Common Issues Found During Concrete Tank Inspection and How to Prevent Them

Do you want to know the common issues found during concrete tank inspection? Inspection of tanks enables you to keep the tank clean and keep the water safe from all issues. However,  concrete tanks are used across various industries to store water, wastewater, chemicals, and fire protection reserves across industrial, municipal, and commercial facilities. 

Hence, as time passes by, these structures are exposed to environmental stress, chemical reactions, hydrostatic pressure, and operational wear that can compromise their integrity. That is why concrete tank inspection is not just routine maintenance. It is a critical safety and compliance measure. Therefore, early detection of major structural issues can prevent life-threatening failures, reduce downtime, and regulatory penalties. 

Concrete tanks are often used as construction sites for storing water, and are also used at mining sites to store chemicals. However, tanks in which chemicals are stored require cleaning and maintenance. And human intervention in cleaning can be risky. 

The advancement in technology has made it easy for you conduct concrete tank inspections using Rov For Underwater Inspection and advanced Inspection Class Rov systems. These technologies have made inspections today safer, faster, and more accurate than ever before. 

In this blog, we will discuss the most common issues identified during Concrete Tank Inspection and how to prevent them. Keep reading and keep exploring! 

Prevent Costly Repairs: Key Problems Identified in Concrete Tank Inspection

Here are some of the critical issues that you find during concrete tank inspection. However, let us dive straight into the topic. Keep reading and keep exploring! 

#1.  Cracking in Concrete Walls and Floors

Concrete tanks develop cracks on the walls and floors due to movement, shrinkage, temperature, and overloading. However, cracks may seem minor at first, but over time, they become wider and riskier to everyone. Hence, these cracks give rise to problems like 

• Lead to water leakage

• Allow contaminants to enter

• Accelerate reinforcement corrosion

• Compromise structural stability

Therefore, prevention is always better than a cure. The concrete tank inspection, using ROV for underwater inspection, ensures proper curing and reinforcement during construction. It is essential to apply waterproof coatings or liners, conduct routine inspections to monitor crack width, and use sealants or epoxy injection for early-stage cracks to avoid any major issues in the future.

Inspections: Class Rov technology should be used regularly to help identify cracks in submerged areas without draining the tank, reducing downtime.

#2. Reinforcement Corrosion

Moisture and high temperatures affect the thin coating on concrete tanks. However, the steel reinforcement bars (rebar) inside concrete can corrode when exposed to moisture and oxygen through cracks or gaps in concrete structures. However, corrosion expands the steel, leading to internal pressure that causes spalling and structural weakening. Hence, fire water tank inspection is important because you cannot afford structural weakening in these tanks, as reliability is non-negotiable for fire water tanks. 

Hence, the professional experts use different prevention techniques and strategies: 

• Apply corrosion-resistant coatings

• Maintain proper concrete cover over rebar

• Control water chemistry levels

• Repair cracks promptly

Therefore, expert professionals who offer concrete tank inspection service use the Inspection Class ROV technology for a visual assessment of submerged structural components and early detection of corrosion-related distress. 

#3. Spalling and Surface Deterioration 

Spalling occurs when the surface layer of concrete breaks away due to corrosion, freeze-thaw cycles, or chemical exposure. However, this weakens the structure and exposes reinforcement. Hence, some common causes lead to spallings and surface deterioration of the concrete tanks 

• The construction quality of the tanks is poor.

• Chemical attack, especially in wastewater tanks

• Long-term water infiltration

Therefore, here are some strategies that you can use to prevent surface deterioration of the concrete tanks: 

• Use high-quality, low-permeability concrete

• Apply protective coatings

• Schedule periodic Concrete Tank Inspection
  
  

Therefore, address minor surface damage immediately to avoid future issues. Regular concrete tank inspection is one such way that can serve as a saviour for you and prevent major failures. 

#4. Leakage and Seepage

Leakage and seepage are common issues discovered by the professionals who inspect concrete tanks. However, leaks may occur through cracks, failed joints, or deteriorated seals. There are some consequences you have to face due to leakage and seepage in tanks 

• Water loss

• Soil erosion around the tank

• Structural instability

• Contamination risks

Therefore, to prevent these issues in the future, it is essential to take preventive measures like inspecting joints and seals regularly, installing waterproof membranes, and monitoring water levels for unexplained loss. There, it is better to use ROV inspections to check underwater joints. This is because humans don’t do underwater for inspections. Modern Rov For Underwater Inspection technology enables leak detection without emptying the tank, minimizing operational disruption.

#5.  Joint and Seal Failure

Do you know there are joint areas where pipe penetrations are done? However, these areas are vulnerable, and the sealing does not prove to be effective. With time, these sealants break, and harmful chemicals enter the concrete tanks. Hence, this concerns Fire Water Tank Inspection, as joint failure can compromise emergency reserves. These reserves are crucial during emergencies, and the degradation of sealants can affect the operations. 

Therefore, it is essential to hire a professional concrete tank inspection to take preventive measures, like scheduling periodic cleaning, installing inlet filtration systems, and conducting underwater surveys using ROV technology. 

Regular concrete tank inspection services ensure sediment levels are monitored before they become problematic.

#6. Chemical and Biological Attack

Often it is observed that in mining tanks and tanks in which chemicals are stored. The floor of the tanks starts to erode. However, the wastewaters and chemicals in industrial tanks, such as sulfate attack, acid corrosion, and microbial-induced corrosion (MIC), are common. However, these issues can significantly reduce the structural lifespan of the tanks, and you need to spend a lot of money on repairs and building new concrete tanks. This not only wastes time but also affects productivity. 

Therefore, it is better to use some preventive strategies to save from all the trouble in the future. Here are some preventive strategies you can take: 

• Use chemical-resistant liners

• Monitor chemical levels

• Apply protective coatings

• Perform regular inspections using Rov For Underwater Inspection
  

 Early detection prevents extensive rehabilitation costs
