Abstract

The present invention relates to a process for surface treatment of elements comprising a hydraulic binder where the process comprises the following steps: Placing the elements under a pressure lower than the ambient air pressure for a certain period of time; arranging a mist of an impregnating agent immediately around at least part of the element, where the molecular size of the impregnating agent is less than or equal to 0.2µm. Furthermore, the invention also relates to apparatuses for carrying out the process.
