Sankey Diversion

The Sankey Diversion project was part of the Natomas Mutual Water Company’s larger American Basin Fish and Screen Habitat Improvement project. Throughout the multiple year project duration, Blackburn Consulting provided field and laboratory soils testing and analysis. This included compaction/density testing for new levees, new structure foundations, roadway subgrade, and trench backfill. Blackburn performed quality assurance materials testing to verify contractor’s compliance with the project specifications. We also provided sampling and analysis for cementitious products including structural concrete, shotcrete, high strength grout, and Controlled Low Strength Material (CLSM).
