If your house was built before 1950, it is indeed just sitting on your concrete foundation. IT IS NOT ATTACHED IN ANY WAY! This means that in even in a small tremor, your house can go sliding off into your driveway. The Mud Sill is the wood that rests directly on top of the foundation. Until the 1950's builders did not often bolt the mud sill to the foundation leaving it vulnerable to sliding as a result of earthquake movements.
Foundation bolting (house bolting) has been compared to a seatbelt for your house. The up-and-down and side-to-side motion of an earthquake can shake an unbolted house off its foundation. During the 1994 Northridge earthquake, thousands of unbolted homes were damaged or destroyed. Foundation bolting is easy, quick and inexpensive and provides greater protection against the forces of earthquakes.
Contractors Thousand Oaks specializes in foundation bolting and the bracing of cripple walls (short stud walls between the floor and foundation of some houses) by using structural-grade plywood which, if needed, provides greater resistance to earthquakes. These steps, along with properly tying the floor system down with approved framing anchors, will make yours a safer home.
