Cover Depth
Measure cover depth to design and code requirements with calibrated electromagnetic equipment.
Concrete cover depth measurement from Corvus is part of our ferro scanning service. Cover depth controls the durability of every reinforced element. We measure cover to BS EN standards, log statistics across the element, and flag bars that fall short of design or code.
Built around the question being asked.
A handheld induction probe passes over the surface. As the field interacts with steel, the device records bar position, depth and diameter range. Data is logged and overlaid on a slab map. Calibration is checked on every job to keep readings within manufacturer tolerance.
For cover depth specifically, the brief drives the choice of frequency, density, and reporting style. We quote a method that fits your access window, your accuracy requirement, and the downstream use of the data.
