The article presents hollow foundations that play a multifunctional role: drainage to accelerate the process of consolidation of weak water-saturated cohesive foundation soils, drainage in case of obvious underflooding, anti-barrage in case of latent underflooding, as well as compensating for possible swelling or frost heaving of the clay soils. The adopted design solution makes it possible to transfer the load from the foundation to the soil foundation that includes loose cavity filling material through a more developed support area than a foundation with a flat footing. Unlike the solid foundation, the hollow foundation has a higher bearing capacity by 120 N more, and in the intervals of high loads (> 400 N) the settlement of the hollow foundation develops with an occasional lag from the settlement of the solid foundation. The use of hollow concrete foundations makes it possible to expand the area of application of prefabricated foundations, simplify their manufacture, increase their bearing capacity and ensure their strength and durability, while reducing the material intensity and cost of construction.
