New assessment for fischer FIS EM Plus 21 November 2019

The fischer injection mortar FIS EM Plus permanently and safely transfers heavy loads into concrete even under the most extreme of conditions. It has demonstrated its capabilities on record breaking constructions such as the world’s longest sea crossing, China’s ‘Hong Kong–Zhuhai–Macau Bridge’, and the ‘Statue of Unity’ in India, the world’s tallest statue.

A new assessment has now certified that the FIS EM Plus has a lifespan of 120 years, which is a unique selling feature on the market. The FIS EM Plus is fischer’s highly reliable bonded anchor for high load-bearing capacity in concrete (C20/25 to C50/60). The injection mortar even provides a reliable hold in earthquake prone areas and has been approved for category C1 and C2 seismic applications and categories A to F in accordance with the ICC-ES. It is also a safe choice for water filled drill holes and in case of fire (R240 fire resistance assessment).

The FIS EM Plus has two European Technical Assessments (ETA) that cover fixings in cracked concrete (Option 1) and post-installed rebar connections. ETA – 17/0979 recently extended the working life for fixings in concrete from 50 to 100 years. fischer is therefore among the first in the industry to prove this feature in the assessment.

The Stuttgart engineering firm IEA takes things one step further. This approved and notified monitoring and certification centre has certified in an anchoring assessment that the fischer FIS EM Plus has a working life of 120 years. It is the first injection mortar to have ever been awarded such durability. This is a clear advantage for constructions that rely upon a long working life, such as tunnels, reservoir dams and other infrastructure projects.

The FIS EM Plus is processed with approved system components such as the fischer threaded rod FIS A – with variable anchorage depths – that can be adapted to the existing load, or the fischer internal threaded anchor RG M I, which is also suitable for temporary and removable fixings. The use of the FIS EM Plus in combination with the fischer rebar anchor FRA is also covered by the ETA. The injection mortar can be used for rebar connections between 8mm and 40mm and enables a bonding depth of up to 2,000mm. Together with the Concrete-Concrete Shear Connector FCC the injection mortar is ideal for the restoration and reinforcement of buildings, bridges and other structures and constructions.

As an all-rounder for various building site conditions, the epoxy mortar can also be processed at low temperatures down to -5°C. The FIS EM Plus has also been approved for water filled drill holes. Its optimised formula results in improved load values in concrete, which requires fewer fixing points. The optimised axial and edge spaces enable flexible calculations and fixings placed close to the edge.

The FIS EM Plus is also easy to use. There is no need to clean the drill hole when using a hollow drill. The injection mortar can also be used in diamond cut drill holes in concrete, without requiring additional roughing up or associated procedures and tools, while delivering an optimum performance.
