Frequently Asked Questions
What types of monolithic domes does Structure Dome Restoration service? Structure Dome Restoration services virtually all types of monolithic concrete domes, regardless of their original construction method or current use. This includes domes used for industrial bulk storage (fertilizers, cement, grains, aggregates, etc.), commercial facilities, manufacturing plants, schools, auditoriums, sports arenas, and public works. We address MRO (Maintenance, Repair, and Operations) needs for the dome shell, exterior coatings, interior linings, and insulation systems.
How often should my monolithic dome be inspected? We recommend a professional inspection of your monolithic dome exterior at least every 3-5 years, depending on its age, environmental conditions, and usage. Interior inspections may be needed more or less frequently based on the dome’s function and any interior linings. However, dome owners should conduct their own visual checks more frequently, at least annually and after any significant weather events, to spot early warning signs like cracks, stains, or coating damage.
What are the most common problems you see with monolithic domes? The most common issues typically relate to the natural aging and weathering of the exterior protective coating. This can include cracking, blistering, or chalking of the coating, which, if left unaddressed, can lead to moisture intrusion and damage to the underlying polyurethane foam insulation. Sealant failure around penetrations (doors, vents, etc.) is also common. For industrial domes, wear and tear on interior linings due to abrasion or chemical exposure is another frequent concern.
Why is the exterior coating so important for a monolithic dome? The exterior coating is the dome’s first and most critical line of defense against the elements. It protects the polyurethane foam insulation from UV degradation, moisture, and physical damage. A healthy, intact coating is essential for maintaining the dome’s thermal performance, preventing water leaks, and ensuring the overall longevity of the structure. The dome structure itself consists of the Airform (which stays in place as the outer membrane), then polyurethane foam insulation sprayed on the inside of the Airform, followed by the structural concrete layer. The exterior coating protects this entire system.
Can you repair a leaking monolithic dome? Yes, absolutely. Structure Dome Restoration specializes in identifying the source of leaks and implementing effective, long-lasting repairs. Leaks can originate from a compromised exterior coating, failed sealants around penetrations, or other less common issues. We use advanced materials and proven techniques to restore the watertight integrity of your dome.
My dome’s interior paint/lining is peeling/damaged. Can you fix that? Yes, we provide comprehensive services for dome interior linings. Whether it’s repairing existing shotcrete, specialized coatings (like epoxy or polyurethane), or installing new lining systems tailored to your dome’s specific use (e.g., abrasion-resistant for bulk storage, chemical-resistant, or food-grade applications), we can restore the protective and functional qualities of your dome’s interior.
How does Structure Dome Restoration minimize disruption during repair work? We understand that operational continuity is critical, especially for commercial and industrial domes. Our project management team works closely with you to develop a work plan that minimizes downtime. This can include scheduling work during planned outages, phasing repairs, and employing efficient work methods to complete the project safely and quickly.
What kind of materials do you use for dome repairs and coatings? Structure Dome Restoration uses high-quality, durable materials specifically designed for monolithic dome applications. This includes advanced elastomeric coatings (like polyurea, silicone, and acrylics), spray polyurethane foam (SPF) for insulation repair, and specialized lining materials suited for various industrial exposures. We select materials based on the specific needs of your dome, environmental conditions, and long-term performance requirements.
Is it expensive to maintain a monolithic dome? Proactive maintenance of a monolithic dome is generally very cost-effective, especially when compared to the potential cost of extensive repairs due to neglect. Regular inspections and addressing minor issues promptly can prevent them from escalating into larger, more expensive problems. Investing in quality MRO services from a specialist like Structure Dome Restoration extends the life of your asset and helps maintain its performance, which is a valuable return on investment.
Why should I choose Structure Dome Restoration over a general contractor? Monolithic domes are unique structures requiring specialized knowledge and experience for proper MRO. Unlike general contractors, Structure Dome Restoration focuses exclusively on monolithic dome maintenance, repair, and restoration. Our team understands the specific materials, construction techniques, and common failure points of domes. We utilize specialized equipment and methodologies developed for dome work, ensuring higher quality, more durable repairs, and a better understanding of how to preserve the dome’s unique advantages.
My dome has developed some unusual stains or streaks on the outside. What does this mean? Stains or streaks, particularly dark ones, often indicate areas where moisture is lingering or running down the dome surface. This could be due to a breach in the coating, issues at unsealed penetrations, or even organic growth like algae or mildew in persistently damp areas. It’s an early warning sign that warrants a professional inspection to determine the cause and prevent potential underlying damage.
How can I tell if my dome’s insulation is compromised? Signs that your dome’s insulation might be compromised include noticeable changes in your ability to maintain interior temperatures, unexplained increases in energy bills for heating or cooling, or visible signs of moisture intrusion like damp spots or condensation on the interior surface. If the exterior coating is damaged, the underlying foam insulation can become wet or degraded, reducing its effectiveness. An infrared thermal inspection can also help identify insulation anomalies.
Do you offer solutions that can help manage conditions related to condensation inside my dome? While Structure Dome Restoration does not provide or manage ventilation systems (which are key for condensation control), we address critical aspects of the dome envelope that influence condensation. By ensuring the integrity of the exterior coating and the continuity of the interior insulation (which is applied to the inside of the Airform before the concrete), we help maintain a consistent thermal barrier. This helps keep the temperature of the interior concrete surface further from the dew point of the interior air, which mitigates conditions favorable to condensation. Proper ventilation, managed by the owner or other specialized contractors, is also crucial.
