    ​MasterFlow 928 - Cementitious high strength non-shrink precision grout

    How does MasterFlow 928 work?

    MasterFlow 928 is a non-shrink, natural aggregate precision grout with excellent high early and ultimate strengths. It is specially formulated to provide extended working time even at high ambient temperatures when mixed and placed at any recommended consistency. MasterFlow 928 is normally placed at a flowable consistency to completely fill voids between 25mm and 100mm. Thicknesses greater than 100mm are possible with the addition of aggregate.

    Recommended uses:

    • Critical equipment baseplates, soleplates & columns;
    • Precast wall panels, beams, columns, structural building members and curtain walls;
    • Patching poured in place concrete structures, e.g. honeycombing, using preplaced aggregate techniques;underpinning;
    • Concrete repair applications where a form and pour material is required;
    • Applications requiring high early compressive strengths and high ultimate compressive strengths.

    What makes MasterFlow 928 a unique solution?

    MasterFlow 928 is a precision grout which with its double stage shrinkage resistance characteristics provides durable solution for crack free heavy duty cementitious grouting applications

    What are the features and benefits of MasterFlow 928?

    • High early strength – Ensures rapid commissioning of new equipment and structures.
    • High ultimate strength – Ensures permanence of the installation under static and moderate repetitive loads.
    • Flowable long life grout – Easy to grout intricate spaces normally inaccessible by conventional grouting technique.
    • Extended working time – Facilitates grouting of large or difficult placements in a single pour, often without the use of a pump.
    • Dense, non-shrink grout – Hardens free of bleeding, settlement and drying shrinkage, ensuring tight contact with all grouted surfaces.
    • Easy to use – Requires no special mixing equipment, it can be mixed in a standard concrete mixer or in a pail using a grout stirrer.
    • No added chloride – Does not add to chloride load of structure
