Engineering & Building Construction Contractors: Specializing in  Technically Challenging Construction Projects in the Bay Area.

We are a family owned and operated specialty engineering and construction contractors company operating in California since 1978 encompassing two generations. We are among the first construction contractor firms to install Helical Piers Anchor Products for residential foundation underpinning in the U.S. beginning in the 1980’s as an original A.B. Chance certified installer. We continue to conduct construction contractor business throughout the San Francisco Bay Area and beyond, blending innovation and creativity to execute our work on new and existing structures. Much of our work involves technically challenging construction in very difficult and sensitive environments such as for seawall construction and repair. We specialize in Helical Pier Installation, New Foundations and Foundation Repairs, and Retaining Walls for commercial and residential applications.

Sunstone corrects, protects, saves and creates space.

Helical Piers Installation for Foundations and Foundation Repairs

Helical Piers or anchors are deep foundation solutions used to secure new foundations, or repair existing foundations. Because of their design, helical piers offer an easy to install solution in buildings or environments where soil conditions and other factors don't lend themselves to shallow foundations.
