We therefore provide project-specific advice, i.e. referring to the respective individual case.If necessary, please contact our interlocutors in the marketingdepartment or our department for application technique. a)Foundation d)Vibratory compaction Sketch of principlescreed mixture or with flexible thin-building bed mortar is of coursealso possible. For this, surface vibrators with rubber apron and a com-paction capacity of approx. 16 to 20 kN must be used on a dry surface. After the vibratory compaction, subsequent sanding is required. e)Processing c)Pointing Exact cutting to size is achieved best by means of wet cutters equipped with diamond disks. In the case of unbound laying, dry silica sand, gravel sand or crushed stone fines of the granulation 0/2 are used: before the vibratory compaction, introduce the material in sections and then sand the surface. If necessary, a bound pointing is also possible, e.g. by means of commercially available point- ing mortars for pavings. The instructions of the respective manufacturer must be observed. f)Cleaning Buchtal Piazza requires no impregnation, sealing or any oth-er surface treatments. Rain, sun, snow etc. and the regular use effect a sort of natural maintenance and patina. For the basic cleaning in the case of heavy soiling, high-pressure cleaning apparatus or road-sweepers can be used. In the case that pointing material is mechanically removed, subse- quent sanding is required.

Application

Buchtal PiazzaStone chips bed 3-5 cmAntifreezing and base layerPlane The details especially with regard to the base layer are stipulated by the DIN 18318. For example, a slope of at least 2 to 2.5 %must be provided for the drainage of the paved surface.As bedding material, a mixture of crushed stone fines/stonechips of the granulation 0/5 must be used. The compacted bed- ding must have a thickness of 3 to 5 cm. b)Laying The laying is carried out on the evened bedding in conformity with the height, the angle and the alignment. The DIN 18318 specifies a joint width of 3 to 5 mm, because otherwise the com-pensation of inevitable manufacturing tolerances would beimpossible. Spacers have not been used. They do not serve for ensuring a uniform joint pattern, but for preventing chipping. In the case of Buchtal Piazza, this is achieved by the slightly conic shape of all the four sides. Besides the frequently used unbound laying on stone chips bed, a bound laying in a slightly moist 14 14
