    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.


Non-Explosive Chemical Expansion Agent (Soundless Chemical Demolition Agent)

Unlike explosive chemicals or expansive compounds, soundless chemical demolition agents (SCDAs) do not produce vibrations, and hence, they are completely quiet and safe to use. When the chemical agent is properly used, it does not cause significant noise, ground vibration, fly rock, gas, dust or any other environmental pollution. This soundless chemical demolition agent is used for concrete demolition or rock breaking and much quieter than traditional breakers.
