Concrete Thickness Gauge: Sonic Echo Foundation Tester
What is a Concrete Thickness Gauge?
A concrete gauge for thickness 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 thickness of concrete without drilling, coring or excavating 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 thickness of 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 of concrete being tested, users can get accurate thickness measurements. Also the gauge can detect voids, honeycomb areas, cracks and delamination in the concrete, making it a must have tool for quality control and assurance in construction projects.
