Dees-Hennessey Inc. maintains high safety standards. We maintain a high track record of innovation and for completing projects on time and on budget. 

Dees-Hennessey Inc. has served Northern California since 1985 and is locally owned and operated. It was begun in 1985 when Delbert Dees, an expert in shoring, and Pete Hennessey, an expert in excavation, branched out and started a company together. 

Dan Evans, a shotcrete expert, joined the company in 1986. Together, our staff of engineers has more than 100 years of combined experience. Soon after starting in shoring they developed a structural shotcrete division and soon became one of the leaders on the west coast in shotcrete. Today, with the expertise and knowledge of the current partners Dan Evans &  Jason Myers, Dees Hennessey is one of the leaders in the shotcrete industry and is continuing the innovation of shotcrete mixes to allow for higher strengths in the shotcrete and aiding in more complex shotcrete reinforcement.

We hire specialized personnel to ensure highest quality materials and products for all jobs.
