Stinger

nounShop talkConcrete

An internal concrete vibrator, or specifically the vibrating head on the end of its flexible shaft.

Shop name for the handheld vibrator crews push into fresh concrete to consolidate it. Heads run from pencil vibes about 1 in across for tight rebar to 2.5 in and larger for walls and mass work. Good practice is to drop it in vertically, let it sink a few inches into the previous lift, hold it until the surface goes glossy and pull it out slowly, never using it to drag concrete sideways.

Heard on the job

Get the stinger in every two feet along that wall and quit using it to push the mud down the form.

Insider tip

Laying a running stinger against the rebar or the form face shakes paste loose and can mark an architectural wall.
