CONCRETE REINFORCEMENT SCANNING

 

CONCRETE REINFORCEMENT SCANNING

When is reinforcement location needed?
During construction assessment or retrofitting it is required to determine the load capacity of old reinforced concrete structures and the original plans are not available. In this case, there are a lot of uncertainties about the concrete reinforcing steel amount, rebar diameter, depth and orientation.

Moreover, when concrete coring is required, it is not recommended to drill through steel reinforcement as this damages the structure. At the same time, the American Concrete Institute does not accept to obtain the compressive strength of cores including reinforcement as a basis to determine the compressive strength.

Covermeter: Rebar location near surface
With the correct use of the Nondestructive Technique  Covermeter, NEODEX can diagnose the type of steel in the structure.

The following benefits are offered with our service:

– Longitudinal and transverse reinforcement in slabs.
– Rebar diameter with an approximation of +/- 1 rebar number.
– Concrete coverlayer.
– Rebar location for further corrosion assessment.

GPR o Ground Penetrating Radar: Dense & detailed Rebar Location

When the reinforcing mesh is very dense, that is, if the spacing between rebars is very small, the use of the Covermeter will not give good results. In these cases it is necessary to use the Nondestructive Technique Ground Penetrating Radar GPR. After concluding our on-site GPR Testing Services, you will be provided with a Three Dimensional Reinforcement Scan (3D Scan). 3D reinforcement images are generated after processing data from scanning in 2 perpendicular directions.
