This is an Accurate way to detect reinforcement bars and mesh, to measure their cover epth and determine the bar diameter. Rebar Locator is used to perform checks after formwork is removed, for quality control.
This test is useful for the determination of concrete cover, location of embedded rebar & estimation of size of embedded rebar. The instrument is based on the magnetic technique & is calibrated for different purposes. The cover thickness is important from the point of view of estimation of initiation of corrosion. The location & estimation of bar diameter becomes useful in structures where there are no structural drawings available. Purposes are to assist in the evaluation of remedial or repair work.
