Ultrasonic Testing

The basic principle of this method of testing is that the velocity of an ultrasonic pulse through concrete is related to its density and elastic properties. Some care is necessary when testing, but an experienced operator may obtain a considerable amount of information about a concrete member. The advantage of this method is that the pulse passes through the complete thickness of the concrete so that significant defects can be detected. The method also determines the measurement of concrete deterioration which might have occurred due to age or through the action of fire, frost or chemical attack.

• The measurement of concrete uniformity
• Determination of the presence or absence of voids, cracks and other imperfections
• Measurement of layer thickness and elastic modulus
• Determination and monitoring of concrete strength

ELE supplies the Pundit Plus which is a fully portable instrument for assessing the quality of concrete either in-situ or pre-cast, and complies with the requirements of BS1881-203, EN 12504-4 and ASTM C597.

The lower priced Standard Pundit is also available.
