Anchoring for extreme conditions 14 March 2016

During the construction of Milan Expo 2015, several Bossong SpA anchors were installed in the building sites of the various pavilions and common structures. Making it the perfect venue for the company to host a press conference focusing on ‘Italian know-how for anchoring in extreme conditions’.

Bossong is dedicated to providing the highest safety for extreme environments, which has led the company to carry out various tests with different installations and applications for chemical anchors in special situations.

In the field of seismic fixing with pure epoxy, Bossong has always considered the secure design of buildings as a priority and has obtained the European qualification of the EPOXY 21 chemical anchor in category C2. The product is suitable for structural and non-structural applications with all levels of seismic activity.

Another resin for extreme anchoring is V-PLUS vinylester for heavy loads.Two versions have been created for specific climate conditions. The first is the V-PLUS TROPICAL version, which is suitable for installation at very high temperatures, up to +50°C. The second is the V-PLUS WINTER version, which is suitable for applications in winter up to -20°C.

Bossong points out that thanks to the fast curing time of V-PLUS WINTER, even at low temperatures, it has been used for installation of research equipment on Mont Blanc for scientific purposes.

Both V-PLUS and EPOXY 21 anchors have been further tested for underwater fixing, certified by means of extraction tests in situ in Marseille, France. The tests were carried out by INPP (National Institute of Professional Diving) – a specialised team for works in the marine and port environment.

The goal of the underwater test was to verify the performance of Bossong products in an underwater environment. “Thanks to these tests, we were able to draw up a test protocol for the fixing of resins in an underwater environment with pull-out tests that have given outstanding results.”

“We have created an installation procedure, in collaboration with specialised companies, by integrating the needs of the companies with those of ETAG regulations for anchorage in dry, wet and with flooded hole environments.”
