    Demolition

Demolition of building involves large amount of concrete breaking works. Traditional excavator mounted concrete breaker is one of the most popular equipment use for building demolition, and its sound power level can achieve about 122 dB(A). However, various quieter equipment for concrete breaking and demolition can also be found in the market.

Sound pressure level at 7 meters from equipment

 

Noise reduction for some mitigation meausres for reference.

Applying different mitigation measures can achieve a noise reduction of 5-26 dB(A)

 

Demolition

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.

Hydraulic Crusher for Concrete Breaking

Use of hydraulic concrete crusher is much quieter than using hydraulic breaker in demolition project.

Quieter Type Wire Saw or Diamond Wire Saw

Wire-sawing is a flexible sawing technique that can be applied under various situations with excellent cutting performance.

High Pressure Water Jetting

High pressure water jetting is a concrete removal technique mainly to remove deteriorated concrete, and tiles.

Quieter type Blade Saw

The Quieter Type Blade saw with higher speed and smoother balde reduces the excitation of vibration and hence the propagation of sound.

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.
