Binalar, k\u00f6pr\u00fcler, katl\u0131 otoparklar ve benzeri yap\u0131lar en \u00f6nemli \u00f6zel ve kamusal yat\u0131r\u0131mlar aras\u0131nda g\u00f6sterilebilir. Yine de, zamanla, bu yap\u0131lardaki betonarme \u00e7elikleri eskir ve paslan\u0131r. Bu durum da yap\u0131da g\u00fc\u00e7 kayb\u0131na sebep olur. E\u011fer onar\u0131m masraflar\u0131 da y\u00fcksekse, bu durumun alt\u0131ndan kalkmak olduk\u00e7a zor bir hal al\u0131r.

Yap\u0131da zaten bozulmalar ve \u00e7\u00fcr\u00fcmeler ba\u015flad\u0131ysa, yine de tasarruflu ve uygulanabilir \u00e7\u00f6z\u00fcmler bulmak m\u00fcmk\u00fcnd\u00fcr.
\nProtectosil\u00ae CIT \u00fcr\u00fcn\u00fc bu ama\u00e7la geli\u015ftirilmi\u015f silan bazl\u0131 korozyon \u00f6nleme sistemidir ve Evonik\u2019in en \u00fcst\u00fcn \u00f6zellikli \u00fcr\u00fcnlerinden birisidir.

Protectosil\u00ae CIT \u00fcr\u00fcn\u00fc hem suyun ba\u011flanmas\u0131na hem de klor\u00fcre maruz kal\u0131nmas\u0131na kar\u015f\u0131 etki g\u00f6sterir. \u0130lk olarak, Protectosil\u00ae CIT \u00fcr\u00fcn\u00fc suyu bloklamak i\u00e7in derin bir bariyer olu\u015fturur ve bu durum klor\u00fcr iyonlar\u0131n\u0131n donat\u0131ya ula\u015fmas\u0131n\u0131 engeller.
