In concrete structures, the infiltration of water from rainwater and groundwater, as well as the penetration of salts from de-icing agents, airborne salt, and seawater, can induce corrosion and rusting of rebar, leading to spalling defects and a reduction in the strength of the structure. In response to incidents such as concrete block falls in tunnels and spalling accidents from elevated bridges, clients are creating their own standards to prevent concrete spalling and are collectively working on countermeasures. To address these issues, we recommend the 'Regitect RT Method,' a specification for preventing concrete spalling that satisfies performance criteria without using fibers as tensile reinforcement.

Introduction of the optimal protection system for exterior wall asbestos removal work. The Water Clean method does not require protection during construction as it is Level 3 compliant, but there are regions where protection is mandatory. The Water Clean protection system can be tightly and securely applied without gaps using a unique heat-shrink sheet, preventing the sheet from peeling or lifting due to wind, unlike traditional adhesive tape protection. It can wrap around the entire building, significantly shortening construction time, making it ideal for isolation protection and exterior wall protection work.

"Water Tank Lining (Reservoir Lining)" is a construction method used primarily for the internal lining (corrosion and waterproofing) of concrete tanks (such as PC tanks and RC tanks) to protect the structure over the long term. As the seismic retrofitting of water supply facilities is promoted to secure lifelines, internal lining plays a very important role in achieving the same objectives of securing water and preventing leaks. The balance between elongation and strength of waterproofing and anti-corrosion materials is a crucial factor, and in recent years, there has been increasing attention on high-strength, elongation-type polyurea resins over rigid coatings like epoxy, particularly from the perspective of preventing leakage accidents caused by earthquake damage. [Types of Construction] ■ Ultra-fast curing spray lining (urethane, polyurea) ■ Epoxy lining ■ Reinforced plastic lining (FRP, vinyl ester) ■ Mortar protection method *For more details, please refer to the related link page or feel free to contact us.

We will introduce the differences between the "Adhesive Method" and the "Insulation Method" for waterproofing work. The "Adhesive Method" is a technique that completely adheres the waterproof layer to the substrate, offering advantages such as relatively quick construction time and high cost performance. The "Insulation Method" is a technique that does not adhere the waterproof layer to the substrate (it floats), allowing the waterproof layer to be unaffected by the substrate, resulting in long-lasting durability. Our company proposes methods that suit your building and structure, ensuring long-lasting reliability. Please feel free to consult us. 【Adhesive Method】 ■ Advantages - High cost performance - Relatively quick construction time - Walkable and capable of heavy foot traffic (depending on the method) ■ Disadvantages - Since the waterproof layer is adhered to the substrate, it is affected by moisture contained in the substrate - There may be occurrences of cracks or blisters in the waterproof layer *For more details, please refer to the related link page or feel free to contact us.

The non-slip treatment of floors using shot blasting is a method that increases friction and prevents slipping by creating a textured surface on the flooring material. Many conventional processing methods primarily involved applying a non-slip coating to slippery areas; however, these methods have several issues, such as changing the existing design, reduced non-slip effectiveness when wet, deterioration and peeling of the coating, occurrence of lifting, and decreased non-slip performance due to aggregate loss. In contrast, the non-slip treatment using shot blasting is a construction method that maintains the existing design while ensuring that there is no peeling or reduction in non-slip performance over time. This method is particularly effective in high-traffic areas such as parking lots, gas stations, and walkways.
