    Concrete Removal

Handheld or excavator mounted concrete breaker is a traditional mechanical equipment for concrete breaking and removal. Using such equipment will generate loud noise, with sound power levels generally range from 108 dB(A) to 122 dB(A). Nowadays, a number of commercially available quieter equipment or methods for concrete breaking or removal could be less noisy or could reduce the noise propagation. These include high pressure water jet system, handheld concrete crusher, medium duty breaker, blade saw, wire saw and noise enclosure.

Quieter Type Wire Saw or Diamond Wire Saw

Wire-sawing is a flexible sawing technique that can be applied under various situations with excellent cutting performance. It can be used to cut large area and remove heavily reinforced concrete, such as towers and bridge sections. It can also be used to cut concrete in a confined workspace or even inside an inhabited building without causing much disturbance. Quieter type wire sawing or diamond wire sawing operates very fast and only emits low level of noise.
