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.

Individual design possibilities with architectural concrete

Wide-ranging construction methods, such as architectural precast cladding, sandwich facades, steel-reinforced and textile-reinforced concrete, with acidified, blasted, polished, finely washed or smooth surfaces - everything is possible with Hering.

A leader in the development of new concrete technologies

Hering creates numerous special concrete surfaces that go way beyond the conventional. Using its own specially-developed photo concrete technology, it can realize surfaces that include photorealistic images or patterns, as well as lettering and logos in extremely sharp-edged relief concrete. Hering's latest innovation, BlingCrete™ - light-reflecting concrete, allows similarly spectacular effects to be achieved.
