Viaduct Blackbox for Repair Mortar
Viaduct Blackbox for Repair Mortar is a pre-engineered formulation system designed to help manufacturers produce high-performance, polymer-modified repair mortar for structural and non-structural concrete repairs. Built on a controlled formulation approach, it ensures strong bonding, low shrinkage, and durable repair performance across a wide range of repair conditions.
Just open the Blackbox, mix it with the prescribed raw materials in the recommended ratio, and the complete repair mortar formulation is ready for production. No formulation trials. No dependency on site improvisation. No R&D investment.
This engineered system delivers excellent adhesion to old concrete, improved crack resistance, and controlled setting—allowing manufacturers to offer a reliable repair mortar for patch repairs, spalled concrete, honeycombs, edges, and surface defects. Easy to manufacture, simple to control, and trusted in performance, Viaduct Blackbox is the smart way to produce repair mortar with confidence.
