During construction of buildings in urban areas, sometimes there is a need to blast solid rock mass in the immediate vicinity of the surrounding buildings. In that case, the aim is not only to increase the efficiency of blasting, but also to reduce harmful effects of ground vibration induced by blasting. At the same time, it is very important to protect the buildings located in the safe zone from the blast site as well as remaining rock mass around the blast site. This can be achieved by the formation of artificial screens. Artificial screens represent discontinuities in the rock mass placed between the blasting site (source of seismic waves) and building to be protected. The formation of artificial screens using expansive mortars is presented in the paper. Expansive mortars are environmentally friendly products. They do not cause shock waves, ground vibrations, air blast, flyrock and do not release toxic fumes as side effects of blasting process which may occur. They do not cause excessive breakage to the surrounding rock mass.
