What is a Concrete Thickness Gauge?

A concrete gauge is a non destructive testing device used to measure and test the thickness of concrete slabs, tunnel linings, walls and other plate like structures. This is a must have tool for construction professionals, engineers and inspectors to ensure the quality and safety of concrete structures. The concrete thickness gauge measures the concrete without the need to drill, core, or excavate sites using ultrasonic testing making it a cost effective and efficient solution. By giving accurate measurements it helps to maintain the integrity of concrete slabs and other plate like structures to meet industry standards.

How it Works

The Concrete Thickness Gauge uses the Impact Echo principle to measure the concrete slabs, tunnel linings, walls and other plate like structures. This non destructive testing method involves applying a mechanical impact to the surface of the concrete, generating a stress wave that travels through the material. The stress wave is then reflected back to the surface where it is detected by the gauge. By measuring the time it takes for the stress wave to travel through the concrete and back the gauge can calculate the concrete thickness.

The Impact Echo principle is based on the fact that the velocity of the stress wave is affected by the properties of the concrete, density and modulus of elasticity. By calibrating the gauge to the type being tested, users can get accurate thickness measurements. Calibration ensures greater accuracy in thickness measurements. Also the gauge can detect voids, honeycomb areas, cracks and delamination, making it a must have tool for quality control and assurance in construction projects.

What is a Sonic Echo Foundation Tester to measure Concrete Slab Thickness?

Sonic Echo Foundation Tester (Concrete Thickness Gauge) is a nondestructive system for measuring the concrete slabs, tunnel linings, walls, and plate-like structures. It can take individual coating thickness measurements, high accuracy, repeatability, and thickness measurement accuracy. Using the Impact Echo principle, it can detect voids, honeycomb areas, cracks, and delamination in concrete. No invasive methods required, it’s a must-have for checking concrete structures.

Calibration and Measurement

Calibration is a must for accurate thickness measurement and accurate determinations with a concrete thickness gauge. The device supports following standards like ASTM C1383, ensuring it adheres to recognized guidelines in non-destructive testing for integrity. The device can be calibrated at a known thickness location to get the concrete velocity for the job. This concrete velocity allows the gauge to adjust to the type being tested, to get reliable and precise results. The concrete thickness gauge measures concrete thickness using the Impact Echo principle which detects voids, honeycomb areas, cracks and delamination. The device can determine concrete slab thickness in standard and thick mode, with known thickness range of 3.2” to 6‘ (81mm to 1.8m) and 20” to 6‘ (50.8cm to 1.8m) respectively. This makes it suitable for various applications from pavements to tunnel linings. The signal strength indicator ensures accurate determinations by confirming reliable readings, thereby preventing false readings and enhancing the tool’s effectiveness in various conditions.
