Planners must plan according to “state-of-the-art” standards and companies must execute their work according to “state-of-the-art” standards.

In the regulations of the research company for road and traffic the importance of the prevention of displacements and rotations was indicated in the data sheet MFG / R2 (January 2014) “state-of-the-art”.



According to the paving brochure 2014 of the SLG (Association for Road, Landscape and Horticulture) displacements shall be interpreted as an optical defect, if the central axis of a joint is offset by > 5 mm. This situation often occurs in the first months after operational release (warranty period)!
The construction company must record the displaced areas of the area as they change, and reposition them again. The problem with the situation will probably reoccur after a relatively short period of time, if this is not the case with a shifting prevention device – a permanent application! These processes demand time and money and create hassle, and also result in a damaged reputation on behalf of the company executing the work. If unintentional shifting prevention devices for hazardous areas were not taken into consideration in the planning phase, it is imperative that a concern should be reported and registered. You can find them in the section: Downloads. In the event of using shifting prevention devices, areas are protected against potential problematic displacements in a reliable manner. Displacements, rotations or the pressing and widening of the formation can therefore be prevented.
Critical and hazardous areas are, according to the RStO [German standardisation directives of circulation area superstructure areas], 12 curves, sections that are > 5% downhill, stop areas, turning points or tracking areas. The use of shifting prevention devices is essential in these areas. Only these areas are protected.

Cross-joint formations are particularly vulnerable in traffic. According to DIN 18318, these formations should be done without. However, if these formations are executed for various reasons, shifting prevention devices should be used according to the data sheet of the research company for road and traffic (FGSV).

We offer you support in the planning and execution of projects with natural stone and concrete in large formats taking into consideration the axle loads and the expected axle transitions (minimum thickness calculation).

With the execution planning available, we will share our experience in anchor positioning with you. In the past 10 years about 500 objects have been protected by us with the use of shifting prevention devices.

The newly developed Verschi vario + has a universal protective effect due to its numerous applications. Depending on the protective effect, this displacement protection anchor conserves numerous supplementary modules: e.g. possible movement profiles.

We are happy to provide you with further documentation on the following aspects:
– Thickness calculation
– Current regulations
– Tender specification texts, installation videos
– Technical drawings/installation
– Notes: Superstructure (VB) installation examples with „Verschis“

Using our „Verschi vario +“ and „Verschi 485“ will prevent the following damage cases.
