Based on current European standards such as EC1, EC2 and EC7 as well as application standards for anchors, piles, nails and bolts, new corrosion protection systems for geotechnical stabilisation systems in concrete reinforcement steel quality, e.g. SAS 670/800 threadbars, will be discussed. Grout cover, permissible crack widths, zinc and corrosion rates will be defined and lifetimes of up to 120 years for different soil aggressivities specified. The data for integrated systems have already been included in various approvals and approval drafts. Integrated systems mean that consistent durability for pre-stressed permanent anchors up to robust reinforcement steel, e.g. rock bolts, for different aggressive soils under tensile load as well as compression load can be covered. Main criterion gives EN 1537, e.g. chapter 6.9.
