Unsaturated Soil Technology is a company dedicated to bringing unsaturated soil mechanics into routine engineering practice. Soil mechanics has been slow to emerge / become implemented for unsaturated soils. Several aspects of classical soil mechanics needed to be re-addressed and extended to accommodate unsaturated soil behavior. For example:

• Theories needed to be developed and formulations extended to accommodate the behavior of unsaturated soils.
  
  
• Unsaturated soil mechanics needed to be taught to university students and practicing geotechnical engineers as part of the soil mechanics curricula.
  
  
• The practice of unsaturated soil mechanics problems generally involves the solution of highly nonlinear partial differential equations because of the constitutive non-linearity associated with desaturation of a soil.
  
  
• Laboratory soil testing apparatuses needed to be developed and made available for testing unsaturated soils. The primary equipment required is an apparatus to measure the soil-water characteristic curve (SWCC) for soils.
  
  
• Devices for the measurement and monitoring of soil suction are necessary to ensure the accuracy and reliability of unsaturated soil theories.
  
  
• Research was necessary to establish appropriate protocol procedures for the implementation of unsaturated soil mechanics.

Unsaturated Soil Technology is striving to meet all the needs associated with the furtherance and implementation of unsaturated soil mechanics into geotechnical engineering practice.
