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.

Uses:

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

Features & Benefits:

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
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
