Schnabel believes that the competitive advantage that we offer our customers is a result of our commitment to continued incremental innovation in the products and services we provide.  Because of the inherent risk involved in building underground, building something that we cannot see, we believe the process should be incremental with new techniques evolving from those that we have tried, tested, and proven to work.  With these incremental improvements our productivity increases, and our customers get the benefit of safe, reliable, and cost effective solutions for their earth retention and deep foundation projects.
