Application

  • To stop small to medium water ingress in underground structures
  • Filling of voids containing water
  • Crack injection of above or below grade structures, including (but not limited to) water/wastewater tanks, storm pipes, manholes, culvert joints, dams, brickwork and natural stones, tunnel linings, concrete foundations, slab on ground, and bridge abutments.
  • Geotechnical applications

Description

MasterRoc MP 351 LV is a hydrophobic polyurethane resin designed to be injected into tight cracks. When mixed with the accelerator, MasterRoc MP 351 LV resin reacts with water or moisture to foam and cure to a closed-cell and flexible material that is resistant to most organic solvents, mild acids, alkali, petroleum, and micro-organisms.

What are the unique features of MasterRoc MP 351 LV?

  • Ultra-low viscosity
  • Fast reacting
  • Excellent bonding to a wide variety of surfaces (including wet, mineral, and metallic)
  • Superb elastic properties
  • Large foam volume with no shrinkage
  • Modification of the foaming action can be achieved by using an accelerator

What are the benefits of MasterRoc MP 351 LV?

  • Ideal for fine crack and fissure penetration
  • Highly effective in water stopping applications
  • Can accommodate considerable movements of construction components
  • Cost effective for stopping water ingress
  • Adjustable reaction time (by using the associated accelerator) provides application flexibility
