    Earthquake retrofitting also takes a very close look at cripple walls. These walls are structures that connect the foundation to the floor base.

    Commonly seen in crawlspaces, cripple walls are one of the greatest liabilities when an earthquake strikes.

    Without proper reinforcement through a seismic retrofit, the cripple walls are particularly susceptible to the sideways movement that a home experiences in an earthquake.

    The movement can cause one or more of the cripple walls to collapse, which causes the entire house to shift and fall.

    The Uniform Code of Building Conservation and the Los Angeles Building Code, specify the type of plywood to be used in building shear walls (5 Ply plywood), the types of nails to be used and spacing of the nails, methods of attaching shear panels to the mudsill, and methods of attaching them to the floor of the house (8d common Nails).

    Maintain and Replace

    Earthquake Retrofitting

    An important part of earthquake retrofitting is dealing with a structure’s old construction that may be worn out and rusted.

    Over time, moisture becomes trapped between the mudsill and foundation. The rust degrades the metal, which causes it to move and not stay in place when the earth starts to move.

    This gives unwanted water an entrance into the structure, which can causes a whole set of additional problems. In addition to having bolts installed, other various aspects of the structure should also be inspected occasionally and replaced when necessary.

    Frequently Asked Questions

    Is it expensive to have my home earthquake retrofitted?
    Do you drive your car without insurance?  If not, why would you live in a home that hasn’t been earthquake retrofitted?   We can say with certainty that it is much more affordable to retrofit your home against earthquakes, than it is to repair your home after it is damaged in an earthquake! The standard earthquake retrofitting job may cost a few thousand dollars, but the damage from a single earthquake can easily cost more than 10 times that amount.  Moreover, in some circumstances, the extent of earthquake damage may be so severe and extensive that the property is not repairable, forcing the home owner to either rebuild the home from scratch or purchase and move into a new home.  And so the question is, how can you put a cost on sleeping better at night, knowing that you and your family are safe? Of course such peace of mind is priceless! And don’t forget that you might even receive a discount on your homeowner’s insurance premiums!
