    Sprayed Concrete / Shotcrete in Australia

    Advanced systems for high-performance sprayed concrete.

    High-quality, durable shotcrete (sprayed concrete) has become a vital component of ground support and stabilisation in tunnelling and mining. With shotcrete’s relatively low price, wet mix sprayed tunnel linings create state-of-the-art, monolithic/composite structures with a substantial reduction in cost and time. This also lowers health risks, increasing worker safety and reducing the environmental impact versus conventional concrete placement.

    What Makes Master Builders Solutions Shotcrete Unique?

    Constantly striving to exceed customer needs and demands, our concrete admixture technologies​ enhance sprayed concrete's performance, hydration control and viscosity.

    MasterRoc SA

    Fast-setting alkali-free accelerator series (MasterRoc SA) produces sprayed concrete with early strength development and long-term strength. The combined use of structural reinforcing fibres has greatly improved the load absorption performance, decreasing residual crack propagation and increasing long-term durability for permanent support.
    We offer a multitude of chloride-free liquid admixtures to improve concrete's plasticity and hardened properties.

    MasterRoc HCA 20 

    MasterRoc HCA is a cement hydration control system for wet and dry sprayed concrete applications. The admixture is capable of maintaining a pot life for up to 72 hours, allowing for total and accurate flexibility of site logistics.

    MasterRoc MS 699 

    By adding microsilica (MasterRoc MS), we reduce permeability to increase the density and long-term strength and durability performance of the sprayed concrete in its hardened state. Microsilica also can improve the pumpability and workability of the sprayed concrete system in its fresh state.

    With an abundance of shotcrete concrete solutions for different applications, Master Builders Solutions is her to help. To learn more about more solutions, utilities, variations, and more, speak with one of our experienced specialists today.

    MasterFiber 141

    MasterFiber 141​ is a fibre extruded from polyolefine polymers and formed into a embossed fibre that can be used in concrete mixes for both spray and cast in-situ applications. The inclusion of fibres in a concrete mix will contribute to improving the durability of concrete by increased crack propagation resistance and by its energy absorption characteristics.​
