SLIDE CORRECTIONS USING DEEP INTERCEPTOR TRENCHES

The California Department of Transportation's (Caltrans) methods for dewatering large soil masses to reduce or eliminate hydrostatic pressure have included installing horizontal drains, vertical wells, or constructing stabilization trenches. Caltrans' experience indicates that the use of backhoes capable of excavating to 40 ft (12.2 m) presents an innovative, safe, and cost-effective method to construct deep interceptor trenches to control ground water seepage.
