ECMAGROUT PU G 840
TWO COMPONENT, LOW VISCOUS, HYDROPHILIC, WATER REACTIVE, POLYURETHANE INJECTION SYSTEM WITH AN EXTENDED REACTION TIME AND FORMING AN ELASTIC GEL.
ECMAGROUT PU G 840 is a hydrophilic, two component, 100% MDI based, solvent and phthalate free, polyurethane injection system with an extended gel time forming an elastomeric gel. Mixing ratio 1:1 by volume ECMAGROUT PU G 840 has special characteristics that the reaction time will be between 20–25 minutes independent from the amount of water present in the structure.
• 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 • 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
• A liquid but solidifying gel membrane applied to the positive side of a concrete structure from the negative side. (curtain grouting) • Preventative or remedial water proofing of structures. • To be used in injection hoses • Seal off wet, moist and water containing structures • Consolidation of loose or unstable soil
