Concrete psi Pounds per square inch (psi) measures the compressive strength of concrete. A higher psi means a given concrete mixture is stronger, so it is usually more expensive. Traditional concrete walls and columns tend to range from 3,000 to 5,000 psi, while 4,000 to 5,000 psi is needed for pavement.

Our concrete imaging radar service is a combination of an electromagnetic and concrete penetrating radar survey. Our first step is to locate all known utilities (within and below a concrete slab/floor/column) using electromagnetic equipment. Once the electromagnetic survey is complete, the work area is scanned using a concrete imaging radar device.
