Tella Firma Foundations use a proven, patented process of elevating a slab-on-grade foundation above the ground to create a protective void. This innovation isolates the slab, helping protect it from damaging soil swells, contractions, and movement caused by light earthquakes.


Use Tella Firma Foundations for your next home, multi-family, or commercial project.
