Concrete VIbrating Tips

Concrete VIbrating Tips

Vibrating is a critical step on many concrete construction projects. When concrete is poured, it might have hundreds or even thousands of air bubbles, which can substantially weaken the concrete structure. Concrete vibrators eliminate air bubbles by vigorously shaking the freshly poured concrete. Using a concrete vibrator during a pour is not only recommended; in many cases it is also a building code .
