    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.

Foundation Works

Noise enclosure for underground construction works

Use of acoustic enclosure for stationary plant can achieve a noise reduction up to 20dB(A) easily.

(Wilson Acoustic) Noise barrier

An effective way of reducing noise is to install a purpose-built barrier between the noisy equipment and the noise sensitive receiver.

Non-Explosive Chemical Expansion Agent

Unlike explosive chemicals or expansive compounds, soundless chemical demolition agents do not produce vibrations, and hence, they are completely quiet and safe to use.

Silent Piling by Press-in Method

Silent Piling by Press-in Method : Traditional massive augering and piling machines for sheet piling work at hard ground condition would create significant noise and vibration impacts to neighbours. 

Equipment with QPME Label

QPME or Quality Powered Mechanical Equipment items, are construction equipment items that are new, notably quieter, more environmentally friendly and efficient.

Bursting System

Bursting system can be used for concrete breaking to replace traditional handheld percussive breakers.
