Acidified surfaces

An acidified surface is achieved if the top layer of fine mortar of the concrete surface is removed by means of an acid. Only the cement skin is removed, the abrasion giving the surface its artificial appearance.

The concrete determines the colour

It is possible to obtain different “acidification depths”. The colour of the surface is mainly determined by the finest aggregates in the concrete since the coarser aggregates are only exposed to a very limited extent.

Precast concrete cladding panels from Hering

Architectural concrete supplied by Hering stands for quality

Concrete has become an integral part as construction material for buildings, both for façade design and for structural prefabricated reinforced concrete components. Individually designed buildings with imposing façades are a standard feature of architecture. Whether curtain façades or sandwich façades, acidified, sand-blasted, polished, washed, smooth-shuttered or concrete rainscreen surfaces, Hering makes it possible. An image in photo concrete or a logo in relief concrete? No problem – Hering can do it.

Hering - a leader in developing new concrete technologies

With its thin walled betoShell® GFRC façade panel, Hering has succeeded in taking a big step forward in the development of façade technology. Being only 20 mm, it is perfect for remedial work on façades while being equivalent to conventional concrete façade elements in terms of its properties.

Our products for the architectural concrete sector are not yet available in the USA.
