Basement Work: February 2007

We live very close to the Hayward Fault so my first order of business after moving in was to install shear walls to ensure that the house doesn't fall off of the foundation during an earthquake.  We moved in on Sunday, January 28th and the shear walls were done by the following Sunday, February 4th.  I finished in time to see the last half of the Super Bowl.

This photo shows how not to brace your cripple walls.  The metal strap will be useless during an earthquake.

Proper shear walls consist of 1/2" structural 1 grade plywood nailed approximately every 4 to 6 inches with 10 d nails.  Each side of the house has about 16 total feet of shear wall.  The section in the photo above is 4 feet wide.

And the shear walls are not complete unless the mudsill is bolted to the foundation.  These are 1/2" diameter x 6 inch long galvanized bolts by Simpson.  Drilling the holes for these bolts is no fun at all.

Later in the month I cleared all of the trash from underneath the house.  It consisted of 400 pounds of rotting and junk timber, lots of trash, and I don't know how many pounds of broken up concrete.  Much of the work took place in very sticky mud as water has found its way under a part of the house.
