Floor TJI wood joist in the crawl space is chewed
Floor TJI wood joist in the crawl space is chewed
(OP)
Ground water table is high and crawl space soil is wet during rain season and moist during summer time. Some of the bottom chord of the floor TJI wood joists are chewed. Is it a moisture problem or insect/animal attach? This only happens in one area of the house. If it is mfr problem then it would be all over the floor.

I would suggest installing a sump pump and replace the rat runs with TJI blocking to brace the bottom flange, or what is left of it.
Oh yea, call Truss Joist and get their recommendation for a fix for the bottom member.
Put out rat traps too.

In order to stabilize the bottom chord of open web trusses, continuous 2X4 or larger flat members are nailed to the top of the bottom chords. These 2X flat members are colloquially known as "rat runs". And it is a highway for them, especially if you have rats in the belfry.
The picture just reminded me of the application...
