The structure and all its elements must be load-bearing, safe and serviceable. Due to time and external factors such as wind, thawing and freezing cycles, seismic activity, the structure of the concrete is disturbed and this leads to a reduction in the load-bearing capacity of the element. For vertical elements (columns), this usually means that the member´ strengthening must be used. The most common way of strengthening a concrete column is to use a new reinforced layer of concrete. In this case, great emphasis is placed on the contact between the original and the new layer of concrete. This article deals with two ways of surface treatment, such as notches and indents using different types of strengthening.
