"Deep Insilan" is a silane-siloxane based impregnation material that forms a high-density water-repellent layer by penetrating the concrete surface, effectively preventing the long-term intrusion of external deterioration factors through high water repellency. The water-repellent layer blocks moisture and chloride ions from the outside, while allowing water vapor from within the concrete to pass through. Additionally, this product causes minimal surface changes after application, maintaining the texture of the material over a long period. Please feel free to contact us if you have any inquiries. 【Benefits】 ■ Extended lifespan ■ Suppression of deterioration progression ■ Surface protection ■ Increased durability ■ Prevention of deterioration factor intrusion, etc. *For more details, please download the PDF or contact us.

• Coating film waterproofing material/permeable waterproofing material

"SGSKY" is a water-based, VOC-free surface protection material for concrete products, bricks, and ceramic materials that is environmentally friendly. It suppresses the growth of microorganisms such as mold and algae, as well as the adhesion of blackening on bricks and efflorescence from joints. It provides excellent water repellency and oil repellency to porous inorganic materials, resulting in minimal change in appearance after application, and the texture of the material is maintained over a long period. 【Features】 ■ Minimal change in appearance after application, with the texture of the material maintained over a long period ■ Provides excellent water repellency and oil repellency to porous inorganic materials ■ Suppresses the growth of microorganisms such as mold and algae ■ Maintains surface dirt resistance over a long period and makes cleaning easier ■ Suppresses the adhesion of blackening on bricks and efflorescence from joints *For more details, please refer to the PDF document or feel free to contact us.

The "Bridge Manhole Cover Holder" is a device that prevents the manhole cover from bouncing up. Due to its structure that does not block the drinking mouth of the manhole, it ensures drainage without clogging, and because it fixes the lower manhole and the eye plate, it can also prevent the upper manhole from scattering at the same time. For catch basins that are outside the scope of this product, we will manufacture compatible items from one piece based on our unique database, in conjunction with drawings and survey data (including contracts). Please feel free to contact us. 【Features】 ■ Good workability ■ Ensured safety ■ Excellent maintenance performance ■ No obstruction of water flow ■ Capable of handling special cases *For more details, please refer to the PDF materials or feel free to contact us.

• Grating

"KT-N" is a lithium nitrite-based rust prevention impregnation material. Nitrite ions have the effect of regenerating the passive film on the surface of rebar, while lithium ions help suppress the expansion of alkaline silica gel. By supplying this product through injection methods, cross-section repair methods, and impregnation methods, the passive film around the rebar is regenerated, and it is expected to continue to suppress the corrosion of the rebar. Additionally, by impregnating the silicate-based impregnation material "KC Guard α" after the injection and impregnation of this product, the measures for extending the lifespan of concrete structures will be further ensured. 【Features】 ■ Regeneration and protection of rebar passive film ■ Suppression of macrocell corrosion occurrence ■ Alkaline addition ■ Suppression of rebar corrosion in concrete structures (ASR measures) ■ Improvement of durability of concrete structures, prevention of aging, and extension of lifespan *For more details, please refer to the PDF materials or feel free to contact us.

We would like to introduce the 'SK-System', a method for extending the lifespan of concrete structures, preventing deterioration, and addressing salt damage, conducted by Kobori Sangyo. This method utilizes two types of concrete surface impregnation materials with different functions, maximizing their respective functional characteristics to protect the surface of the concrete and suppress the progression of structural deterioration, thereby extending its lifespan. There is minimal change in appearance after application, and the texture of the material is maintained over the long term. 【Features】 ■ Extension of the lifespan of concrete structures ■ Suppression of rebar corrosion ■ Minimal change in appearance after application, with long-term retention of material texture ■ Suppression of deterioration progression in concrete structures, surface protection, improvement of durability, and preventive maintenance (suppression of the intrusion of deterioration factors) *For more details, please refer to the PDF document or feel free to contact us.

This product can be lifted almost vertically, preventing damage or breakage to the grating rails compared to traditional opening and closing methods using bars. We offer attachments for standard (normal) and fine mesh, compatible with all grating thicknesses (h). In the unlikely event that an attachment is damaged, it can be replaced, leading to cost savings. 【Features】 ■ Capable of opening and closing various types of grating ■ Can lift grating almost vertically when using two units as a set ■ Significantly reduces the risk of damage to frames and grating when using bars ■ The main body is constructed from special steel for durability ■ The attachment can rotate 360° horizontally, allowing alignment with the direction of the rails (main components) *For more details, please refer to the PDF document or feel free to contact us.

"TNLOCK" is a nut and washer that demonstrates excellent effectiveness in safety, workability, and cost efficiency. It exhibits anti-loosening effects against severe vibrations due to its unique wedge action. Since it can be repeatedly removed and reattached, it contributes to cost reduction. It significantly helps prevent loosening and accidents due to tampering in outdoor structures, transportation, vehicles, residential equipment, and playgrounds. 【Features】 ■ Exhibits anti-loosening effects against severe vibrations due to its unique wedge action ■ Can be tightened using standard tools ■ Can be repeatedly removed and reattached, leading to cost reduction ■ Requires a dedicated socket for removal, making it suitable for structures that need tampering and theft prevention measures *For more details, please refer to the PDF document or feel free to contact us.

"KC Guard α" is a concrete surface impregnation material that, by simply spraying it on the surface of concrete, densifies the surface structure and provides high durability. It enables the enhancement of the durability of concrete structures and allows for a transition from traditional maintenance or remedial approaches to a crisis management approach. Additionally, it can significantly improve the life cycle cost (LCC) during the service life of the structure. 【Features】 ■ Salt damage suppression ■ Carbonation prevention ■ Waterproofing ■ Appearance retention ■ Easy application method *For more details, please refer to the catalog or feel free to contact us.
