Post-Tension Cable Detection: Why GPR is the Safer Way to Scan
When you’re coring, cutting or anchoring into a post-tensioned concrete slab, what you can’t see can hurt you. Severing a cable that’s carrying 33,000 lb of tension can compromise the entire structure and endanger your crew. That’s why forward-thinking contractors turn to Ground Penetrating Radar (GPR). At OmniVueNDT we scan slabs in two directions, interpret results on-site and hand you a clear go/no-go map so you can work with total confidence. From office towers to parking garages, our methodical GPR surveys uncover hidden cables, conduits and rebar that drawings often miss—saving time, money and lives before the first drill bit spins.
Post Tension Cable Project #1
Our dedicated concrete scanning crew performed comprehensive 3D scanning at multiple locations of the concrete slab and determined the layout of PT cables both in lateral and longitudinal directions, as well as the regular steel rebar reinforcement. We were also able to detect the location of PT anchors for further investigations and repair.
