Overview
Full system delivering lower installed cost, reduced cycle times and superior performance.
TYTRO® is a comprehensive admixture system to reduce shotcrete installed costs, minimize excavation downtime and enhance performance. The system consists of macro fibers and admixtures designed to faster achieve early strength, enhance bond to rock substrate and between layers and deliver high-performance, high-quality shotcrete with minimum rebound and dust.
Shotcrete practitioners and producers stand to gain major savings on material and installation costs by incorporating the TYTRO® shotcrete system. Users can optimize mix cost, minimize rebound and accelerate cycle times to boost output while achieving desired technical performance and meeting the highest safety standards.
