SIPS repair

SIPS repair

SIPS repair

(OP)
Has anyone ever specified a repair for a SIP wall where the bottom 2 feet of the interior OSB has removed (flood)?  I have found splice details for vertical joints but none for horizontal joints. Thanks!

RE: SIPS repair

Although I have never detailed something like this, I can only imagine that the basic design approach is to replace the capacity of the panel with something that can transfer your in plane, out of plane and load bearing forces to a solid foundation, much like the original panel once did.

This would involve cutting away to good material (OSB) and stitching the old to new with a piece of flat blocking, much like diaphragm blocking. Your nail patterns and block'g size would be a function of the loads on the wall (lateral) panel thickness etc.

Hopefully the studs are good, since those would be a real chore to replace.

The bigger problem is probably addressing the foundation concerns. Did the flood compromise your foundation bearing material...or in other words, where did all the water go?

RE: SIPS repair

Foundation is good, the SIPS are the only issue.  My thought is to remove some foam from behind the good OSB and install a 8" strip of 1" thick OSB behind for a screwed and glued splice connection (4" for the original piece, 4" for the new piece.)  Then drill little holes at 12" o.c. e.w. and fill any remaining voids with low expanding foam.
