Hyperbolic Paraboloid Slab Foundation

Abstract

Traditionally, slab foundation is made up of reinforced flat plates. Replacing these plates by others with a hyperbolic paraboloid geometry can be considered an alternative for structural foundations of residential, commercial, or industrial buildings, especially in soils with low bearing capacity. When compared to traditional slab foundations, the hyperbolic paraboloid foundation reduces the consumption of materials (steel, wood, and concrete), which helps to reduce the environmental impact caused by the extraction of raw materials. Although this type of foundation is easy to build, certain precautions must be taken into account during construction. Therefore, this article describes the practical characteristics related with each construction stage of the foundation, namely the precautions to be taken with the location, excavation, execution of the forms and waterproofing of the foundation modules
