fischer’s UltraCut FBS II stainless steel concrete screws and FIS EM Plus injection mortar ensure stable connections and efficient installation at the ACTV landing stage ‘San Zaccaria Danieli’ in the Italian city of Venice.

The new ‘San Zaccaria Danieli’ landing stage in Venice is a central landing stage for the vaporetti – the city's local water buses (ACTV). It connects the most important public transport lines on the water and is just a few steps away from St. Mark's Square. Thousands of passengers arrive and depart here every day – under extreme environmental conditions: salty air, splashing water, changing water levels and confined spaces. For the fastening technology, this means the highest demands on corrosion resistance, load-bearing capacity and installation speed. 

To meet these challenges, the project participants opted for two high-performance solutions, namely the fischer UltraCut FBS II 8–10 SK R stainless steel concrete screw and the fischer FIS EM Plus injection mortar. Both products complement each other perfectly and were used specifically for different tasks at the pier. The UltraCut FBS II fixes the load-bearing wooden beams of the jetty directly to the concrete beams. Its special thread geometry ensures powerful anchoring, while the flat countersunk head shape allows flush support. The expansion-free direct screw connection without drill hole cleaning saves valuable time and allows for minimal edge distances – a decisive advantage in confined spaces and under tight deadlines.

The fischer FIS EM Plus epoxy resin mortar is used wherever maximum loads and variable embedding depths are required, for example when fastening steel brackets and connecting elements that connect the supporting structure of the pontoon to the jetties. The epoxy resin mortar is approved for cracked concrete and seismic performance categories C1 and C2 and offers a service life of up to 100 years in accordance with the European Technical Assessment (ETA). Its high chemical resistance, particularly to weathering and moisture, makes it the ideal choice for the maritime environment of the lagoon and ensures strong, durable connections that reliably transfer loads to the supporting structure. Thanks to its assessment (ETA) for use in water-filled boreholes, it is ideally suited for use in difficult, wet conditions and has already proven itself successfully in underwater installations (ICC approval).

"In Venice in particular, extreme boundary conditions meet the highest requirements for safety. With UltraCut FBS II, we achieve fast, spread-pressure-free screw connections, while FIS EM Plus offers maximum load reserves. This results in a technically sound and economical solution for the new ACTV pier," emphasises Mario Allasia, technical sales representative at the Italian subsidiary of the fischer Group of Companies and project manager for fischer.

In addition to high-performance products, fischer relied on direct technical support on site during the construction of the vaporetto pier. fischer experts accompanied the execution of the project from the design and product selection to load testing on the construction site.

The fact that the fastening technology of the fischer Group of Companies is able to meet the special requirements of the lagoon has already been demonstrated elsewhere in Venice – for example, on the glass protective wall at St. Mark's Basilica and on the historic Procuratie. With the new landing stage, fischer is now making a further contribution to safe mobility in a city that lives from water like no other – and whose future is closely linked to the balance between tradition, technology and the tides of the lagoon.
