Sažetak
Deterioration of telecommunication antenna tower foundations is becoming an issue of criti¬cal importance in the Croatian electronic communications network since little attention has been directed to¬ward the design against failure and premature deterioration of concrete footings and buried tower components in the design period. In this paper, a case study of comprehensive condition assessment and repair works of defective concrete foundations of 3 self-supported antenna towers exposed to extreme environmental loads is presented. In the first step of investigation, visual examination for the preliminary assessment was done, while in the second step, the detailed examination was provided. The mechanical and durability properties were tested in-situ and in laboratory. Factors affecting the durability of tower anchorages and foundations are dis¬cussed together with introduction of repair methods of tower foundations. As presented case studies illus¬trates, concrete deterioration and distress must be carefully monitored and evaluated to determine the appro¬priate repair method
