After over a century in the silo construction, inspection, and repair industry, Marietta Silos has learned several ways to help customers save money on silo maintenance. One of the most effective strategies for maximizing maintenance budgets and minimizing downtime is coordinating essential silo services.
While regular professional silo cleaning helps protect product quality, a silo inspection completed at the same time helps ensure structural safety.
The Perfect Timing for Silo Inspections
A routine, professional silo inspection schedule is necessary to mitigate the risk of structural failure by ensuring potential problems are spotted and corrected as early as possible.
The best time to schedule a silo inspection is immediately after a professional silo cleaning. Following a comprehensive cleaning, all areas of the silo interior are fully visible to a trained silo inspector or silo engineer.
Material buildup often hides critical structural issues, such as cracking, spalling, or abrasive wear on the silo walls and roof beam pockets. By inspecting a professionally cleaned silo, inspectors can provide the most in-depth assessment possible. This proactive approach helps ensure that interior damage to areas like silo roof beams or discharge cones is caught before it becomes a major problem.
Comprehensive Care with USA Silo Service
Marietta Silos partners with its sister company, USA Silo Service, to provide seamless, end-to-end silo maintenance. USA Silo Service provides industry-leading silo cleaning services, utilizing proprietary equipment to safely and efficiently remove compacted material. Together, Marietta Silos and USA Silo Service can handle all aspects of facility maintenance, from cleaning and debris removal to expert inspection, repair, and structural maintenance.
By scheduling these services together, facilities eliminate the need for multiple mobilization fees and separate shutdown periods. This coordinated approach minimizes downtime and expense while ensuring the silo continues to operate safely and efficiently for years to come.
Marietta Silos has been a leader in concrete storage silos for over a century. While a lot has changed since we developed our concrete stave technology in 1920, the core principles of silo construction have remained remarkably consistent. However, modern engineering and shifting industrial needs have introduced several key advancements that every facility manager should know.
A Century of Evolution
In the early days of the 20th century, silos were often rectangular and built from wood or stone. These early designs were prone to structural bowing and dead spots where material would spoil or hang up. The move to round concrete structures, concrete stave silos, was a major historical leap, allowing for better management of internal pressure and material flow. Today, while the signature round shape remains, the focus has shifted from basic containment to precision engineering and structural longevity.
From Agriculture to Industrial Repurposing
One of the most notable shifts in recent decades is the decline of small-scale agricultural silos and the rise of massive industrial storage. Many older agricultural silos are now being repurposed for industrial usage. However, because industrial materials like fly ash or cement have very different storage considerations than grain or other agricultural and food materials, former agricultural silos must be professionally repurposed. In many cases, these silos require expert reinforcement and engineering to meet modern industrial safety standards.
Advancements in Discharge Hoppers: Supported vs. Suspended Cones
The design of the discharge hopper has seen a major shift toward safety. Historically, many silos utilized suspended steel cone hoppers that hang from the silo walls. However, documented failures of suspended cones have led the industry toward a more robust solution: the supported cone. By supporting the hopper from below with a reinforced concrete slab, the load is stacked and distributed through the structure to the ground, virtually eliminating the risk of catastrophic cone failure.
How a material flows through a silo is very important, as all materials flow at various rates and move through a silo differently. The material flow will determine if you need a flat bottom, cone bottom, funnel flow, mass flow, or expanded flow silo construction. Marietta Silos is equipped and experienced to handle all your silo engineering needs.
Breaking Barriers with the World's Largest Jumpform System
For decades, Jumpform silo construction was limited to silos 10 - 65' in diameter, with Slipform being the only option for larger builds. Marietta Silos has changed that. Our newly expanded Jumpform capabilities allow us to build concrete Jumpform silos up to 80' in diameter. This provides a more economical, high-quality alternative for large-scale industrial storage, offering the same strength with greater quality control during the pour.
The Digital and Protective Frontier
While construction is our foundation, we are increasingly integrating high-tech maintenance solutions that cross over into the service sector. Modern silos are now benefiting from:
- AI-Enhanced Inspections: Our supplemental AI Silo Inspection service uses drone capture and proprietary software to create a 3D digital twin of your silo. This technology can detect defects smaller than 0.1 mm, mapping their exact location and ranking them by severity to streamline budgeting and risk mitigation.
