Injection mortar FIS EM Plus

The powerful injection mortar for rebar connections and cracked concrete

The fischer injection mortar FIS EM Plus is a high-quality epoxy mortar for top load-bearing capacity in cracked and non-cracked concrete and for seismic applications in performance categories C1 and C2. It is suitable for fixations of shear connectors for concrete layers, tall shelvings, and heavy steel constructions both inside and outside. The injection mortar is processed with the approved system components fischer threaded rod FIS A with variable anchorage depths and fischer internal threaded anchor RG M I as well as with reinforcement bars. The epoxy mortar is ideally suited for rebar connections that are installed with a large drill hole diameter and a high anchorage depth. It can also be used for diamond-drilled and water-filled drill holes.

Product Description

  • The optimised formulation of the epoxy mortar FIS EM Plus leads to improved load values in cracked and non-cracked concrete.
  • The ETA assessment guarantees a service life of 100 years. The IEA expert report even confirms a working life up to 120 years and thus underlines the reliability and durability of the FIS EM Plus.
  • The mortar can be used for rebar connections from diameter 8 to 40 mm.
  • With the threaded rod FIS A, the loads to be applied can be designed variably by selecting the anchorage depth.
  • Temporary and detachable fixing points are possible with the internal threaded anchor RG M I.
  • For practical use on the building site, FIS EM Plus can be processed at low temperatures down to -5° C.
  • The mortar is approved for diamond-drilled and water-filled drill holes as well as seismic applications of performance categories C1, C2 and thus offers safety under extreme conditions.

Assembly Instruction

  • The epoxy mortar FIS EM Plus combined with the FIS A threaded rod, is suitable for pre-positioned and push-through installation and with the internal threaded anchor RG M I for pre-positioned installation.
  • Resin and hardener are stored in two separate chambers and are not mixed and activated until extrusion through the injection capsule in the static mixer.
  • The mortar is injected bubble-free from the drill hole base.
  • The mortar bonds the entire surface of the anchor with the drill hole wall and seals off the drill hole.
  • The anchor is set manually by lightly rotating it until it reaches the drill hole base.
  • During push-through installation, the annular gap between the anchor rod and attachment is filled with FIS EM Plus.
