ARDEX RA 146 Thixotropic Epoxy Concrete Repair - 470mL

ARDEX RA 146 Thixotropic Structural Epoxy Adhesive

ARDEX RA 146 is a professional-grade, thixotropic structural epoxy gel engineered for high-performance concrete repair. This advanced system is specifically designed for injecting medium-sized cracks (6mm to 10mm). Its unique thixotropic property ensures it flows easily under injection pressure but sets instantly when pressure is released, making it the premier solution for vertical, overhead, and blind-side applications where preventing material drainage is critical.

Structural Integrity Restoration

Formulated to restore cracked concrete structures to their original monolithic strength, ARDEX RA 146 provides a permanent seal for internal and external slabs, walls, and columns. For a comprehensive repair system, use in conjunction with injection ports and a capping paste such as ARDEX RA 88. Its superior bonding ensures long-term resistance to environmental stressors and mechanical loads.
