This technology involves processing FRP strands that have been impregnated and cured with resin into sheets, which are then adhered to the surface of concrete structures using a specialized adhesive for repair and reinforcement methods. It can be applied to reinforcement measures for cantilever slabs in concrete bridge decks and the upper parts of main girders. Additionally, it can be used for concrete slabs that suffer from insufficient strength due to floor slab improvements or the increased size of loading vehicles corresponding to the year of bridge construction. The effectiveness of this method increases particularly in areas with heavy traffic where road restrictions occur. 【Features】 ■ Immediate sheet application after surface preparation ■ Excellent workability without the need for resin impregnation or degassing ■ Short construction period and cost-effective ■ Simple and high quality ■ Significant reinforcement effect *For more details, please refer to the PDF materials or feel free to contact us.

This technology is a non-combustible material construction method certified by the Minister of Land, Infrastructure, Transport and Tourism, using a solvent-free inorganic silicone resin as the main component and a room temperature curing tunnel paint. It contains none of the 54 compounds subject to the Organic Solvent Poisoning Prevention Regulations and is characterized by extremely low volatile components. Dirt on the surface of the coating can be easily removed through simple cleaning operations. Additionally, the interior walls of the tunnel become beautifully bright, enhancing the lighting effect and improving visibility and safety. 【Features】 - Environmentally friendly - Contains none of the 54 compounds subject to the Organic Solvent Poisoning Prevention Regulations - Excellent pollution recovery - Inorganic and certified non-combustible material - Improvement of the tunnel interior environment and traffic safety measures *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce the "Protective Lining Method (Lifetex Method)." We offer various methods, including the "Lifetex LH Method," which combines the ability to prevent the intrusion of chloride ions, water, oxygen, and carbon dioxide—causes of concrete deterioration—with crack-following properties that can accommodate hairline cracks, as well as the "Lifetex LA Method," which maintains the performance of concrete spalling. You can choose according to your needs. 【Lineup】 ■ Lifetex LH Method ■ Lifetex LA Method ■ Lifetex V-FRP Method *For more details, please refer to the PDF document or feel free to contact us.

• Special Construction Method

The technology is a method for preventing spalling of concrete using continuous fiber FRP lattice reinforcement. The high-strength FRP lattice reinforcement supports the weight of detached concrete chunks, while the mesh net on the back prevents the fall of small pieces measuring less than a few centimeters. Additionally, since it does not integrate with the structure using resin-based adhesives or mortar, surface preparation and waterproofing or drainage treatment are unnecessary, allowing for installation even on wet surfaces with leaks or condensation. 【Features】 ■ Installation is quick as it only requires anchoring to the structure. ■ No curing or drying time is needed, allowing for a shorter construction period. ■ Suitable for short-duration work at night. ■ Can be installed across joints. ■ Visual inspection of the substrate is possible through the mesh net. *For more details, please refer to the PDF document or feel free to contact us.

• Special Construction Method

The "FRP Grid Reinforcement Method" is an FRP lattice reinforcement made by integrally molding high-performance continuous reinforcement fibers such as carbon aramid and glass that are impregnated with resin. It has a very low specific gravity, and since the lattice intersections are on the same plane, its cross-section is thinner compared to rebar. Additionally, it is easy to transport, does not require heavy machinery, and is not restricted by construction space. 【Features】 ■ Thin and light ■ High reinforcement effect ■ No corrosion ■ Complies with RC design methods ■ Thinner cross-section compared to rebar *For more details, please refer to the PDF materials or feel free to contact us.

• Special Construction Method

The technology is a system that automatically sprays clean water at ultra-high pressure (around 50 MPa) to collect wastewater. It involves a coordinated unit assembly operation and performs non-contact construction on concrete surfaces, eliminating the risk of noise, vibration, and dust pollution. As a result, it resolves issues related to tunnel cleaning, restores illumination, improves visibility, and enhances the safety of vehicles in operation. 【Features】 - Automatically sprays clean water at ultra-high pressure (around 50 MPa) and collects wastewater - Coordinated unit assembly operation - Non-contact construction on concrete surfaces - No risk of noise, vibration, or dust pollution *For more details, please refer to the PDF materials or feel free to contact us.

• Special Construction Method

Introducing the "Sodium Bicarbonate Blast Method (SBS Method)." Sodium bicarbonate, commonly known as baking soda, is widely used as a food baking powder. It is also effective as a cleaning agent, releasing carbon dioxide at 270 degrees and forming a colorless solid that exhibits mild alkalinity in its aqueous solution. This technology allows for the suppression of impact force at low pressure. The effect of baking soda enables the removal of oily substances. 【Features】 ■ Baking soda is water-soluble and non-toxic ■ Cleaning power can be adjusted by combining shot materials and pressure ■ Impact force can be suppressed at low pressure ■ The effect of baking soda allows for the removal of oily substances *For more details, please refer to the PDF document or feel free to contact us.

• Special Construction Method

This technology is a reinforcement method that achieves effects equivalent to steel plate reinforcement by bonding carbon fiber sheets to the surface of concrete structures using an epoxy-based room temperature curing resin. The specific gravity is about 1/4 to 1/5 that of iron. The tensile strength is approximately 10 times that of iron (1,900 to 3,400 N/mm²). Additionally, it has characteristics that make it suitable for corrosive environments such as salt damage. 【Features】 ■ Lightweight ■ High strength ■ High elasticity ■ High durability ■ Reinforcement effect *For more details, please refer to the PDF materials or feel free to contact us.
