construction period. ■ Direct sunlight reflection can be prevented. *For more details, please refer to the PDF materials or feel free to contact us.

Reduce the total cost of concrete construction. Contribute to improving safety, labor-saving, and efforts towards SDGs.
The "Residual Formwork Method" is a construction technique where the formwork used for pouring concrete is left in place as part of the structure after the concrete has been poured, without being removed. It utilizes thin precast cement concrete formwork products that incorporate reinforcement materials and assembly components. This eliminates the need for demolding and transportation work, allowing for a reduction in construction time. Additionally, since scaffolding is not required, it contributes to improved safety. Furthermore, it helps reduce construction waste, leading to a decrease in environmental impact and supporting efforts towards the SDGs. 【Features】 ■ Significant reduction in total costs for concrete work due to shortened construction time, improved safety, and reduced construction waste. ■ The steel reinforcement embedded in the formwork uses a "double coat cationic electrodeposition coating (epoxy resin electrodeposition coating)" that excels in rust prevention. ■ Effective in various sites such as roads, tunnels, bridges, and dams. ■ Over 12,000 construction achievements annually. ★ A photo collection of construction examples is currently available. Please view it from "PDF Download." Feel free to contact us with any inquiries.
