Portland, Oregon based Earthquake Tech owner, Steve Gemmell, walks the viewer through a typical home foundation retrofit project. Homes built before 1975 require foundation retrofitting and seismic upgrades to qualify for earthquake insurance. Houses susceptible to sliding and foundation buckling can also benefit from retrofits and SR walls, or foundation reinforcements. This video takes the mystery out of a home retrofit job and also includes the occasional comedic relief from Steve. Great for casual viewing and home improvement education.
I thought FJAs don't really provide much lateral resistance. I'm surprised that FJAs are used instead of just more UFPs. Why is that?
Also for pkuroda, the UFPs come with 3" screws called SDS screws. The bolts, according to the UFP descriptions should be 5". But I guess it depends on the concrete and necessary "embedment" I think the UFPs actually require less embedment, but the literature says to use the'r 5" titen HD bolts (maybe that's just marketing)

Thank you for that.
What sizes of these you used, in order of appearance:
nails
screws UFP
1/2 in anchor length for the UFP
Length of the sill plate bolt?
Thanks again!
