Process, in particular for introducing dampproof courses into building walls

摘要

In a process for sealing and/or introducing dampproof courses into building walls, in which the wall is provided with bore holes at intervals in the region to be treated and said bore holes are subjected to a two-component polyurethane resin under pressure, the aim is to provide a solution which avoids unnecessarily high amounts of the sealing resin being injected into the hollow cavities of such bricks or structures and the thermal insulation behaviour is immediately improved. This is achieved in that, if hollow cavity bricks are present, the hollow cavities are first filled by foaming with a polyurethane foam and subsequently the two-component polyurethane resin is introduced.
