To detect underground voids, Polyjacking.com uses a Ground Penetrating Radar (GPR). GPR uses a high-frequency radar antenna and advanced signal software to accurately locate underground structures, voids, and objects.
GPR is also used for the inspection of concrete walls, structures, and slab on grade to detect embedded utilities, conduit, PVC, rebar, and tension cables. This allows for accurate diagnosis of concrete problems with time and money-saving assessments before construction and alteration of existing concrete.
This helps contractors avoid costly and potentially dangerous mistakes, like cutting utilities or rebar.

When it comes to void detection, GPR is the go-to tool for many concrete-lifting experts. Using the radar, we can find the location of voids under your foundation without having to remove the concrete. This allows us to accurately fill the voids, lifting your concrete slab back to the original position.
The GPR is very useful in void detection since it can scan larger areas much quicker than other methods, such as X-ray units.
GPR is also used to detect subsurface geological features like rock shelves and natural obstructions before construction. GPR helps assess construction sites avoiding previously unforeseen problems that might delay work or increase costs on projects.
If a utility or electrical line is not located before drilling through the concrete slab, the results could be disastrous. Using GPR to find these hazards before the lifting process is one of the ways we strive to operate safely and effectively.
In addition to being used for foundation repair and slab lifting purposes, Ground Penetrating Radars can also be used in a wide variety of other applications, such as in cemeteries, exploratory digs, landfills, streets, etc. To learn more about how we use GPR, contact Polyjacking.com today.
