Construction costs

The use of a prefabricated foundation in prestressed reinforced concrete reduces all the activities inherent in the construction of a foundation with a traditional system in place until they are eliminated.
The positioning of the prefabricated plinth requires less excavation and therefore less subsequent filling, just as the absence of a containment structure avoids the need for specialized labor (carpenters, blacksmiths) and reduces the use of related products (boards, nails, iron, shaping machines, miter saws, electricity, etc.).

A foundation with guaranteed costs

The elements of the prefabricated Foundation “Themelio” are produced entirely in our factory with a standardized industrial process that allows us to provide precise and definitive costs, already in the design phase.
The use of a prefabricated foundation in prestressed reinforced concrete reduces construction site costs by up to 90%, as it requires less excavation and subsequent filling, thus avoiding the need for specialized labor with a consequent reduction in safety costs.
