K-CRAFT Co., Ltd., based in Kishiwada City, Osaka, performs repair and reinforcement work on concrete structures throughout Japan.Although we have only been in business for a short time, we have a large number of experienced employees, and we are able to perform high-quality construction in a short period of time using the high level of technology we have cultivated over the years. And, We also incorporate advanced construction methods that are difficult for other companies to construct, allowing us to handle a wide variety of situations. We maintain our own procurement channels for materials and supplies, which contributes to reducing overall construction costs while assuring safe and reliable construction.
Repair problems such as lifting, delamination, spalling, and internal defects in concrete structures caused by age-related deterioration. After conducting a preliminary exterior wall survey and diagnostic survey to check for peeling, spalling, and floating areas of concrete, we remove the deteriorated concrete and repair it with a cross-sectional repair material suited to the situation.
To prevent accidents involving damage or falling of concrete structures, the durability of the entire structure is improved by applying resins or impregnating materials to the concrete surface. It is effective not only in protecting newly constructed concrete such as bridge girders and tunnels, but also in improving the durability of concrete structures that have deteriorated over time.
By wrapping carbon fiber sheets, which are characterized by their light weight and corrosion resistance, around the surface of the existing concrete structure frame, the overall rebar volume is supplemented, resulting in shear and bending resistance and crack initiation suppression. CarbonFiber sheets can be applied to seismic retrofitting of a wide range of buildings in recent years, including RC reinforced concrete columns and beams, schools, and hospitals, and are used for a wide range of purposes.
A connecting device is installed on the bridge girder, and steel brackets are installed on the abutment to connect the upper and lower sections with connecting cables, etc., to prevent the bridge from falling during an earthquake. The piers are reinforced with carbon fiber sheets and other materials to improve their seismic resistance and protect lifelines, which are important for rescue and transport of supplies in the event of a disaster.
We can also provide you with civil engineering and construction materials.
We have a variety of manufacturer's materials available, and we can select materials that meet specification standards and calculate quantities. Our professional staff will quickly provide you with the best materials under various site conditions.
