The Impact of Construction Vibration on Adjacent Structures
For comparison, building impact vibration levels are often noted as a single number quantifying the peak particle velocity (PPV, in in/sec or mm/sec). In order to determine the vibration level which could have occurred at a property, the vibration-inducing equipment must be identified, and the distance between the vibration source and the

What is a Concrete Vibrator? (with pictures)
If a concrete vibrator is used incorrectly on a concrete mix with a wide range of material sizes, it may cause the larger rock pieces to settle to the bottom, making the concrete weaker. In addition, the tool can push rock and gravel away from the area being shaken, causing weaker concrete paste to fill the area, which may result in instability.

What You Should Know About Vibration| Concrete ...
In internal vibration, the vibrator is immersed in the interior of the concrete and the vibratory waves carry outward to the surfaces. In external vibration, the vibration is applied to the surfaces and the vibratory waves penetrate the interior. On any construction job the vibrators should match reasonably well the concrete mix being vibrated.
