| Zusammenfassung: | A spandrel supporting an upper story upon a lower story of a construction having exterior and interior walls bounding a site for collecting water seepage through the porosity of the brick construction material of the exterior wall, on which spandrel there is a waterproofing membrane to confine the water seepage to the space between the walls and a porous drainage fabric to drain excessive water to the exterior and as to nominal seepage to allow air flow through the drainage fabric to cause its evaporation. |
