Intra BV uses highly advanced high frequency varying vibratory hammers with varying starting points. These are so-called resonance-free vibratory hammers. High frequency variable vibratory hammers are specially developed to reduce ground vibrations as much as possible. Low frequency vibratory hammers are only suitable for use outside of built-up areas and with driving concrete and wooden poles.
