Shotcrete Construction Company

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.

All our field employees are unionized. We hire specialized personnel to ensure highest quality materials and products for all jobs.
