    Foundation Works

A lot of foundation works involved noisy activities, such as excavation/site formation, rock breaking and piling works. Typically, sound power levels of excavator/loader, bulldozer, excavator mounted breaker and piling machines can reach about 112 dB(A). Quieter equipment or methods are commercially available, which can significantly reduce the noise emission from the foundation works.

Non-Explosive Chemical Expansion Agent

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.
