Basis is used in a nonphysical sense: "Healthy scepticism is the basis of all accurate observation" (Arthur Conan Doyle).
Foundation often stresses firmness of support for something of relative magnitude: "Our flagrant disregard for the law attacks the foundation of this society" (Peter D. Relic).
Ground is used figuratively, especially in the plural, to mean a justifiable reason: grounds for divorce.
Groundwork usually has the sense of a necessary preliminary: "It [the Universal Declaration of Human Rights] has laid the groundwork for the world's war crimes tribunals" (Hillary Rodham Clinton).
