Universal injection mortar for a wide range of applications. Approved for concrete, masonry, seismic, fire protection, and post-installed rebar connections.

Injection mortar UPM44

The two-component vinylesterhybrid chemical anchor injection system UPM 44 is a professional fastening system designed for particularly high loads in all relevant building materials. When used with anchor rods UPM-A/ASTA or internal threaded anchors UPM-I/IST, UPM 44 boasts a comprehensive approval package for chemical fixings in perforated brick, solid brick, concrete, and aerated concrete. Moreover, this injection mortar stands out due to its multitude of approved system components and its approval for reinforcement connections.

Advantages

Product

Comprehensive approval package: ETA concrete approval option 1, masonry, retroactive reinforcement connection, seismic and fire protection testing
High loads: Universal hybrid mortar with high load-bearing capacity thanks to optimised mortar formula
Carefree working: Suitable for use in water-filled drill holes
Efficient in perforated bricks: The sieve sleeve for use in perforated brick masonry bridges the plaster and minimises mortar consumption
Fastening close to edges: The expansion pressure-free fastening allows for small edge and centre distances and prevents installation damage in the edge area
Flexible working: By changing the static mixer, opened cartridges can be reused

Functioning

Function: In the injection cartridges, resin and hardener are stored separately and only mixed into mortar when squeezed through the static mixer. The static mixer ensures bubble-free mixing of the two components and protects the injection mortar from curing inside the cartridge. The extruded injection mortar completely surrounds the anchor, bonds with the borehole wall, and seals the borehole. In perforated masonry and when using the perforated sleeve UPM-SH, the grid structure of the sieve sleeve ensures even distribution of the mortar in the borehole and prevents mortar loss in the cavity. Additionally, non-load-bearing layers can be bridged. For multiple uses of an injection mortar, the static mixer is not to be removed after the first use. The mortar cures inside the static mixer, which is only replaced for the next use

Installation: The Upat injection mortar UPM 44 is used with Upat anchor rods in pre-positioned or push through installation and with Upat internal thread anchors in pre-positioned installation. Set borehole, clean borehole. Use the perforated slee UPM-SH in perforated masonry. Fill borehole. Insert anchor rod. Screw on attachment - done. The anchor is pressed into the filled borehole by hand with gentle rotating movements. The temperature in the building material must not fall below the specified minimum value during the curing of the mortar. Minimum cartridge temperature +5°C. When setting the anchor rod in perforated masonry, it is recommended to use the Upat perforated sleeve UPM-SH

Tools: Drill, drill machine, blow-out pump (UPM AB), cleaning brush (UP BS), dispenser gun (UPM DM P/AM), torque wrench
