There are various reasons for the formation of cracks on the facade. Cracks can be divided into shrinking and structural cracks. In the case of the first group, i.e. shrinking cracks are caused by material defects or improper material application.
They have especially negative impact on render layer, because of water penetration through the tiny cracks, which has a damaging effect on the facade condition. Integrating and smoothing shrinking cracks has an important impact on facade condition and appearance.
Another group of flaws are structural cracks. Here, an effective repair of the wall requires consulting its designer. To repair any structural crack in a responsible manner it is necessary to examine the reason behind it and specify an optimum repair and a damage stabilization method.
