Geotechnical Support

Due to a water main failure, Holocene Drilling was contracted to drill fourteen soil borings in an upscale urban area along a washed out, subsurface water main alignment. Hole depths ranged from 130 up to 180’ below grade. Grouting volumes ranged from two cubic yards up to 198 cubic yards depending on the void size for a total of nearly 600 cubic yards. Exceptional care was taken working around multi-million-dollar homes and vehicles.
