Slope stabilization design is core area of Cefali & Associates. We have designed and overseen the construction of over 75 slope/hillside stabilization projects in the western states. These run the gamut from large landslides effecting dozens of homes and buildings to smaller slides on a single family residence sites.
Remediation of these generally include a combination of mechanical stabilization as well as permanent dewatering and geometry modification. Mechanical stabilization may use permanent tiebacks and soldier piles or perhaps shear pins. The slope itself is generally re-graded to improve its stability. This may involve laying it back at a flatter slope and increasing the mass of the toe.
