Post Tension Repair/Post Tension Cable Repair and Tendon Repair Servi…

We provide professional post tension cable repair services nationwide for exposed, damaged, corroded, or failing cables that compromise slab strength and structural performance. Repairs restore cable tension, address damaged anchor points, and reinforce the slab to reduce movement and prevent further cracking. Request a quote today.

What Is a Post-Tension Cable and What Does It Do in a Concrete Slab?

A post-tension cable is a high-strength steel tendon embedded inside a concrete slab to control cracking and add structural strength. The cables stay under tension to help the slab resist soil movement, settling, and load stress.

What Causes Post-Tension Cables to Break or Fail?

Post-tension cables usually fail because of corrosion, concrete movement, water intrusion, or accidental cutting during drilling and remodeling work. Once the protective sheath is compromised, moisture can reach the steel and weaken the cable over time.

Can a Broken Post-Tension Cable Be Repaired Without Replacing the Entire Slab?

Yes, a broken post-tension cable can often be repaired without replacing the entire slab if the damage is isolated and accessible. Repairs typically involve exposing the cable, splicing or replacing the damaged section, and re-tensioning it.

What Are the Warning Signs of Post-Tension Cable Damage?

Common warning signs include slab cracks, floor movement, sticking doors, tile separation, and visible concrete lifting or settling. These symptoms can indicate the slab is no longer distributing tension correctly.

Is Post-Tension Cable Repair Different From Standard Foundation Repair?

Yes, post-tension cable repair is more specialized because the cables remain under load and require controlled tensioning procedures. Standard foundation repairs usually do not involve stressed steel systems inside the slab.

Can You Drill or Remodel a Post-Tension Slab After Cable Repair?

Yes, remodeling is possible after repair, but cable locations should be mapped before any cutting or drilling begins. Striking an active tendon can cause structural damage and create serious safety hazards.

How Much Does Post Tension Cable Repair Cost?

Post tension cable repair costs typically range between $2,875 and $11,850, with estimated pricing depending on the number of damaged or exposed cables, slab accessibility, and the extent of concrete removal and restoration required to access the repair area. Pricing can also vary based on cable location and depth, the need for post-tension stressing operations, engineering requirements, and whether finishes or structural elements must be removed and reinstated.
