In civil engineering sites, there are many opportunities to use temporary roadways, access roads, heavy machinery work yards, and material storage areas with sheets. Until now, steel plates have been widely used, but there is a growing interest in temporary materials made from wood due to environmental considerations and CO2 reduction. Hyper CLT sheets are civil engineering CLT materials made from wood CLT. As wooden sheets, they can be used for mud prevention, ground protection, ensuring work pathways, and as a substitute for steel plates. The 5×10 sheet weighs about 230 kg, and the 5×20 sheet weighs about 460 kg, making them lightweight and reducing the burden of transportation, installation, and removal. Wood has the property of fixing CO2, and further improvements in transportation efficiency can be expected due to its lightweight nature. These materials also help improve the site environment by reducing glare and noise. In public works, they are easy to use as materials for environmental considerations, safety measures, and creative proposals, making them recommended for companies aiming to enhance site evaluations. Please consider them as a new sheet selection for civil engineering sites, registered as "TH-250021-A" in the Ministry of Land, Infrastructure, Transport and Tourism's NETIS. We can provide proposals tailored to site conditions, from public works to private civil engineering projects.

Metal cracks are one of the concerns in equipment maintenance operations. Repairs using conventional welding methods can alter the base material around the crack due to heat, leading to residual stress and deformation, which always carries the risk of "crack recurrence" or "secondary damage." Hinode Waterworks Equipment Co., Ltd.'s "Mechanical Stitching Method" is a new technique that allows for the repair of metal cracks without applying heat. By using special bolts and reinforcement plates, the crack is physically removed without affecting the base material with heat. Repairs can be performed even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized.
