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.

Wall Cutter

 

Wall cutter can be used for dismantling plaster, brick and mortar walls, as well as preparing grooves on the interior walls. A variety of interchangeable blades are available for different tasks or wall materials. Its sound pressure level at 1m is about 92dB(A). Compared to traditional hammer drills for demolition, it greatly reduces the structure-borne noise impact, minimizes the time for clearing debris and enhances the overall work efficiency.
