Example embodiments generally relate to the field of mesh installation on a rock surface (140). An apparatus (100) may obtain scanning data of a rock surface to detect at least one first mesh installed on the rock surface; determine, based on the scanning data, a first position of the at least one first mesh (404); determine, a second position for installing a second mesh (401, 402) on the rock surface, wherein the at least one first mesh and the second mesh are configured to overlap at an edge of the at least one first mesh, when the second mesh has been installed on the rock surface at the second position; and control installation of the second mesh on the rock surface at the second position.
