Untersuchung des Feuchteeintrags in erdberührtes Ziegelmauerwerk durch die Bewässerung von Kletterpflanzen

Abstract

Investigation of moisture penetration into brick masonry in contact with soil, due to irrigation of climbing plants Based on the results of the project “Moisture ingress into the exterior wall construction of basements due to climbing plants”, the moisture in brick masonry in connection with climbing plants was investigated. Four test stands, which were to simulate a brick basement wall in contact with the ground, were constructed. The moisture content in the soil and the brick masonry was measured. Three of the test stands were each planted with a different climbing plant and the fourth test stand served as reference without planting. The climbing plants basically provided lower moisture in the substrate and brickwork, but no direct correlation could be established. Higher humidity in the substrate does not necessarily mean higher humidity in the masonry. The moisture found in the masonry was then evaluated in accordance with ÖNORM B 3355. In addition, the suction stress curve was determined for the substrate and bricks used, with the aid of pressure pot extractors.
