ECMAGROUT PU G 820
TWO COMPONENT, LOW VISCOUS, HYDROPHILIC, WATER REACTIVE, POLYURETHANE INJECTION SYSTEM TO BE USED AS ACTIVE WATER STOP FORMING AN ELASTIC GEL
ECMAGROUT PU G 820 is a two component, hydrophilic, 100% MDI based, solvent and phthalate free, polyurethane injection system which acts as an active water stop system by producing an elastic gel.
Mixing ratio 1:1 in volume ECMAGROUT PU G 820 has a special characteristic that the reaction time will be between 15-45 seconds independent from the amount of water present in the structure.Advantages
• Deeper penetration to fine cracks due to exceptional low viscosity • The cured material remains flexible • Suitable for hot and cold climates • Good adhesion to the substrate • Can withstand high hydrostatic pressures • The cured material is stable after curing • A pneumatic 2 or 3 component injection pumps should be used • The reaction time is almost independent from the amount of water to a maximum ratio G 820 to water <1:10 in the structure • Suitable for applications where fluctuating groundwater levels are encountered. • 100% MDI based and no TDI in it. • The cured material is non toxic • The system is suitable for use in contact with potable water
Uses
• A liquid but solidifying gel membrane applied to the positive side of a concrete structure from the negative side. (curtain grouting) • A vertical barrier to fill voids /joints in masonry walls • Preventative or remedial water proofing of structures. • Shutting off heavy water leakages • Repairing expansion joints • Seal off wet, moist and water containing structures • For sewer repair and manhole repair, manhole etc. • Consolidation of loose or unstable soil
