·         Rebound hammer – measures surface strength of the concrete.
·         Ultrasonic Pulse Velocity (UPV) Test – Based on the wave propagation theory. It can be used to detect homogeneity of the concrete, presence of voids, crack and honey combs, to measure the quality of the concrete and depth of the crack.
·         Reinforcement Measurement Test – Performed as a preliminary test in order to locate rebars, to measure the exact concrete cover and to determine the diameter of the reinforcement bar.
