It describes the capillary uptake of water when the imbibing surface is fully wetted. In the context of building physics this describes rain on a façade or an imbibition experiment. The suction transport is dominated by the larger capillaries, since their lower capillary tension is more than compensated by their markedly lower flow resistance.’
