PT cables are reliable, cheap, and expensive at the same time.
The purple lines in the photo? That’s PT cables we identify every day for one of our regular clients in Vancouver. As you can see, it’s a **busy slab**—lucky for the guy coring that hole for the pipe.
What is PT & Why is it Used?
Post-tensioning (PT) came from huge projects like stadiums and long-span bridges. It reinforces concrete with steel cables, making structures stronger, more efficient, and reducing costs by using less material.
The Benefits:
- Stronger, crack-resistant concrete
- Thinner slabs, saving material & space
- Longer spans without extra supports
The Problem:
But there’s a catch**—PT cables are **very expensive to repair.
- Hard to inspect once embedded
- Repairs cost thousands if damaged
- Can be hit even with a regular drill, like when pinning a light to the ceiling
The Solution:
That’s why building managers & structural engineers require Concrete X-ray**—because **it’s much cheaper than repairing a hit PT cable. We at Nova X-ray provide Digital Concrete X-raying with real-time results and proof of our job through digital X-ray images, just like a medical X-ray.
