Concrete Wall Seismic Retrofit

  • How to Identify if You Have a Concrete Wall Foundation

    If the concrete comes all the way up to the bottom of the floor joists and sits on a sill plate you would have a full height concrete foundation wall.

    The Full Height Concrete Wall Problem

    1. The sill plate and floor joist system is not connected to the foundation.
    2. The connection between the sill plate and the joist system needs to be remedied if your house was built before the invention of plywood.
