原理. 當液體從喉管的破損位置滲漏時會產生獨特的聲音，於地面上應用這技術能有效清晰地找出滲漏位置，準確地找處需要維修的喉管位置。 聲學滲漏探測的測試過程.
原理. 因為破層內的空氣外熱力傳入外牆，所以剝離位置飾表面溫度會比完整位置較高，而商技術能快捷準確指出問題飾面/混凝土的位置及範圍. 這技術能成為有效的勘察方法，原因如下. 低成本. 非破損性，無需接觸表面. 節省時間. 實質數據可作證供及陳述. 客觀的勘察結果.
原理. 雷達儀發出的雷達波進入泥層，當雷達波遇到其他物質時，它會反射回雷達儀。 這勘察不單能找出金屬管，甚至非金屬物質，例如：PVC的水管及煤氣管，光纖電纜等的位置和大約的深度也能探測出來。

Ground Penetrating Radar Survey (GPRS) provides a safe and non-invasive method of conducting speculative searches without the need for unnecessary disruption and excavation. Principle. Radar surveys work by launching pulses of energy into the soil or ground. These pulses are reflected by any subsurface objects that may present.
Structure Diagnosis. Formerly, structural failure or embedded flaws can only be identified by time-consuming and costly methods such as open up test or laboratory test on extracted sample. With the cutting edge technology today, we are committed to provide a wide range of comprehensive detection services including non-destructive tests, and in ...
