If e. g. Walls are to be built, the concrete is poured in 30 to 40 cm high layers and distributed reasonably
evenly. The vibrating bottles are mainly immersed vertically with a distance that is 8 to 10 times the
diameter of the bottle, and in the vicinity of the formwork is 1-2 times (pic. A). The vibrator is immersed
so deep that
About 1/3 of the bottle body in the already introduced lower layer is enough to ensure a good
connection between the different layers. The concrete is thoroughly “shaken off” when the surface
around the vibrator becomes shiny and no more large air bubbles break through the surface. This
usually takes 10-20 seconds. Slowly pull the vibrator back to give the concrete time to flow back into the
cavity left by the vibrator.
