A recent study has established some of the most advanced construction equipment. Performance and praticability of the equipment has been studied and approved on different construction sites in Hong Kong.

The data show that the sound pressure level of noise generated using quieter equipment and methods is significantly lower than that of using traditional equipment and methods

Wall Chaser

Wall chaser is used for preparing grooves on the interior walls for installation of in-wall electrical sockets, conduits, water pipes, etc. Experimental results reveal that the application of a wall chaser achieves a significant structure-born noise reduction of around 19dB(A) as compared with that of using a traditional percussive hand-held breaker. In the use of removing wall plaster, a wall chaser can be alternately used with a breaker, which can largely reduce the time of operating the breaker.
