Quake Tip of the Week

I’m Bolted, I’m Ok? 

I’m hearing from way too many folks who have taken a peek in their crawl space, seen some bolts connecting their “mudsill” to their foundation, and are thinking “Oh, good, my foundation is bolted, I’ve got a retrofit.” 

A “bolted foundation” is NOT a retrofit. It is an essential ingredient of a retrofit, yes, but there is another ingredient (transfer ties) and very often a third (shear panels) which are also essential. If your foundation is bolted, it just means that the mudsill will probably stay put during a serious quake. The house, however, could very easily fall off the foundation. 

Be sure—have your retrofit checked.  

Make your home secure and your family safe.
