Seismic / Landslide Hazards and Construction Defects Analysis, Foundation Failure Analysis, and

Structural Integrity Analysis, plus Inspection, Reinforcement, Restoration, Reconstruction, and Replacement; as well as Design and Construction of New Dams, Levees, and Other Structures

There is a Major Need for Structural Inspections and Repair of our Dams & Levees:

A television series on the History Channel, entitled Inspector America, with inspection expert Timothy Galarnyk, examined the dangers of corroding infrastructure around the United States.

Also, on the History Channel, a 2-hour program, entitled The Crumbling of America, addressed the many threats that our deteriorating bridges, highways, dams, levees, water delivery systems, sewage systems, and power grids pose to our lives and our way of life in our nation. Much of this infrastructure needs to be rebuilt.

And . . . the levee breaks of the spring of 2011 in Missouri, Arkansas, and elsewhere have exposed the great needs for the repair and rebuilding of much of our levee system in the U.S.

What Structural Integrity Solutions Can Do:
