Bricklayer inspection: I heard if there is any empty drum

  Check the wall tiles, you can gently tap the surface of the tiled surface by hand, and judge whether there is any problem with the empty drum by sound. If it is empty, it must be empty. Either the sand and cement are not proportionately blended with the cement mortar, or the cement mortar is not enough when tiling, which will affect the adhesion of the tile to the wall or the ground. Lao Xu suggested that the installers should check during the tiling process to avoid the problem of rework after all the stickers were posted, but the construction period was delayed.
