Le premier point pour assurer la stabilit\u00e9 d’une maison pr\u00e9fabriqu\u00e9e est la liaison de sa structure avec le sol. Les fondations doivent \u00eatre con\u00e7ues en tenant compte de la capacit\u00e9 portante du sol et des charges transmises par la structure de la maison. Une \u00e9tude g\u00e9otechnique est recommand\u00e9e afin de conna\u00eetre la composition et les conditions g\u00e9ologiques du site. L’\u00e9valuation du sol permet \u00e9galement d’identifier les \u00e9ventuelles circonstances du sous-sol, comme les racines ou les cours d’eau, par exemple.<\/p>\n
En fonction de la r\u00e9partition des charges le long des \u00e9l\u00e9ments porteurs de la maison pr\u00e9fabriqu\u00e9e (murs, piliers), les syst\u00e8mes de fondations seront g\u00e9n\u00e9ralement peu profonds, comme les fondations sur radier, les semelles en bande lin\u00e9aires ou les semelles sur plots localis\u00e9es. Lorsque la capacit\u00e9 portante du sol n’est pas suffisante, des solutions profondes telles que les micropieux peuvent \u00eatre mises en place afin de transf\u00e9rer les charges vers des couches de sol plus profondes ayant une capacit\u00e9 portante plus \u00e9lev\u00e9e.<\/p>\n
M\u00eame si les fondations peuvent encore \u00eatre construites sur place, elles tendent de plus en plus \u00e0 \u00eatre r\u00e9solues par des \u00e9l\u00e9ments pr\u00e9fabriqu\u00e9s tels que des pieux en bois, en acier ou en b\u00e9ton. <\/p>\n
Bien que la plupart des maisons pr\u00e9fabriqu\u00e9es aient besoin de fondations, certaines, comme les tiny houses, reposent sur une plate-forme sur roues.<\/p>\n","protected":false},"excerpt":{"rendered":"
