Moisture transport processes have often been the subject of research in the past and have been sufficiently analysed. Many of the water transport mechanisms described in literature require a wettable pore wall for water transport. This is not applicable to hydrophobised building materials.

The aim of the research is to investigate the water transport through hydrophobised areas of mineral building materials and the qualitative and quantitative description of the transport mechanisms in constrast to conventional mechanisms with wettable pore walls. In doing so, it is necessary to find model approaches and compare them to experimental data. In some places, measurement methods have to be modified in order to obtain valid results.

Industrial floors

Industrial floors are coated with sometimes very complex, multi-layered systems that require precise planning and processing. To ensure this, adjustments to materials are always necessary. In addition to the coating materials and substrates used, the evaluation of the requirements of specific industrial sectors and the measurement of both the actual loads and the concrete application conditions are topics that constantly require new perspectives. Last but not least, the analysis of damage to industrial floor coatings serves to uncover weakpoints and to initiate innovation.
