Interior/ partial interior renovation works at the existing building would cause noise impact to the residents at neighbouring buildings or units. Concrete/ brickworks breaking and tiles/paint removal using handheld breakers are common noisy renovation works. Sound power levels of traditional handheld breakers can generally reach 108 dB(A). Use of some smaller mechanical equipment such as mini-breaker or innovative method such as high pressure water jet for tiles/ paint removal would generate less noise during renovation works.
Sound pressure levels of traditional and quieter equipment/ method for reference.
Quieter Construction Methods
Because of the special design, this kind of diamond blade wall saw can have sound pressure level lower than the typical one at about 10dB(A).
Unlike explosive chemicals or expansive compounds, soundless chemical demolition agents do not produce vibrations, and hence, they are completely quiet and safe to use.
Wire-sawing is a flexible sawing technique that can be applied under various situations with excellent cutting performance.
The Quieter Type Blade saw with higher speed and smoother balde reduces the excitation of vibration and hence the propagation of sound.
Less vibration and impulsive noise generated by hand-held concrete crusher than jackhammer.
