It is important to scan any foundation before you work on or around an edifice. It is also a good idea to check the foundation of a home you plan to occupy. A floor can look flawless on the surface, but there can be cracks and holes beneath the surface of the concrete. For your safety, it is best to perform a concrete scan so you can know the condition of the establishment in question.
A slab scan in Sydney will allow you to collect data without tearing into the ground unnecessarily. Professionals use Ground Penetrating Radar (GPR) to survey the foundation very quickly and accurately. The X-ray technology peers into the surface and delivers the results on a clear 2D projector. Even if the professional is on the jobsite, they can perform this scan without disturbing any worker or arrangement.
Checking the status of a foundation will definitely put your mind at ease. Performing this task is far better than guessing and taking chances.
