Column Repair
and Confinement
Reinforce and stabilize columns with advanced
carbon fiber confinement solutions
In the first image, we see a column suffering from severe deterioration. The concrete has cracked and spalled, exposing the reinforcing rebar to the elements. This exposure leads to corrosion, further weakening the structural integrity of the column. Such damage is a clear indicator that immediate intervention is required to prevent potential structural failure.
The second image depicts the column after the initial patching process. Our experts meticulously repair the damaged concrete by removing loose material, treating the corroded rebar, and applying a high-strength repair mortar. This step is crucial to restore the column's shape and provide a solid foundation for the next phase of reinforcement.
In the final image, the column is wrapped with SRS 660 Bi-Directional carbon fiber. This advanced material is applied using specialized epoxy resins, creating a strong, cohesive bond with the repaired surface. The carbon fiber wrap significantly enhances the column's load-bearing capacity, providing exceptional strength and durability. This method not only reinforces the column but also protects it from future damage and corrosion.
From cracked to coated: restoring concrete columns with carbon fiber and aesthetic coating
On columns where both vertical and horizontal strengthening is required but the bidirectional does not provide a sufficient increase in the capacity, two layers of the SRS-600UNI can also be used and will provide increased capacities for the component. Various coatings can be applied, depending on the desired finish once the column is reinforced and strengthened.
Types of column failure: Understanding the causes and importance of timely intervention
Concrete columns are essential structural components that bear loads and provide stability in buildings and infrastructures. Despite their critical role, concrete columns can fail due to various factors. Understanding these failure modes is crucial for preventing structural damage and ensuring safety.
Buckling occurs when a column deforms or bends under compressive forces, leading to a sudden sideways failure.
Compression failure happens when the material of the column is crushed under excessive load.
Shear failure occurs when the column's material fails along a plane due to shear stresses, causing a sliding failure.

Importance of addressing fire-damaged columns
Fires also pose a significant risk to the structural integrity of support columns, when exposed to intense heat, the materials that make up these columns can be severely compromised, leading to potential catastrophic failures.. The rapid increase in temperature during a fire causes the materials in the support columns to expand. As the fire is extinguished and the structure cools, these materials contract. This cycle of expansion and contraction can lead to cracking and weakening of the columns. Steel, commonly used to reinforce concrete columns, loses its strength and stiffness at elevated temperatures as well.
To address columns that have been compromised due to fire, carbon fiber can be applied to the damaged areas. Once the material has cured the column can then be coated in a fire-resistant coating, ensuring the column remains robust and durable in the face of further hazards.
