We construct geometric barriers for minimal graphs in Hn xR. We prove the existence and uniqueness of a solution of the vertical minimal equation in the interior of a convex polyhedron in Hn extending continuously to the interior of each face, taking infinite boundary data on one face and zero boundary value data on the other faces. In Hn xR, we solve the Dirichlet problem for the vertical minimal equation in a C0 convex domain taking arbitrarily continuous finite boundary and asymptotic boundary data. We prove the existence of another Scherk type hypersurface, given by the solution of the vertical minimal equation in the interior of certain admissible polyhedron taking alternatively infinite values +∞ and -∞ on adjacent faces of this polyhedron. Those polyhedra may be chosen convex or non convex. We establish analogous results for minimal graphs when the ambient is the Euclidean space R^ n+1.
