Unreinforced Masonry Seismic Retrofit

  • How to Identify Unreinforced Masonry Seismic Retrofit

    If the foundation of your home is visibly brick, old clay block, or unreinforced concrete block this would be considered an unreinforced masonry foundation.

    The  Unreinforced Masonry Seismic Retrofit Problem

    Brick and unreinforced masonry does not have lateral strength because there is nothing connecting the wall together (ie. there is no rebar). At Earthquake Tech, we say Every Brick Is An Island. Hence, during an earthquake the foundation will collapse. It is more than likely that your 100 year old foundation is not going to withstand an earthquake, emergency professionals call these types of homes “standing rubble”.
