The "Concrete Keeper Series" is an inorganic lithium-based mixed type concrete impregnation material. It features "Concrete Keeper," which primarily consists of lithium silicate combined with silane, and the topcoat material "Concrete Keeper neo." It is suitable for concrete repair and deterioration prevention. 【Features】 ■ Inorganic lithium-based mixed type ■ Concrete repair and deterioration prevention ■ Two main components that block concrete deterioration in a double action *For more details, please refer to the PDF document or feel free to contact us.

"Super Shield" is a high-performance concrete waterproofing and protective material in a colloidal solution type, primarily composed of sodium silicate and potassium silicate. It offers new technology for extending the lifespan of concrete while reducing maintenance costs, all while protecting the natural environment. Compared to water-soluble concrete protective materials and water-repellent concrete protective materials based on silicates, it has excellent durability and, through high-function self-repair, continues to protect concrete from various forms of deterioration for a long time, firmly and stably. 【Performance Characteristics】 ■ Suppression of carbonation ■ Suppression of salt damage ■ Suppression of freeze damage ■ Suppression of rebar corrosion ■ Suppression of alkali-aggregate reaction ■ NETIS Registration No. QS-150019-VE *For more details, please refer to the PDF document or feel free to contact us.

"Re-Flex" is a concrete night reflective paint that enhances driver visibility and improves driving safety by being applied to concrete surfaces. It comes in a color that does not compromise the appearance of concrete and reflects light brightly in dark places and at night. It reflects light only in the direction of the light source, even when illuminated from various angles (retroreflective). After easily cleaning existing concrete, it can be painted without special surface preparation. Additionally, it does not require a primer or topcoat, and retains a strong film after air drying at room temperature. 【Features】 - A color that does not compromise the appearance of concrete - Brightly reflects light in dark places and at night - Does not require a primer or topcoat, retaining a strong film after air drying at room temperature - Coats the concrete surface with a special resin emulsion - Blocks deterioration factors *For more details, please refer to the PDF document or feel free to contact us.

The "Stamp Method" involves coloring the surface of concrete with a color hardener after pouring the ready-mixed concrete, and before the concrete hardens, pressing a "pattern mat" with natural stone, brick, or wood patterns to create designs. By embossing, a textured pattern is formed on the concrete surface, resulting in a natural finish. Additionally, because it is integrated with the concrete, it does not peel or become uneven, nor does it allow weeds to grow from the joints, making it highly durable. 【Features】 ■ Finishes with a natural texture ■ Highly durable due to integration with concrete ■ Natural shading and three-dimensional effect from the release powder ■ A lineup of 12 different pattern variations ■ Resistant to tire marks and has dirt-repellent properties *For more details, please refer to the PDF document or feel free to contact us.

The "IPH method" replaces the air present inside the concrete and the injected resin, allowing the resin to diffuse radially from the drilled holes, thereby filling even the finest cracks at the ends. This method not only enhances the adhesion strength between rebar and concrete but also provides a high anti-corrosion effect, leading to improved durability. It has received technical evaluation from the Japan Society of Civil Engineers. Moreover, structures constructed using this method can extend the intervals between subsequent repairs. Since the deteriorated areas are repaired and injected without being chipped away, the amount of demolition waste is reduced, resulting in cost savings. 【Features】 ■ High-density filling ■ Rebar anti-corrosion and neutralization suppression ■ Strength recovery and durability improvement ■ Enhanced economic efficiency and environmental measures *For more details, please download the PDF or feel free to contact us.

The "Galva Shield Method" is a special product that wraps zinc in a special mortar and utilizes the potential difference of metals to prevent rusting of rebar. It can be installed in both maintenance and repair of concrete structures (such as salt damage, carbonation, and macrocell corrosion) as well as new structures, offering a wide variety of options based on LCC and the presence of inherent salts. Additionally, the "Renderock Series" is used as a cross-section repair material. 【Features】 ■ NETIS Registration No. CB-020037-VE ■ Utilizes the potential difference of metals to prevent rusting of rebar ■ Can be installed in both maintenance and repair of concrete structures and new structures ■ A wide variety of options available based on LCC and the presence of inherent salts *For more details, please refer to the PDF materials or feel free to contact us.
