Non-Destructive Testing and Scanning of a Reinforced Concrete Building – City of Toronto

Scope

FPrimeC Solutions was retained by Golder Associates Ltd. (Client) to perform non-destructive testing and scanning on concrete slabs and columns of a reinforced concrete building located in Toronto, ON. The client was interested in screening subsurface condition of concrete for potential anomalies and voids. The main objective of this project was using a combination of non-destructive testing methods for concrete mapping and scanning.

 

Solution 

Following communication with Client, a test plan was prepared and proposed to the client. The proposed solution involved two (2) major steps:

 

GPR Scanning was performed at different areas to map the distribution of steel reinforcement and live conduits.

Ultrasonic Pulse Echo (UPE) scan was performed to detect potential subsurface anomalies and voids. UPE uses shear waves to detect major voids and discontinuities in concrete.
