Dive inspections allow for underwater evaluation of interior wet surfaces and submerged conditions when taking the tank out of service is not practical. These inspections help identify coating deterioration, sediment conditions, corrosion, and other signs of wear below the waterline.

Dry inspections allow for a more complete and detailed interior assessment when the tank can be taken offline. This process provides full access to interior surfaces, structural components, roof systems, floors, and appurtenances for a thorough evaluation.

Exterior coatings are your tank’s first line of defense against the environment. Our inspections evaluate coating condition, weathering, adhesion loss, rusting, and visible deterioration to help determine maintenance priorities and future coating needs.

STS can assess the condition of existing coating systems and provide an estimate of remaining service life to support future budgeting and maintenance planning. This helps owners make informed decisions before coating failure leads to more extensive rehabilitation costs.

Ultrasonic testing is used to measure the thickness of steel tank bottoms and identify corrosion occurring on the underside of the tank. This process helps determine the amount of section loss and can reveal hidden deterioration before leaks or failures occur.

A sound foundation is essential to long-term tank performance. Our inspections review signs of settlement, cracking, erosion, movement, drainage issues, and other conditions that may affect the structural stability of the tank.

Steel loss measurement helps identify thinning plates and structural deterioration that may compromise tank integrity. By documenting material loss early, owners can address concerns before they develop into leaks, overstress conditions, or structural failure.

STS evaluates tank security and access points for vulnerability, including exterior ladders, roof hatches, roof vents, overflow piping, and other entry points. These reviews help owners improve site security and reduce unauthorized access risks.

We inspect and evaluate critical operational components to verify proper function and identify maintenance issues. This may include items such as liquid level indicators, sample tap level gauges, vents, nozzles, access systems, and other tank accessories.
