For 'Jora Visio BV' a design was made of a sprayed concrete covering. The covering is intended as a decorative finishing layer over a retaining wall and should have the natural appearance of a rock. The planned construction consists of a prefabricated retaining wall of which the elements are not interconnected. Soil is placed against one side of the retaining walls. On the other side of the retaining wall, EPS is applied which is cut into whimsical shapes so that the shape of a sprayed concrete covering achieves a hard finish which further approximates the appearance of a rock. The sprayed concrete covering is connected to the prefab retaining wall by means of steel anchors. These are encased in concrete by mating the EPS. The dimensioning of these anchors is carried out by the engineering firm Emmen. A load of 3 tons on 1 m2 is seen as a situation that can occur regularly and represents an elephant with its front legs supporting or standing against the side of the wall. The sprayed concrete covering must be able to absorb this regular load without cracking. Large loads are seen as a calamity and are only present very occasionally. The finishing layer may crack. The ARMO carbon mesh present serves in the emergency situation to keep any loose debris in place. Repair of this spot will then be necessary.
