Hidden fastening allows for spectacular façades 16 August 2018

55,000 KEIL undercut KH anchors have been used for the safe fixing of a large sized, long-lasting, ceramic tile façade for the new building of Frankfurt’s School of Finance & Management – providing a permanent connection with a Systea® supporting construction.

KEIL’s undercut anchor is the supporting pillar on the back side of the tile. It is a positive locking, purely mechanical fixing, which is free from expansion pressure and acts in the background. KEIL Befestigungstechnik manufactures these anchors from high-quality stainless steel in Engelskirchen in the area of Bergisches Land.

Due to the invisible fixing on the back side, the colours of the ceramic tiles can come into their own – with lasting effect. As the tile is not penetrated by clamps, screws or rivets, no dirt will gather underneath them and the tile will remain clean.

As far as constructional supervision is concerned, the tile fixing is subject to authorisation. Apart from a multitude of national and European authorisations or valuations respectively, there is also an ETA (European Technical Assessment) for MOSA porcelain stoneware. Thus, for the façade of the School of Finance in Frankfurt, the ETA – (09/0348) KEIL undercut anchor for Royal MOSA porcelain stoneware regulates how even the 36m high façade could be safely built.

As a purely mechanical fixing, the KEIL undercut anchors could be mounted in Frankfurt without any trouble and regardless of the weather, as neither temperature nor humidity impact the high bearing capacity of the fixings.
