Range of application This Appendix to the Product Manual should give a short overview of the installation steps for the TECCO® slope stabilization system. This appendix is only valid in combination with the most recent edition of the Tecco® “Slope Stabilization System Product Manual”. In the Product Manual, the entire process of installation, with every possible detail needed, is described. The TECCO® slope stabilization system consists of mutually adapted coordinated acting system components. The TECCO ® system is a designed system. Product Liability Clause Rockfall, landslides, debris flows or avalanches are sporadic and unpredictable. Causes can be e.g. human (construction, etc.) or environmental (weather, earthquakes, etc.). Due to the multiplicity of factors affecting such events it is not and cannot be an exact science that guarantees the safety of individuals and property. However, by the application of sound engineering principles to a predictable range of parameters and by the implementation of correctly designed protection measures in identified risk areas the risks of injury and loss of property can be reduced substantially. Inspection and maintenance of such systems are an absolute requirement to ensure the desired protection level. The system safety can also be impaired by events such as natural disasters, inadequate dimensioning parameters or failure to use the prescribed standard components, systems and original parts; and/or corrosion (caused by pollution of the environment or other man-made factors as well as other external influences).
