Silo Construction Blogs
Silo construction has been an integral part of Marietta Silos services since 1916. Stave silos are among the types of silo construction methods that are used to create a silo that is suited for your current material handling needs. Other silo construction methods include jumpform and slipform silos.
Marietta Silos developed the technology for stave silo construction back in 1920 and is the only company today that produces stave silos at a thickness of 5 ¾" which creates added durability. Reinforcements like galvanized hoops are often used to help compress the silo walls and introduce tension for increased stability.
Stave silos utilize an interlocking technology using precast concrete blocks which enables the stave silo to manage your silo needs for years to come. Internal joints of stave silo interior and exterior walls need to be sealed using cementitious coatings which creates a smooth outward appearance when the stave silo is completed. Multiple discharge types may be used when constructing a stave silo including flat floor, cone, tunnel discharge, and side discharge.
If you're thinking about starting your own silo construction project, contact the experts at Marietta Silos. Marietta Silos brings over a century of silo construction and design experience to walk you through the steps of deciding what silo type and sizes will work best for your particular application.

Following the rise of concrete in the early 1900s, silo construction methods began to expand rapidly from silo cellars to concrete stave silo construction. This silo construction method was followed closely by the development of slipform concrete silo construction. This new concrete construction method enabled the creation of a continuous structure that was free from joints and seams.
Today, slipform concrete silos are constructed much like they were when the method first appeared. First, a custom-built form system for both the silo interior and exterior is constructed. This includes an interior work deck as well as interior/exterior finishing scaffolding. The form is supported by jack rods that are attached to hydraulic jacks. As the concrete is poured for the silo walls, the form is raised at approximately one foot per hour until the structure is finished.
Construction of slipform silos requires an around-the-clock construction schedule as the silo must be finished before construction is halted. The finished product has a smooth outer finish, thanks to the continuous pouring of the concrete silo walls. Slipform construction is usually the method of choice for concrete silos that are more than 65' in diameter, or several concrete silos need to be constructed at once.
Though silos now regularly dot both agricultural and industrial landscapes throughout North America, they have only been in use since the late 19th century. From their origins as silo cellars that were dug into the ground to the first vertical silo developed in the early 1880s, silo construction methods have changed a great deal over time.
Early tower-style silos lacked their now-signature round shape and were often constructed of either wood or stone. Structural issues with these rectangular designs, including corner air pockets that allowed for spoilage, high susceptibility to bowing from internal pressure, and susceptibility to wind damage, quickly lead to developments. Silos constructed with a round design were found to withstand pressure from stored materials better.
By the 1900s, concrete became a common construction material and opened the doors to concrete stave silo construction methods still used today. Since developing the technology used for concrete stave silos in 1920, Marietta Silos has remained an industry leader in construction, inspection, and restoration. Concrete stave silos are constructed using precast concrete blocks, or staves, that are at least 2" thick and interlock. These staves are reinforced with exterior galvanized steel hoops that provide the necessary tension to compress silo walls and ensure structural integrity.
Marietta Silos relies on more than 100 years of concrete stave silo construction experience to design and build superior stave silos. We're also the only company in the U.S. that produces staves that are 5 ¾" thick for increased durability. Concrete stave silos from Marietta Silos offer versatility and flexibility, as well as economy. We can design concrete stave silos with many discharge types, including cone, flat floor, side discharge, and tunnel discharge.
