    ​​​​​​​MasterRoc MP 355

    Highly-reactive, two-component polyurethane injection resin

    Formerly: MEYCO MP 355

    How does MasterRoc MP 355 work?

    MasterRoc MP 355 is a two-component, solvent-free polyurethane injection resin specifically designed for stopping rapid water flow and ground stabilization.

    Recommended uses:

    • Control of high volume water ingress
    • Stabilization of fractured rock, sands and gravels, and land-fill materials
    • Void filling
    • Repair of concrete structures

    What are the unique features of MasterRoc MP 355?

    • When in contact with water, the product forms a rigid foam. In the absence of water, the product reacts and forms a stiff, rubber-like material
    • Fast-reacting material where structural strength or rigidity is required

    What are the benefits of MasterRoc MP 355?

    • Reacts either with or without water. This is a significant safety advantage as the material will always be cured
    • Modification of the reaction can be achieved using an accelerator and a thixotropic agent, which are supplied separately to Component A
