Non-Destructive Testing of Concrete Tanks

Structural and durability performance of concrete tanks depend on the strength and quality of concrete materials. Excessive cracking can result in leakage problems, which might be extremely dangerous to the public and environment (read more). Non-destrcutive testing of concrete tanks is a cost-effective and reliable way to keep them safe, and optimize maintenance costs.

Storage tanks can be one of the most aggressive environments for concrete. They require proper and routine inspection and maintenance. Most of these structures have very limited downtime windows during the inspection season. That is where NDT solutions can help minimize the inspection timeline and cost, and increase safety:

  • Structural evaluation of tank walls
  • Assessment of concrete durability (permeability)
  • Corrosion inspection and testing
  • Non-destructive Testing and Evaluation
    • Concrete strength
    • Structural detail (rebar spacing, cover thickness)
    • Concrete cracks
    • Sub-surface defects with one-side access

Concrete Tanks have been used for water and wastewater storage and treatment. They also shape an integral part of many industrial plants, such as chemical plants, and paper mills.

Durability Tests – Concrete Permeability

Concrete material properties plays a key role in the durability performance of the concrete tank. A dense, good quality concrete provides protection for the steel rebar, and prevents dangerous leakage of chemicals to the environment.
