Düsseldorf (D), Kö-Bogen, Conceo Light Granite blasted

Conceo defines surface in a new dimension. With sizes up to 150 x 150 cm, this high-performance concrete slab enables completely new design possibilities for squares, terraces, stairs and paths. Surfaces appear more spacious generous; the proportion of joints is significantly reduced. One single size allows designing paths of a piece. Conceo elements set at different levels add up to stairs that seem to float. The slip-resistant large-sized slabs are available in two different surface qualities, each in two shades: With a puristic, elegant, smooth surface in the colours Alpine White or Meteorite Anthracite and alternatively with a finely blasted surface with natural stone chippings in Granite light or Anthracite. Conceo slabs are available in three sizes:150 x 150 cm, 150 x 75 cm and 75 x 75 cm; for planners and architects, any customized size is available on request.

According to the special characteristics of the heavy-duty concrete surface the thickness of the stone is reduced up to 5 cm. (not available as step slab).
The dimensions are: 150 x 150 x 5, 150 x 75 x 5 und 75 x 75 x 5 cm.

Properties

  • Large-sized slab system with high-quality visible surfaces due to the use of natural stone chippings in combination with a specially developed blasting process in a wide range of colours (blasted and velvety).
  • With a very fine and dense high performance concrete surface, velvety® or acidified. The special surface treatment creates velvety and elegant concrete surfaces.
  • The large-sized Conceo slabs in 8 cm thickness are also available as self-supporting step slab with machined visible edges. Ideal solution for designing innovative stair solutions.
  • Reduced number of joints in the surface due to the large sizes.
  • Blasted, acidified and velvety surfaces are slip-resistant.

Building instructions for a self-supporting step system

Building instructions for a self-supporting step system with Conceo steps

The Conceo step slab for self-supporting  are available in the standard dimensions 75 x 75 x 8 , 150 x 75 x 8 en 150 x 150 x 8 cm and in other special dimensions on request.

The Conceo step slabs are suitable for completely covering in a mortar bed. The steps may have an overhang of maximum 30 % of their length resp. width on one or two sides of the foundation. The standard slabs are not suitable for a self-supporting installation on laterally stair strings. The adjuster of the Conceo step slab are machined all-over. Because of aesthetic reasons, the controller of the foundation should be painted dark. Resulting to the shadow effect, they are no longer noticeable.
 
The foundation of the Conceo step slab is carried out in a similar manner as a standard step slab.  But the covering of the step slab may occur to a completely mortaring. To avoid tensions as a result of different shrinking of foundation and step slab, the substructure should be dried as possible.

For glueing the surface of the foundation and the bottom of the Conceo step a "primer" is needed. We recommend a frost-resistant flexible mortar. For a better adhension the backsides of the step slabs are roughened. The layering on footfall sound isolation or other films is not allowed.

For a quicker drainage of the surface, a down grade of 1 % is to be provided.

For laying of the Conceo step slabs we recommend the use of vacuum laying equipment. The weight of the slabs is addicted to the size, it is from 281 kg up to 551 kg (180 kg / m²) per item. The stairway can be walked-on after curing of the mortar.

Please ask for special solutions, for example slabs with notches, slabs in special dimensions, step systems with large overhangs, slabs with components for an electrical system or slabs with floorboards.
