Blog > Cement Pig Vs. Portable Silo
This complete guide shows you how you can plan, schedule, lease or purchase dry bulk storage for your next project.
If you’ve worked in the concrete industry, you know the cement pig. It’s been the go-to solution for on-site dry bulk storage for decades. But as job sites get faster, tighter, and more demanding, contractors are asking a simple question: Is there a better way?
The answer is yes — and it’s the portable cement silo.
In this post, we break down the real cement pig vs portable silo differences between a cement pig and a portable silo so you can make the right call for your next project.
A cement pig (also called a cement storage pig or bulk cement container) is a horizontal pressurized vessel used to store and transfer dry bulk materials like cement powder on job sites. They’re typically delivered by truck, placed on the ground, and connected to a pneumatic system for discharge.
Cement pigs have been widely used in construction for years because they’re familiar and widely available. But familiarity doesn’t mean efficiency.

With a cement pig, you stop production to refill. That downtime adds up fast on high-volume projects.
Portable silos allow you to fill and discharge at the same time, keeping your operation running continuously without interruption.
Winner: Portable Silo
Cement pigs are low-profile and can work in tight clearance situations, which is one genuine advantage. However, they’re difficult to relocate once placed and require equipment to move.
A portable silo on a hydraulic trailer can be driven to a new location, lowered, and re-deployed with minimal effort — making it ideal for fast-paced projects, remote locations, and sites where the layout changes as work progresses.
Winner: Portable Silo
Cement pigs have a lower upfront cost per unit, but that math changes quickly when you factor in crane rental, extra labor, more frequent material deliveries due to lower capacity, and production downtime.
Portable silos are available to rent, lease-to-purchase, or buy outright — giving you flexible options that match your project timeline and budget.

One of the biggest limitations of the cement pig is capacity. In the cement pig vs portable silo comparison, capacity is one of the biggest deciding factors. A standard cement pig typically holds around 20–25 tons of dry material. A portable vertical silo can hold 4 times as much, dramatically reducing the number of reloads and supply interruptions on a busy job site.

Setting up a cement pig sounds simple — until you factor in the crane required to position it, the crew needed to manage it, and the time spent waiting for that equipment to arrive. On many sites, crane availability is a scheduling bottleneck that costs real money.
A portable cement silo from Silo City arrives on its own hydraulic trailer and is raised and ready to work in under 30 minutes — no crane, no foundation, no extra crew.

Cement pigs store one material at a time with no blending capability. If your mix design calls for cement plus fly ash plus additives, you need multiple pigs and separate equipment to blend them.
A portable silo — especially the GEN 3 model — uses an engineered intake pipe angle to create a controlled cascading flow as material enters. Gravity naturally blends the materials, and the internal auger re-blends before discharge. The result is a homogenous mix ready for batching without any additional equipment.
Winner: Portable Silo
In a cement pig vs portable silo decision, there are a few edge cases where the pig still wins. We believe in giving contractors honest information. There are situations where a cement pig may still be the right tool:
Outside of those edge cases, the portable silo outperforms on nearly every metric.
Contractors who move from cement pigs to portable silos consistently report the same benefits:
