Industrial Silo Cleaning

Buildup, Bridging, and Ratholing

Material adheres to silo walls over time, forming crusted layers that reduce usable capacity. Bridging occurs when material forms an arch across the silo, blocking flow while leaving empty space below. Ratholing creates a narrow channel through the center while material clings to walls.

These problems reduce storage capacity by 10-40%, cause inconsistent discharge, and risk cross-contamination when switching products. Some buildup hardens and becomes structural, requiring mechanical removal.

Safe Confined Space Entry

Silo entry is classified as permit-required confined space work under OSHA and CSA regulations. Hazards include engulfment, atmospheric dangers, and mechanical entrapment. Our technicians hold confined space certifications and follow strict entry protocols.

Every job includes atmospheric testing, lockout/tagout, continuous air monitoring, and rescue standby. We use pneumatic equipment and industrial vacuums to remove material without damaging silo linings. Cleaning time depends on silo size, material type, and buildup severity.
