GFRC with Poraver® at the Biennale Weiertal / Winterthur 2019

Sculpture made of glass fibre reinforced lightweight concrete with Poraver® wins audience award


The 6th Sculpture Biennale in Weiertal / Winterthur took place from May 26 to September 8, 2019. It was curated by Christoph Doswald under the motto "Paradise, lost" and delighted its visitors. The sculpture "Sleeping Sculpture" by Swiss artist Christopher T. Hunziker was awarded the prestigious Award of the Audience. The elaborately designed sculpture consists of glass-fibre reinforced lightweight concrete with Poraver® expanded glass (GFRC) from Bürgin Creations.

Dennert Poraver GmbH congratulates Christopher T. Hunziker on this award. Ultimately, we were able to make a small contribution to his success. Only the lightweight concrete used with Poraver® made it possible to transport the sculpture safely to the exhibition site and at the same time guarantee its required strength. Ultimately, the award proves that the material is not only convincing because of its technical properties, but that its surface quality can also easily withstand the aesthetically demanding art world.

The construction of the sculpture took place in a multi-stage structure, in which the rough form was first given to an EPS block. This core was then coated with glass fibre reinforced lightweight concrete with Poraver® (GFRC). This is a high-tech-concrete developed by Bürgin Creations and already successfully used in other projects. At a comparatively low density, it promises excellent strength. GFRC can therefore save up to 50% of the weight of regular concrete. The lightweight concrete enriched with glass fibres is usually sprayed and cures within a very short time so that the material can be further processed. The surface of the sculpture "Sleeping Sculpture", which weighs only 800 kg in total, was smoothed, water-repellent after-treated and prepared for the exhibition. About a quarter of the GFRC concrete's weight consists of Poraver® expanded glass 0.25 - 0.5 mm, which is largely responsible for the weight reduction with similarly high strength values.

The sculpture was seamlessly integrated into the surrounding environment at the exhibition site and also left room for the spetators’ own interpretative approaches. It was therefore not surprising that the colossal figure was chosen by the public as the winner of the Biennale. The transport to the exhibition site in Winterthur had already been spectacularly staged: The "Sleeping Sculpure" was placed on the exhibition grounds with the help of a helicopter.

The process of production


The glass fibre reinforced lightweight concrete (GFRC) with Poraver® is sprayed onto the prefabricated EPS core.

It is a high-tech concrete developed by Bürgin Creations. The lightweight concrete is enriched with the cut glass fibres directly in the spraying device, then sprayed on and cures within a very short time so that the material can be further processed.

The GFRC concrete consists of Poraver® expanded glass 0.25 - 0.5 mm for about a quarter of its weight.
