Fischer FIS EM Plus 390 S Epoxy Mortar

High-Performance Injection Mortar for Heavy Load Anchoring in Cracked & Non-Cracked Concrete

Product Overview

The Fischer FIS EM Plus 390 S is a premium, two-component epoxy injection mortar engineered for secure anchoring in both cracked and non-cracked concrete. With ETA approvals and exceptional load-bearing capacity, it is ideal for structural reinforcements, rebar connections, seismic retrofits, heavy steel anchoring, and demanding construction environments.

Why Choose FIS EM Plus 390 S?

• Optimized resin formulation for enhanced load values in both cracked and non-cracked concrete.

• Approved for diamond-drilled and water-filled holes, ensuring versatility on-site.

• Validated for seismic zones (performance categories C1 and C2) for dynamic load resilience.

• Reliable performance at low temperatures (down to –5 °C), suitable for cold weather installations.

• ETA-assessed service life of 100 years, extendable to 120 years via expert report.

• Supports rebar diameters from 8 mm to 40 mm for a wide range of structural needs.

Applications

• Post-installed rebar connections in existing concrete

• Shear connectors and concrete layer jointers

• Heavy steel structures, rail fixings, and tall shelving systems

• Seismic reinforcement and retrofitting

• Anchorings in water-filled or diamond-drilled holes

• Temporary or removable fixings (with internal threaded anchors)

• Wood-concrete or wood-steel connections (approved for glued laminated timber)

How It Works

FIS EM Plus 390 S is supplied as a dual-component cartridge (resin + hardener). Components remain separate until extrusion through the FIS MR Plus static mixer, ensuring perfect mixing at the point of use.

The mortar is injected bubble-free from the base of the drilled hole, fully bonding the anchor or rebar to the concrete wall and sealing the bore. In push-through installations, the annular gap between the anchor and fixture is filled with the epoxy mortar.

Compatible anchors include Fischer FIS A threaded rods or internal threaded anchor RG M I, allowing flexible embedment depth and load transfer.

Benefits & Advantages

• Superior adhesion and load performance, even in cracked concrete

• Durable under environmental and structural stresses

• Works under wet or flooded conditions — approved for water-filled holes

• Suitable for seismic zones (C1, C2)

• Usable at low temperatures (down to –5 °C)

• ETA-backed service life: 100 years (up to 120 years via expert report)

• Simplified installation with pre-measured cartridges and static mixer

• Compatible with various anchor rods and systems

Installation Guidelines (Brief)

1. Drill hole to specification (diameter and depth)

2. Clean thoroughly (blow, brush, or vacuum)

3. Insert static mixer and inject mortar from the bottom

4. Insert anchor or rebar with slight rotation

5. Allow curing per technical datasheet

6. Apply design loads after full cure
