Ferroscan survey

Our surveyors use the Hilti PS 200 Ferroscan detection system that determines the position of reinforcement. The equipment also measures the depth of concrete cover and estimates the diameter of reinforcement in a non-destructive manner.

The ferroscan device can be used for reinforcement identification, analysis, checking concrete cover over large areas and for structural repair work. The instrument can also be used for building acceptance inspections and quality control, as well as coring and hammer drilling rebar avoidance. It is capable of combining multiple scans in a large-area view for visual presentation.

Quickscan Recordings show where depth of cover is inadequate with statistics. It automatically assembles individual image scans into large-area images that provide a comprehensive view of the reinforcement. The Ferroscan is similar to scanning for concrete cover or location with a standard electromagnetic covermeter. However the level of detail and data recording is far more advanced. On a day to day basis we still use covermeters extensively to determine concrete cover when undertaking carbonation tests and other concrete condition assessments.

BCL also extensively employ Proceq devices and GRP techniques when required.
