Nondestructive Evaluation of Concrete Digester Tank

Scope

FPrimeC Solutions Inc. has been engaged by Denhall Construction Inc. to perform visual inspection and Nondestructive Evaluation of Concrete Digester Tank at the Georgetown Wastewater Treatment Plan in Halton Region in ON. The concrete digester tank had several cracks on the roof slab. The main objective of the investigation was to map cracks on the concrete roof, and estimate the extent and severity of cracks using nondestructive testing methods.

The Solution

Nondestructive Evaluation of Concrete Digester Tank1- Visual Inspection

Visual condition of concrete was perfumed by FPrimeC engineers at select locations on the interior of the concrete digester tank. A light metal hammer was used to assess potential delamination and major integrity issues on the surface.

2- Nondestructive Testing of Concrete Silo

A combination of Ultrasonic Pulse Velocity (UPV), and Rebound (Schmidt) Hammer tests was used to assess quality and uniformity of concrete. Ultrasonic Pulse Velocity (UPV) was used to verify the pulse velocity in concrete, and assess concrete quality and uniformity at select areas. Moreover, UPV method was used to estimate the depth of existing cracks in the roof slab.
