Water-based adhesion and application to concrete for corrosion protection using the "Crystal Lining Method."
Using a solvent-free epoxy resin mortar that cures in water, sewer facilities are repaired through manual construction. Applications include corrosion protection, water stopping, reinforcement, and seismic reinforcement of manholes.
This method involves applying a solvent-free epoxy resin mortar with anti-corrosive properties to concrete structures for water stopping (adhesive reinforcement type water stopping work), corrosion prevention (coating type lining work), reinforcement (reinforcement lining work), and seismic reinforcement of manholes, using manual labor without machinery. Although there are slight differences in the surface preparation methods and layering processes for each purpose, all methods utilize a crystal lining material that has the property of adhering and curing even underwater. 【Applications】 ● Water stopping, corrosion prevention, and reinforcement for sewer facilities (treatment plants, pipes, manholes, etc.) ● Seismic reinforcement of manholes ● Corrosion prevention for walls and floors in food factories ● Painting and repair of drinking water facilities (such as water storage tanks) ● Prevention of deterioration in reinforced concrete ● Use as a reinforcement material for concrete ● Other general civil engineering and construction applications

Company information
Since its establishment, our company has played a role in national construction, primarily focusing on the "ground improvement field" with our unique grouting method. Subsequently, in response to the changes in social infrastructure development, we have refined our technologies to adapt to the needs of the times and, at times, acquired new ones to expand our business scope. As a result, we have now established three main pillars: "ground improvement business," "slope disaster prevention business," and "pipeline business."
