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.
High pressure water jetting is a concrete removal technique mainly to remove deteriorated concrete, and tiles. Different from jackhammers and drill hammers, high pressure water jetting does not produce structural impact, and hence, less structure borne noise transmission, less damage to the building structure and less noise emission. It can be applied inside inhabited building.
