Jumpform silo construction is a newer construction method that has been used for the last 30 to 40 years. While it is a more economical solution to silo construction, the end result is also one of the strongest construction types available.
The system relies on a Jumpform machine, or rig, consisting of a form and scaffolding system. This reusable silo framework is set up in just a few days. The system is available in a variety of diameter sizes, from 10' to 65'. Once the desired diameter is selected, the system is assembled on site. Once in place, reinforcement steel is set, quality control is checked, and the inside form is created. Concrete is then poured into this frame in a slow, controlled process in 4' tall intervals until the desired height is reached.
The ability to ensure the quality of the reinforcement steel placement and equipment before pouring the concrete directly results in a high-quality concrete silo. Once completed, the silo will retain a grid-like pattern on the exterior where the form had been in place.
What makes Jumpform silo construction so economical? In addition to the reusable frame, the incremental schedule, rather than the continuous schedule used in Slipform construction, reduces costs by approximately 20%.
- The construction process is not adversely affected by weather events. Since the silo is constructed in 4' segments, it is easy to halt construction and pick up where it left off.
- The incremental process also allows staggered delivery of construction materials. This keeps the construction area smaller.
