River Rock Foundation Repair in Los Angeles

Homes built with river rock foundations are located all through Los Angeles and surrounding cities such as South Pasadena, Pasadena and Altadena. While the curb appeal is very nice there is a danger with these.

First is that the mortar used to hold the river rock together can degrade over time to the point where the rocks will actually fall out or could easily be pulled out. Secondly, because river rock foundations are classified as unreinforced masonry – meaning there is no reinforcing steel (rebar) holding the river rock together, it is not possible to seismically retrofit a this type of foundation.

Alpha Structural has been specializing in river rock foundation repair for over 25 years and will design the optimal solution using a “sister” foundation. This term refers to pouring a new foundation along the inside of the river rock giving the home a foundation while keeping the existing curb appeal.

Depending upon the circumstances, a replacement of some or all of the unreinforced foundation may be necessary, but our preferred solution is most often the installation of a “sister” foundation, which performs extremely well and can be executed for less cost than a replacement.
