The "Reinforcement Method" involves applying a crystal lining material, then attaching carbon fiber or glass cloth (reinforcement fiber sheet), and finishing by applying the crystal lining material again on top. By combining with carbon fiber or glass cloth, it enables corrosion protection while simultaneously providing structural reinforcement (such as crack confinement effects for unreinforced structures, structural reinforcement for rusted rebar areas, and seismic reinforcement). The "Manhole Joint Displacement Prevention Reinforcement" performed in combination with carbon fiber has a proven track record of earthquake resistance, contributing to disaster reduction while achieving cost savings. 【Features】 ■ Corrosion protection ■ Crack confinement effects for unreinforced structures ■ Structural reinforcement for rusted rebar areas ■ Seismic reinforcement ■ Resistance to lateral shaking due to the use of bidirectional carbon fiber *For more details, please refer to the PDF document or feel free to contact us.

The "Reinforced Water Stopping Method" involves V-cutting along cracks and joints in areas where water infiltrates, applying a water-resistant surface using quick-setting cement mixed with special water-based epoxy resin, and then coating it with crystal lining material and layering glass cloth to finish, creating a strong adhesive lining layer. This method can be implemented in high-humidity environments and possesses strong adhesive properties, allowing it to maintain water stopping effectiveness over the long term compared to conventional methods. 【Features】 ■ Can be constructed in high-humidity environments ■ Strong adhesive strength ■ Capable of maintaining water stopping effectiveness over the long term ■ Certification for water pressure resistance and water stopping properties ■ Obtained "Construction Technology Review Certification" *For more details, please refer to the PDF materials or feel free to contact us.

The "Anti-Corrosion Lining Method" is a technique where a crystal lining material is applied and then topped with a crystal lining topcoat. It can also be implemented in construction environments (high humidity, wet conditions) during repairs of existing pipeline facilities (manholes, conduits, etc.). It complies with the quality standards of the Japan Sewerage Agency's "Manual for Corrosion Control Technology and Anti-Corrosion Technology for Sewer Concrete Structures," specifically for the coating-type lining methods (Type C) and (Type D). 【C Type Quality Standard Test Results (Excerpt)】 ■ Appearance of the coating: No wrinkles, unevenness, peeling, or cracking observed. ■ Adhesion to concrete: - Standard condition: 2.7 N/mm² - Water absorption condition: 2.6 N/mm² ■ Acid resistance: No blistering, cracking, softening, or leaching observed in the coating. ■ Depth of sulfur intrusion: - 4% relative to the design thickness - Intrusion depth: 38 μm *For more details, please refer to the PDF document or feel free to contact us.

The "Manhole Seismic Reinforcement Method" is a technique that addresses the seismic reinforcement of unreinforced manholes (primarily circular) using a seismic reinforcement system (seismic calculations) and carbon fiber (seismic reinforcement). It achieves significant cost reductions and can also be used in conjunction with anti-corrosion methods (coating type). This method complies with the "Guidelines and Explanations for Seismic Measures for Sewer Facilities 2014 Edition (Japan Sewer Association)." 【Features】 ■ Significant cost reduction ■ Adoption of a seismic reinforcement system (seismic calculations) and carbon fiber (seismic reinforcement) ■ Applicable to seismic reinforcement of unreinforced manholes (primarily circular) *For more details, please refer to the PDF materials or feel free to contact us.

The "Crystal Lining Method Catalog" is a catalog introducing the methods of the Crystal Lining Method Association, which mainly conducts aging countermeasure projects for sewer facilities. It presents methods that demonstrate excellent performance in corrosion prevention and maintenance of concrete structures. The method involves applying a solvent-free epoxy resin mortar with anti-corrosive properties to concrete structures for water stopping (adhesive reinforcement type water stopping), corrosion prevention (coating type lining), reinforcement (reinforcement lining), and seismic reinforcement of manholes, using a manual construction method that does not involve machinery.
