One of the creatures that exist in this world co-exist with humans is stone, the stone is various kinds from small to large. Geologically, rocks are solid objects that are naturally derived from minerals and / or mineraloids. The Earth's dense outer layer, the lithosphere, is made of rock. In rocks are generally three types, namely igneous rocks, sediments, and metamorphs. Stone can serve as a raw material for building something. In rock buildings are usually used on the foundation of buildings for buildings with a height of less than 10 meters. The ability of batukali that can withstand heavy loads is of course highly favored until this era, where the installation of the foundation is combined with the technique of mounting strauss pile / drill pile, chicken claw concrete, etc. to withstand shocks when there is vibration from the ground or vibration produced by the surrounding environment for securing the robustness of the founding of a solid building.
