Earthquake Tech Walks You Through a Foundation Retrofit Project

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!
