General engineering contractor Bert W Salas Inc in Lakeside operates from the Hwy 67 corridor under CSLB Licenses #275199, #365539, and #228645, with California DIR Registration #1000004246. Founded in 1999, the firm excavates and installs underground utilities for residential and public-works sites—the subsurface infrastructure that precedes septic and sewer construction managed by Anytime Septic Service on Gardena Road. Project history spans San Diego County, including hauling Class 2 bedding rock for campground utility trenching at coastal state beach facilities. Earthwork capabilities extend to rough grading, trenching, and compaction for residential pads in the hillside terrain east of Lake Jennings, terrain that later requires finish grading and erosion-control materials available through Alpine Landscape Materials on Tavern Road. The fleet handles cut-and-fill operations exceeding 5,000 cubic yards per site, with vibratory roller compaction to 95-percent relative density per ASTM D1557 Modified Proctor standards.
