Confirmed to meet quality standards through official test results! Reliable construction techniques and a wealth of experience.
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
