The rehabilitation of reinforced structures is during last 10 years an up-to-date, dynamically developing trend in building industry. The subject-leaver obtains actual information about the whole rehabilitation process i.e. about diagnostics performance of degraded structure (method, tests, evaluation) design of rehabilitation and its execution (technology, materials etc.). A component of execution is also the description of methods and frequency of checking tests during the rehabilitation process and after its end.
The next component of the subject is knowledge concerning rehabilitation of brickwork structures. The student obtains here information about reasons of failures and the possibilities of their rehabilitation. The last component of the subject is the rehabilitation of wood.

Extent and forms are specified by guarantor’s regulation updated for every academic year.
