Post-Tension Concrete Cable Repair & Splicing in Scottsdale, AZ
Post-tension concrete slabs are engineered with high-strength steel cables stretched under immense hydraulic tension inside plastic sheathing. When these tendons corrode from moisture exposure, snap due to soil movement, or are accidentally severed during remodeling core drilling, the slab loses its structural compressive strength. Our certified post-tension specialists locate, splice, and re-tension damaged cables safely.
Certified Post-Tension Tendon Restoration
Post-tension cable repair requires specialized equipment and rigorous safety protocols. A severed cable holds thousands of pounds of potential energy. We utilize ground-penetrating radar to map cable trajectories, excavate precise breakout pockets, install certified structural splicing couplers, and restress tendons to engineered tension specifications.
Tendon Breakout & Structural Splicing
Installing certified barrel couplers to rejoin severed or corroded 0.5-inch steel cables.
Hydraulic Re-Stressing to Engineered Load
Calibrated multi-ton hydraulic tensioning jacks pulling tendons to design elongation.
Grease Encapsulation & Pocket Grouting
Injecting corrosion-inhibiting grease and patching pockets with high-strength non-shrink grout.

Why Post-Tension Slabs Dominate Scottsdale
Because of Scottsdale's expansive smectite clay soils, post-tension slab foundations became the standard construction method in the 1990s. The tensioned steel cables tie the entire concrete slab into a rigid raft, allowing it to float over shifting soils. However, when a cable snaps or is cut, the structural integrity of the entire raft is weakened.
How the Post-Tension Cable Repair Process Works
A clear, disciplined 5-stage progression from initial phone dispatch to certified project sign-off.
GPR Sub-Surface Cable Mapping
Scanning concrete with radar to trace cable routing and identify exact break points.
Precision Concrete Pocket Chipping
Chipping small 6x12 inch access pockets along the damaged cable path without cutting neighboring steel.
Structural Splice Coupler Installation
Securing new seven-wire strand with certified double-wedge splice barrels.
Hydraulic Monostrand Re-Stressing
Calibrated hydraulic jacks pull the spliced tendon to engineered tension specifications.
Corrosion Encapsulation & Patching
Injecting protective grease, trimming excess cable, and sealing pocket with non-shrink structural grout.
Homeowner Preparation for Cable Repair
- ✓ If remodeling, inform your flooring contractor or plumber to cease cutting immediately until cables are mapped.
- ✓ Provide unobstructed access to exterior foundation edges where cable anchor pockets are located.
- ✓ Ensure all pets and family members stay clear of the work area during live hydraulic tensioning.
Post-Tension Repair Pricing Determinants
Pricing depends on the number of severed or snapped cables, access pocket excavation requirements (exterior stem wall vs. interior floor breakout), and whether GPR scanning is required.

Frequently Asked Questions About Post-Tension Cable Repair
Direct answers to common homeowner questions regarding duration, warranties, and engineering methods.
What happens if a post-tension cable snaps in my foundation?
You may hear a loud bang resembling a gunshot. The cable loses tension, weakening the slab's ability to resist expansive soil pressures and potentially causing cracks to open across finished flooring.
Can I remodel my bathroom or move plumbing in a post-tension slab?
Yes, but you must NEVER cut or core-drill into the concrete without first performing GPR concrete scanning to locate and mark every tensioned cable trajectory.
Is repairing a post-tension cable dangerous?
It can be dangerous for untrained handymen. Post-tension tendons are under 33,000+ lbs of tension. Our certified technicians follow strict Post-Tensioning Institute (PTI) safety and tensioning protocols.
Can you repair a post-tension cable without destroying my tile floor?
In many cases, cables can be repaired and re-tensioned from access pockets chipped into the exterior perimeter stem wall without disturbing interior flooring.
Do you provide certification of cable repair for home sales?
Yes. Every completed repair is documented with structural logs detailing elongation measurements and hydraulic jacking pressures for your records and future home buyers.
