A triangulation of a hyperbolic 3-manifold is $L$ -thick if each tetrahedron having all vertices in the thick part of $M$ is $L$ -bilipschitz diffeomorphic to the standard Euclidean tetrahedron. We show that there exists a fixed constant $L$ such that every complete hyperbolic 3-manifold has an $L$ -thick geodesic triangulation. We use this to prove the existence of universal bounds on the principal curvatures of ${{\pi }_{1}}$ -injective surfaces and strongly irreducible Heegaard surfaces in hyperbolic 3-manifolds.
