Uncovering the Mysteries of Concrete Scanning

Concrete scanning is a process used to inspect concrete slabs or columns prior to drilling or boring in renovation and new construction projects. It is done with ground penetrating radar (GPR) technology, which is safe and non-invasive. The GPR unit sends radar beams towards its target, and the reflected signals are analysed to detect embedded objects. This method of imaging concrete is more effective and versatile than X-rays for concrete assessment of columns, slabs and walls.

At Slabtec, our concrete scanning services are completed using GPR technology for fast and accurate inspections. This process is invaluable in ensuring the safety of workers when building a new shop, a residential neighbourhood or demolishing an old building. Our analysts carry the GSSI Mini XT, which is ideal for locating rebar, ducts, post tension cables, voids and for determining in real time the thickness of the concrete slab. They also use the GSSI 2000 MHz palm antenna, which works in small spaces.

In addition to the GPR equipment used, all analysts are equipped with an RD 7100 unit. This unit is ideal for locating live ducts inside walls, slabs or ceilings. Scanning services can also be used to locate voids, or air pockets, between subgrade dirt and the concrete slab. ACS Underground Solutions provides services in CT, NY, NJ, MA and RI to find hidden objects or anomalies prior to concrete core drilling or saw cutting.

If you are working with concrete, you will likely have to cut or core it at some point as deterioration occurs over time. But how can you tell if there is anything in there if you can't see through it? Concrete scanning with ground penetrating radar makes working with concrete as simple as a quick scan. Before you start your next major construction project, you need to be sure that the concrete on your site is safe. GPR is an accepted and routinely used non-destructive method for imaging objects in concrete prior to cutting or coring.

When a cut is made in concrete without scanning it first, there is the possibility of encountering an underground object or hazard. We offer a selection of concrete scanning systems so you can choose the one that best suits the needs of your project. Scanning services can help guide the development of your project so you can work faster and more efficiently.

Core drilling - Concrete sawing - Ground penetrating radar - Fire protection - Thermal and moisture protection - these are all important aspects of any construction project that require careful consideration. Concrete scanning helps ensure that your project runs smoothly and safely by detecting subsurface hazards through the use of GPR.
