    Quieter Construction Methods

Some advanced quieter construction methods have been established. Performance and practicability of the equipment has been studied and approved on different construction sites in Hong Kong.


High Pressure Water Jetting

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.
