There are many different types of architectural concrete:
Smooth architectural concrete: This architectural concrete is not processed, but remains smooth as formwork.
Essential features of the exposed concrete surfaces are, on the one hand, the uniformly closed appearance and, on the other hand, the knowingly permitted naturalness and liveliness of concrete as a building material.
Smooth surfaces present concrete as a building material particularly elegantly and have the great advantage of not being subject to architectural fashions and thus being timeless.
Washed architectural concrete: During washing, the upper layer of fine mortar is removed by means of water jets and the grain size is completely exposed. This is made possible by the use of a paste-like contact retarder, which is applied to the formwork before concreting.
As a result, depending on the depth of washout and the grain used, the result is a more or less strong structure and liveliness of the surface, in which the grain dominates the appearance.
Acidified architectural concrete: An acid is used to remove the top layer of fine mortar, which is initially smooth as formwork, and roughen the cement skin.
The use of water allows the complete neutralization of the acid.
The result is a velvety, harmonious surface, in which the fines of the concrete in particular characterise the look.
Sandblasted architectural concrete: In sandblasting, the top layer of fine mortar is mechanically removed by means of blasting material and the grain is broken.
In order to obtain a uniform surface appearance with this processing method, we only use employees who have been trained for many years with particularly extensive experience, a good feeling and a good eye.
The result is a matt surface with a strong character, in which both the interaction between the grain size used and the concrete matrix (fines) and the processing depth of the visible surface provide the decisive touch.
Honed architectural concrete: During grinding, approx. 3 to 6 millimetres of material from the concrete surface is removed by means of diamond grinding heads and the grain size is completely visible.
This machining method is done by multi-stage milling and polishing on our CNC-controlled bridge grinding machine.
The water required for this process is purified and returned in the company's own reprocessing plant. This is how we manufacture in a particularly resource-saving way.
The result is a smooth, glossy and extremely representative surface, in which the interplay between the grain size used and the concrete matrix (fines) gives the visible surfaces a particularly lively expression.
Brushed architectural concrete: Brushed surfaces will surprise you with their particularly smooth yet lively surface appearance. They are a special eye-catcher for any façade and give buildings a truly unique look.
Technical Information
Surface protection
Architectural concrete should not lose its exclusive design over time. Therefore, sensible surface finishes are becoming more and more important as a protective layer.
Whether moisture-repellent and/or dirt-repellent or complete impregnation systems with integrated graffiti protection: they protect your investment sustainably and permanently against corrosion and façade contamination.
Surface-protecting impregnates are applied at the factory after surface treatment and, if desired, completed after assembly on the construction site to form a complete protection system.
