Post-tension cables in concrete slabs have become a cornerstone for enhancing structural integrity in modern construction. These cables, known for their strength, offer significant cost savings initially and over the long term by reducing the need for materials and minimizing future repair costs. However, their strength comes with challenges, especially when damaged. Their immense lateral force can compromise the foundation of buildings and pose serious injury risks.
Do You Know the Depth of Your Post-Tensioned Cables?
Before undertaking any work on a post-tension slab—drilling, cutting, or coring—you must know the location and depth of the post-tension cables. The depth of these cables varies based on several factors, including the slab's overall thickness, when the slab was poured, and the standards used by the original contractors. This variability underscores the importance of not relying on guesses or estimates but on precise detection methods.
Ground Penetrating Radar is Key for Determining the Depth of Post-Tensioned Cables
Ground-penetrating radar (GPR) is a reliable technology for this task, providing a clear image of what lies within the concrete slab, including the tendons' positioning and depth. However, GPR is one of many concrete scanning methods. Many companies use other scanning methods, like Ferroscan, to detect and measure metal elements in concrete slabs. Ferroscan is great for determining rebar diameter and similar measurements, but GPR is the proven scanning method for determining post-tension cable depth.
