For the formation of a foundation for masts, posts, pillars, etc.,wherein the foundation comprises a foundation tube (3) which is lowered into a pre-drilled hole (2) in the ground (1), where the pre-drilled hole has a diameter larger than the diameter of the tube (3) and where at least the space between tube (3) and ground (1) is filled with a casting mixture (8), e.g. concrete, a tube (3) is used which is designed with perforations (4) in its lower area. The foundation tube (3) is equipped with a coating which gives the tube protection against corrosion, and possibly also an electrical insulation. The coatings can have a rough surface in order to crate the best possible adhesion to the castrng mixture. In order to ensure that the coated foundation tube (3) is safely lowered into the hole, it is first lined with a casting (13), which is removed during or immediately after the casting.
Tube (3) muni de perforations (4) dans sa partie inférieure et utilisé dans la formation d'une fondation pour des mâts, des poteaux, des colonnes ou analogue, où la fondation comporte un tube de fondation (3) que l'on introduit dans un trou (2) foré à l'avance dans le sol (1), le diamètre du trou étant supérieur à celui du tube (3), et au moins l'espace compris entre le tube (3) et le sol (1) étant rempli d'un mélange coulé (8), par exemple du béton. Le tube de fondation (3) est pourvu d'un revêtement de protection du tube contre la corrosion, et éventuellement d'un revêtement d'isolation électrique. Les revêtements peuvent avoir une surface rugueuse afin d'optimiser l'adhésion au mélange coulé. Afin d'assurer l'introduction en toute sécurité dans le trou du tube de fondation (3) revêtu, ce tube est d'abord muni d'une enveloppe (13) que l'on retire pendant la coulée ou tout de suite après.
