When working with post-tensioned concrete, safety and precision are critical. Post-tensioned (PT) slabs are reinforced with high-tension steel cables that, if accidentally cut or damaged, can lead to major structural issues, project delays, and serious safety risks. In this context, core hole drilling Sydney stands out as the safest and most reliable method for creating openings in PT concrete. The Risk Behind Post-Tensioned Concrete PT concrete slabs are designed to handle significant loads by compressing the concrete with steel tendons after it cures. These tendons are placed under extreme stress. Damaging one can release energy with dangerous force, possibly resulting in slab failure, loss of structural integrity, or even personal injury. Even if no one is hurt, cutting through a tendon typically requires costly structural assessments, repair work, and re-tensioning. This is why any penetration, whether for plumbing, electrical, or mechanical installations, requires a high leve...
