Typical foundations for single family homes are constructed as Slab-on-grade or pier and beam.  Since the soils in the Dallas/Fort Worth metroplex are expansive (montmorillonite being the predominant soil), special attention is needed in the design of building foundation. 
     Most slabs-on-grade foundations will move with the soil, they will require "foundation repairs" sooner or later.  This presentation is designed to imform the new home buyer of options which will provide a more stable foundation not subject to the "rock-n-roll" of a slab on grade constructed on expansive soil.
