How do I sister a joist?
As you can see (https://imgur.com/a/CHJPE), some dummies took a notch out of the center joist in my shower, and it was also damaged by water. I would like to sister it. I can't sister the entire length. The most I can access is that 3-4 foot section you see. As I understand it, I just glue the two together, then drill a hole and bolt some bolts in. Questions:
1)How many bolts should I use?
2)What size bolts should I use?
3)What type of bolt should I use?
4)What tools do i need to do this?
5)Do you guys have any other tips or anything?
Thanks a ton!
