All of our inspections examine aspects known to be potential areas of failure. In general, this includes foundations, walls and roofs. For concrete silos it also includes cones or discharge configuration.
A strong foundation is integral to wall stability and the overall safety of the workplace or structure. Cracking foundations and erosion of earth around the foundation are relatively easy to identify during general inspection if above grade. Other issues, such as settlement, can only be identified through close examination by a qualified professional.
Walls are placed under an enormous amount of stress horizontally and vertically during the normal useful life of the concrete structure or silo. These stresses can result in horizontal, vertical or diagonal cracking of the concrete walls or offset stave joints in the case of stave silo construction. Cracked silo walls can indicate delamination which greatly comprises the structural integrity of steel reinforcement in the silo wall and can potentially lead to failure or collapse if not repaired immediately.
Silo discharge cones are frequently at the forefront of silo failures. Silo discharge cones are of utmost concern in being inspected for wear, weld condition and structural integrity. Silo floors, shelves and tunnels are particular areas of concern with regard to concrete deterioration as they typically involve an interface of steel and/or concrete which can draw moisture, introduce or show signs of movement relative to structure and lead to water and material leaks.
As with any structure, the roof generally receives the brunt of the physical and environmental abuse. Proper roof maintenance is needed to keep the materials within the silo safe and dry and prevent further damage to other concrete structures.
Silo roofs are subject to abuse from overfilling, explosions, vibrations and movement during silo loading or unloading and overloading, as well as environmental abuse. Buildup of excess material leaking from conveyors on top of the roof can put undue stress on the internal infrastructure and lead to roof sag which increases the risk of collapse.
