The "Toreka Cross Method" is a reinforcement technique for concrete structures using high-quality carbon fiber Toreka cloth. When resin is impregnated, it changes from white to transparent. The impregnation state can be visually confirmed during construction, making it easy to prevent human errors such as unimpregnated areas. By applying Toreka cloth in the vertical direction (bending reinforcement) and horizontal direction (shear reinforcement), the concrete is constrained, resulting in increased ultimate displacement and improved seismic performance. [Reinforcement Effects] ■ Seismic reinforcement for bridge piers and buildings ■ Improved compressive toughness ■ Enhanced bending strength ■ Reinforcement of crack areas *For more details, please download the PDF or feel free to contact us.

"Toughron Wood P" is a repair/reinforcement agent specifically designed for the repair and reinforcement of foundations and bases, which are fundamental to seismic reinforcement. By using aramid fibers on the surface of the wood in conjunction with this product, the adhesive strength, reinforcement strength, and seismic strength are significantly enhanced. Additionally, we offer "Toughron Wood GII," which is suitable for preventing damage to wood from termites. The pressure during injection allows the liquid to penetrate deep into the wood, making it strong and durable. 【Features】 ■ Two-component, room temperature curing type ■ Excellent chemical resistance, including to sulfuric acid ■ Superior mechanical strength and weather resistance ■ Can be applied to wet surfaces and has excellent flame retardancy ■ Strong adhesion to wood and metal *For more details, please download the PDF or feel free to contact us.

"Continuous fiber reinforcement" refers to a reinforcement method using continuous fiber sheets that is gaining attention as a repair and reinforcement technology for concrete structures. The fibers used are lightweight, high-strength, and durable aramid fiber sheets or carbon fiber sheets, which are adhered to the surface of the concrete to create a thin reinforcement layer, providing bending reinforcement and tensile-shear reinforcement. Additionally, it can be applied using roller brushes or de-bubbling rollers, making it highly effective for construction in narrow spaces beneath floors. 【Product Lineup (Partial)】 ■ Primer (Base Coat) ・TW-1P (Single Component) ■ Teflon (Injection/Filling) ・G-2030 ・G-250 *For more details, please download the PDF or feel free to contact us.

Even if the concrete is chipped as shown in the photo, it is possible to carry out repairs. First, clean the bonding surface with a grinding process and carefully apply rust-inhibiting primer (Asahi Bond Rust-Inhibiting Primer) to the rebar sections. Next, use epoxy resin (Tafron G-2030) to inject into the joint area to prevent any gaps. After that, evenly apply epoxy mortar (Asahi Bond BE13) to the joint area. This process is similarly applied to the side of the chipped concrete. Finally, ensure that the joint is firmly adhered and take measures to support it from below with wood to prevent any falling.

What is a steel post? A steel post is a metal support used as a "post" to support the underfloor of houses and buildings. Compared to traditional wooden posts, it excels in durability, strength, and ease of installation, playing an important role in preventing floor sagging and sinking. Features of steel posts ✅ High durability Made of steel, they are resistant to corrosion and do not have the risk of termite damage like wooden posts. They excel in water resistance and weather resistance, maintaining stable strength over a long period. ✅ High strength They have a higher load-bearing capacity than wooden posts, effectively preventing floor sinking and sagging. They are especially ideal for placing heavy furniture or enhancing seismic resistance. ✅ Adjustable height Equipped with a screw-type adjustment feature, they can be finely adjusted to match the floor height. Maintenance after installation is also easy, allowing for a level floor to be maintained for a long time. ✅ Easy installation Lightweight and easy to handle, they can accommodate various installation methods such as screw fastening, adhesive fixing, and bolt fixing. They are also ideal for renovations and reinforcement work. ✅ Economical and excellent cost performance They last longer than wooden posts and require less maintenance, making them superior in cost performance in the long run.

【Product Introduction】Tafron Wood G2 ― High-durability, weather-resistant treated wood that protects from within ― Tafron Wood G2 is a high-performance treated wood that penetrates anti-decay and anti-termite components deep into the core of the wood through pressure injection of a specialized chemical. It demonstrates stable durability over long periods even under harsh conditions such as contact with the ground and humid environments.
