​​​​​​​MasterRoc MP 355

Highly-reactive, two-component polyurethane injection resin

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​
