The description concerns a working method and system (200) for inspecting the liquid tightness of a floor (20) by increasing the pressure on the underside of the floor (20). To this end, according to the invention air is pumped directly under the floor and into the possible joints (22) so that no pressure loss takes place as a consequence of the ground (10) on which the floor (20) rests. A system for the execution of this working method can therefore have a simplified construction, and the installation of the system can be done in a simpler and faster manner. In a special variant embodiment the present invention even provides a fully mobile system (200) in which, apart from a possible cover plate (24), no parts remain behind at the measurement location, so that the system can be used at several locations and is therefore more profitable. <IMAGE> |
