ECMAGROUT PU F 260

TWO COMPONENT, HYDROPHILIC, POLYURETHANE INJECTION SYSTEM
TO STOP WATER LEAKAGES, FORMING AN ELASTIC GEL EXPANDING
AFTER CURING.

ECMAGROUT PU F 260 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 or 2:1 in volume

ECMAGROUT PU F 260 has special characteristics that the reaction time will be
between 15 – 45 seconds independent from the amount of water present in the
structure and that the gel expands after curing.

Advantages

• Deeper penetration to fine cracks due to low exceptional low viscosity
• The cured material remains flexible
• Suitable for hot and cold climates
• Good adhesion to the substrate
• Can withstands 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 F 260 to water < 1:10 in the structure
• The formed gel will expand after curing and fixes itself into 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
