To lift the settling concrete slab foundation in your home, we first have to know where the problem is coming from. Normally, settlement of slab foundations is caused by the formation of a void or space in the ground beneath the foundation. We will fill these voids with expansive polyurethane foam and lift the slab. But first, we need to know where the voids are that need filled. To achieve this, we use Ground Penetrating Radar (GPR) technology.
Ground Penetrating radars use an antenna with high-frequency radar. This radar works with a signaling software to let us know where any underground voids or obstacles may be before we begin the concrete lifting process. There are a variety of different things that can be detected using ground-penetrating radar:
These radars are very useful for finding every sort of obstacle that we might run into while polyjacking underneath your foundation. Using this technology means that we do not have to disturb your concrete. This method also works faster than some other methods such as x-ray, as it can scan a large area in a shorter amount of time. When compared to an x-ray, a GPR is safer. It has no harmful radiation and can be used in situations where only one side of the concrete is available. A GPR also provides a real-time 3D image of what is below the concrete.
For an option to find problems beneath your slab that is safer than x-ray, will end up taking less time and less hassle, and will allow us to start the repair sooner, choose GPR services and polyjacking from PFT. Most of the GPR units in the industry can be transported easily, making them readily available for a variety of concrete and foundation repair applications. GPR also helps us stay safe by allowing us to find any dangerous obstacles, such as power lines before we start drilling into the concrete and injecting the polyurethane.
We use ground penetrating radars to assist in our slab lifting and leveling jobs, but it also is used in many other applications. GPR can be used in cemeteries, exploratory digs, streets, and even landfills. You can count on this widely used technology to help you with your settling foundation problems.
