Water-reactive, hydrophobic polyurethane resin that forms a foam that does not absorb water; it is not affected by the lack of moisture - it does not shrink or swell. The duration of the gel product can be adjusted by adding the appropriate amount of Maxurethane Injection Flex CAT (MIFC) accelerator.

Features

• only requires single component injection equipment; reacts with running water and soil moisture
• low viscosity, even during injection, which ensures effective and deep penetration
• no shrinkage
• the stability of the chemical structure of the foam ensures its high durability, high mechanical resistance and the ability to withstand high water pressure
• environment friendly
• solvent free
• material easy to work with, and water does not dilute it
• high coefficient of expansion - up to 15 times

Application

• water shut-off in damaged, cracked concrete, concrete with many bubbles, sealing points and concrete expansion joints, brick structures, sewage tanks and drinking water tanks, sewers, manholes, tunnels, dams, - penetration pipes
• filling large cavities and cracks in stone and concrete structures
