Silos are unique structures, and waterproofing coatings are not created equal. Silo coatings like floating membranes and roofing tar are some of the cheapest to acquire. However, they are also the most likely to fail during the normal use of a metal or concrete silo. Membranes are easily punctured during routine loading and unloading or even through heavy foot traffic. Roofing tar, on the other hand, cannot tolerate foot traffic. Tar also naturally softens by the sun, allowing stored material to stick into the surface and create buildup that is extremely difficult to remove. In cold weather, tar solidifies and can easily crack and allow moisture to penetrate the silo and jeopardize stored material. Sprayed polyurethane coatings similarly do not tolerate foot traffic, are easily punctured and are sensitive to humidity.
The most effective, monolithic barrier against moisture is a rubberized coating that bonds directly to various surfaces to repair cracks and seal penetrations, laps and fasteners. Rubberized coatings have a high elasticity coefficient that moves with silo vibration caused by roof-mounted equipment or loading and unloading.
Our rubber coating reduces costly reapplications of surface protectants and can be applied to many surfaces. As a silo roof coating, our rubber coating can fix both metal silo roofs and concrete silo roofs. In addition, our silo roof-top coating has the flexibility to maintain its integrity through the changing seasons, protect against oxidation, humidity and corrosive environments while resisting alkali, salts, abrasions and fumes.
Rubber Roof-Top Coating Works On:
- Metal buildings and roofs
- Built-up roof (BUR) membranes
- Grain silos and bins
- Silo exterior walls
- Single-ply roofs
- Urethane foam roofs
- Steel bolted joints
- Concrete silo roofs
Additional Benefits of Rubberized Silo Coatings:
- Not a floating membrane
- Offers excellent adhesion to aluminum, galvanized steel, painted surfaces, modified bitumen, steel joints and many other surfaces
- Excellent in sealing cracks, laps, fasteners and roof surface penetrations
- Available in all 50 states and a variety of colors
Our roof-top silo coating method is a proven industrial roof coating system that keeps elements out and stored materials dry. Request a quote from us today.
Proper material flow in silos is important for more than just production schedules. Issues with material flow can cause increased stress on silo walls that may go beyond what the silo was designed to withstand. Not only does this cause cracking, spalling and possible wall separation, it can also lead to structural failure.
Silos that were initially designed with internal reinforcement sometimes face cracking or delamination of the concrete. When this is seen on the silo exterior, it is important to schedule a silo inspection as soon as possible. Such damages are often caused by overstressing of the horizontal reinforcing as a result of material flow issues.
What is silo post-tensioning?
Tension is a critical component in silo repair. If the silo is still structurally sound, certain damages caused by failing interior steel reinforcement can be repaired by post-tensioning. Post-tensioning silo repair uses high-strength post-tensioning strands that are placed around the exterior of the silo. These tensioned bands essential take over the structural support of the original internal steel by keeping walls sturdy against additional stress caused by asymmetric flow.
During this restoration process, a qualified engineer uses factors such as silo size, stored material weight and how the silo is used to determine tension specifications necessary specifications for wall reinforcement. After the strands are properly tensioned through a hydraulic process, steel lock couplers are positioned and tightened. Once completed, the tensioning assures that the silo can be safely used. Once the silo is restored through post-tensioning, it can then be returned to its actual load capacity.

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%.
Additional benefits:
- 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.
