Demolition of building involves large amount of concrete breaking works. Traditional excavator mounted concrete breaker is one of the most popular equipment use for building demolition, and its sound power level can achieve about 122 dB(A). However, various quieter equipment for concrete breaking and demolition can also be found in the market.
Noise reduction for some mitigation meausres for reference.
Quieter Construction Methods
Use of hydraulic concrete crusher is much quieter than using hydraulic breaker in demolition project.
Wire-sawing is a flexible sawing technique that can be applied under various situations with excellent cutting performance.
High pressure water jetting is a concrete removal technique mainly to remove deteriorated concrete, and tiles.
The Quieter Type Blade saw with higher speed and smoother balde reduces the excitation of vibration and hence the propagation of sound.
