Today more than ever, environmental protection is our passion. It is essential to protect the environment, particularly our waterways as they are fundamental to human life and survival. Anchors in plants containing water polluting substances that are not fitted with two sealing levels must fulfil specialised requirements in accordance with the German Water Resources Law (WHG) and the Plant Regulations (AwSV).
These specialist applications require specially tested anchor systems. fischer offers a reliable solution for this application with injection mortar FIS EM Plus. The system is tested and has been issued a general construction technique permit by the Deutsche Institut für Bautechnik (DIBt) for various groups of media for liquid impermeable concrete (LI concrete).
For coated concrete fischer has verified, through an independently accredited testing institute and expert report, that the fixing system fulfils the WHG.
The general construction technique permit and the expert report of the anchors require that the users are trained.
Because of this, fischer offers comprehensive training for users and engineers – to ensure you are well-prepared.
To the fischer WHG Sets
When installing anchors in WHG sealed surfaces, a hole is drilled into the WHG surface, potentially reducing the seal at this location. However, the seal and resistance must be verified in the area of the anchors as well.
Now, fischer offers solutions for these applications that can be used to install anchors in WHG sealing surfaces according to the German Water Resources Law (WHG) and Plant Regulations (AwSV).
With the injection mortar FIS EM Plus, fischer has obtained the first general construction technique permit for WHG compliant anchors for applications in LI concrete. The system was comprehensively tested with materials in media list 4 of the DIBt.
With fischer, you are on the safe side for anchors in WHG sealing surfaces!

An anchor in LI concrete must be designed so that no liquid can penetrate through the anchor in the concrete. The drill hole can be constructed using hammer drilling or with a hollow drill bit. The drill hole depth must always be at least 50 mm less than the substrate thickness. The epoxy mortar FIS EM Plus, anchor rod FIS A / RG M or internal-threaded anchor RG MI and WHG marking are required for anchors in LI concrete. In general, the aBG requires anchor materials made of stainless steel for WHG applications.
The marking disc is an important part of the fischer WHG fixing system. It clearly and permanently indicates use of the correct system, and facilitates simple, reliable building approvals. It is mounted between the washer and attachment.
The seal is achieved by filling the annular gap between the anchor rod, attachment and base coating with FIS EM Plus mortar. The anchor solution in coated concrete includes epoxy mortar FIS EM Plus, the FIS A / RG M anchor rod or RG MI internal-threaded anchor and the WHG set. Sealing is tested for epoxy floor coatings.
The fischer WHG-Set is used for anchors in coated concrete. The WHG set is used to fill the annular gap with injection mortar FIS EM and seal it. The fixing point is labelled as a WHG compliant anchor. The epoxy mortar FIS EM Plus, anchor rod FIS A and the WHG set are required for anchors in coated concrete.
