Aus Sand erbaut – Saugspannungen infolge Teil sättigung ermöglichen scheinbar Unmögliches

Built of sand – tension from unsaturation enable unimaginable sculptures. Partly saturated sand enables to form astonishing figures and sculptures of sand. Curvers are forming sculptures, which are presented in open air exhibitions. It can be shown, that suction caused by waterfilms in the pores of the soil is the physical reason for the tension stress of unsaturated soils.
