Silo Post-Tensioning

Vertical silo spalling, cracking or wall separation due to overstress of the horizontal reinforcing are the main symptoms repaired with post-tensioning—a very common problem. To solve this issue, Marietta Silos will install high-strength post-tensioning strands around the wall exterior. These strands can replace all of the original steel reinforcing and, assuming the concrete is still sound, the silo can be returned to its original load capacity in an economical manner.

Silo Roof Repair

As with any structure, the roof of the silo generally receives the brunt of the physical and environmental abuse. Proper roof maintenance is needed to keep the materials within the silo safe and dry. Roofs are subject to abuse from overfilling, explosions and overloading, as well as environmental abuse.

Marietta Silos uses a variety of techniques to replace, repair or modify your silo roof so it can continue to meet your needs. Learn more about Maintaining Silo Roof Structure and Integrity

Silo Rehooping

Marietta Silos has vast experience in rehooping concrete stave silos, whether they store foundry sand, lime, clay, cement, grain products, or have been adapted for industry use. Older stave silos often have hoops that are corroded, damaged or missing altogether. In order to maintain the structural integrity of the silo, removing unsound hoops and/or replacing hoops with a full complement of new steel hoops may be necessary. If only a few hoops need to be repaired or replaced, Marietta Silos can do that too.

Rehooping can ensure your older stave silos regain or maintain their full storage capacity. A special waterproof coating may be applied after rehooping to ensure the long-term durability of the hoops.

Gunite Patch on Concrete Silo

Gunite is a mixture of sand, cement, and water, which is applied with air pressure. Not only is it as strong as poured concrete, it is also very resistant to weather and chemicals and bonds 100% to well-cleaned concrete.

The satisfactory application of gunite is not for the layman. Fortunately, Marietta Silos has the experience necessary to complete the job to your satisfaction.
