PURPOSE:To obtain a foundation protected from slide movement by a method in which cobble stones with acute tips are projectingly laid over a slab to form concrete cobble stones in such a way that the cobble stones are directly laid on the ground. CONSTITUTION:Cobble stones 3 with acute tips are projectingly laid over a slab 2 to form concrete cobble stones 1. In a foundation work for a building, cobbles stones 1 are laid by positioning the cobble stones 3 downwards on the ground excavated and struck by a rammer, etc., to cause the cobble stones 3 to penetrate into the ground. The settlement and slide movement of the foundation so constructed can be prevented completely.
