Present paper describes some aspects of the restoration project recently undertaken in La Zarzuela Racecourse, designed by E. Torroja, Despite the good mechanical work of steel, it has started a deterioration process which has caused the reinforcement corrosion by carbonation. It has been detected corrosion attack in some places due the breaking of the upper waterproofing membrane of the shell and concrete carbonation. For the repair first an assessment of the degree of corrosion was made. The restoration project finally consisted in the injection of all the cracks in order to assure the joint work of the shell and the patching of the deteriorated zones. Profiting these works it was installed a monitoring system of corrosion sensors. We present the results of the application of electrochemical techniques, qualitative and quantitative measures used for assessing the residual service life of concrete structures and monitoring, where real Zarzuela Racecourse
