sistered

Joined beam alongside

Sistered is the past tense of the verb sister, used primarily in construction and carpentry to describe reinforcing a weakened or damaged structural member by attaching an identical piece alongside it.

When a floor joist cracks or a rafter sags, you sister it by bolting or nailing a new board flush against the old one.

We sistered the rotted joists before laying the new subfloor.

The term draws on the idea of paired, identical siblings working together for support.
