What is the recommended distance to keep cables from penetration during post-tensioning?

The recommended distance to keep cables from penetration during post-tensioning is 6 inches. This standard is crucial for ensuring the integrity and safety of post-tensioned concrete structures. Maintaining this distance helps to prevent damage to the tendons, which could lead to compromised structural performance or failure.

Additionally, keeping a sufficient distance allows for proper placement and tensioning of the cables, ensuring they are fully encased in concrete where they can perform their intended role effectively. The 6-inch guideline is also based on best practices in construction to minimize risks associated with accidental puncturing or exposure of the cables during subsequent construction activities or environmental effects. This distance provides a margin of safety and contributes to the overall durability of the post-tensioned system.