- Next-Gen Coatings: Many silos have historically suffered from leaks caused by floating membranes and other coverings that are susceptible to tearing, moisture entrapment, and failure over time. Today, advanced rubberized coatings offer a far more durable solution. These bond directly to the concrete and move with the structure's natural expansion and contraction, providing a much more resilient barrier against the elements.
Conclusion
Whether you are to utilize the world's largest Jumpform silo construction form for your next project or need to ensure your decades-old structure is reinforced for modern industrial demands, Marietta Silos combines historical expertise with the latest engineering breakthroughs. Investing in the right construction and inspection technology today is the best way to ensure the safety and efficiency of your facility for the future.

For many facility managers, an aging silo can feel like a ticking clock. When cracks appear, concrete spalls, or steel shows signs of advanced corrosion, the immediate fear is often the price tag of a total replacement.
However, at Marietta Silos, we believe the most sustainable and cost-effective path is often found through precision engineering and advanced restoration. The key is knowing what to look for before a minor issue becomes a major, and costly, problem.
At Marietta Silos, we've been restoring concrete silos for over 100 years. Here are the warning signs that tell us a silo needs professional restoration sooner rather than later.
Visible Cracking or Spalling on Concrete Walls
Surface cracks may look minor, but they rarely are. Cracking and spalling in concrete walls can signal overstress of internal reinforcing steel. If left unaddressed, that damage accelerates. Water infiltrates cracks, steel corrodes, and what started as a hairline fracture can evolve into a full structural failure. If you're seeing vertical wall cracking, exposed rebar, or chunks of concrete breaking away from the wall surface, it's time to call in a professional.
Wall Bulging or Bowing
Visible bowing of silo walls is a serious red flag. Bulging can be caused by asymmetric material flow that increases pressure along the wall, or by silos that were not originally designed for their current use. Whatever the cause, bowing walls can quickly progress to wall failure and complete silo collapse. This one should never be ignored.
Corroded or Missing Hoops on Stave Silos
For concrete stave silos, the hoops holding the structure together are critical. Corroded, damaged, or missing hoops compromise the structural integrity of the entire silo. If your stave silo's hoops are showing significant rust or are missing sections altogether, rehooping should be scheduled without delay.
Deteriorating Roof or Beam Pockets
The silo roof takes constant abuse, from overfilling, weather, and structural load. Spalling concrete around roof beam pockets is a particularly urgent warning sign, as deterioration in this area means the roof beam can no longer be properly supported, putting the entire roof at risk of collapse.
Discharge Cone Issues
Silos built with older suspended steel cone designs carry a documented high failure rate. If your facility is still operating with a suspended cone, remediation should be a priority. Cone failure can trigger complete silo failure, and there's no graceful way for that to happen.
Advanced Restoration Techniques
When a silo is structurally unsound, standard repairs aren't enough. We utilize high-level engineering interventions that can return a silo to its original load capacity, including:
- Post-Tensioning: Installing high-strength strands around the exterior to replace or supplement original steel reinforcing.
- Composite Fiber Reinforcement: Utilizing the Wabo® system to strengthen concrete and masonry without the need for heavy equipment.
- Shotcrete-Gunite: Applying high-pressure mixtures that bond 100% to cleaned concrete, offering weather and chemical resistance.
When Restoration Isn't Enough
Sometimes a thorough inspection reveals that restoration alone won't solve the problem, especially when a silo has been repurposed to store heavier materials, or when deterioration has advanced too far to remediate economically. In those cases, Marietta Silos can take you through engineering and new construction using Jumpform, Slipform, or concrete stave methods.
As the only firm in the country that handles every aspect of silo work, from design through construction and restoration, we can help you make the right call for your operation and your budget.
Don't wait for a visible failure to act. If your silo is showing any of these warning signs, contact Marietta Silos for a professional assessment. Our silo restoration experts bring decades of hands-on experience, and our team is available for emergency response when time is critical.
