HSI Engineering, Inc. is a geotechnical engineering firm focused on finding engineering and constructability solutions that address today's economic, environmental and engineering challenges.   

We are the leader in the design and execution of chemically stabilized structural sections. What is Chemical Soil Stabilization? In a nutshell, it's the process of mixing soil and/or aggregate with a cementitious binder, such as Portland cement, quicklime, or Fly Ash, and a sufficient amount of water. When compacted, this mixture results in a highly dense, strong, stable and impermeable section, ideal for a variety of structural applications. 

HSI provides a number of services related to geotechnical  engineering, chemical soil stabilization and materials testing. Our clients include public agencies, engineering firms, contractors and property owners. We’ve worked on a variety of different projects from new roadways, to pavement rehabilitation, to water resource projects to geotechnical investigations for new home buyers.
