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.
The battery-driven fastening tool is capable of fastening cables, conduits, and installing drywall or wood tracks into concrete and steel plate. Its advantages include low recoil, dust-free and virtually no vibration. Compared to traditional hammer drills, it greatly reduces the noise impact without compromising on the productivity. Compared to gas-actuated fastening tool, changing of gas cans and cleaning of dirty cartridges are not required.
