Post-Tension Cable Repair in Miami & South Florida
From broken steel cables to corroded anchors — we restore post-tensioned structures across Miami-Dade, Broward, and Palm Beach County with tendon replacement, post-tension slab repair, barrier cable work, and grout injection, performed by crews trained on stored-energy systems.
When a Post-Tension Tendon Fails, the Structure Loses Strength
Post-tensioning is a form of prestressed concrete: high-strength steel cables, called tendons, run through the slab inside protective sheaths and are tensioned to hold the concrete in compression. Those cables are what let South Florida's high-rises, condominiums, and parking structures carry heavy loads on thin, long-span slabs.
That strength has a weak point. In Miami's salt air, chlorides and moisture find their way to the steel — through cracks, failed anchor pockets, and voids in grouted ducts. The strand corrodes, loses cross-section, and can break, usually at the slab edge. Because a tendon is under enormous tension, cable failure is sudden, and the lost capacity transfers to the concrete around it.
New Age Construction Group restores post-tensioning systems safely — locating and assessing tendons, replacing what has failed, rebuilding anchorages, and protecting the steel — for condominiums, HOAs, commercial buildings, and parking garages across Miami-Dade, Broward, and Palm Beach County.
7 Signs Your Post-Tension System Needs Attention
Post-tension problems hide inside the slab until they surface at the edges. These are the signs our crews look for across South Florida — and with post-tensioned structures, early is everything.
Rust stains at slab edges or anchors — reddish-brown bleed at the edge of a slab or balcony often means an anchor is corroding inside.
Cracking along a cable line — cracks that run in a straight line across a slab can follow a tendon that is corroding and expanding.
Blowouts at the slab edge — concrete that has burst or spalled at the edge of a slab or balcony can indicate a failed or failing anchor.
Spalling on balconies or parking decks — surface spalling on post-tensioned elements exposes and accelerates tendon corrosion inside.
Water staining under the slab — leaks and water infiltration reaching a post-tension slab feed the corrosion that attacks the steel cables.
Cracks concentrated around anchor pockets — distress at the slab edge where the anchorages sit is a classic early sign of trouble.
Post-tension-era construction — many South Florida slabs and decks built from the 1970s on are post-tensioned and due for assessment, even without obvious symptoms.

What Is Post-Tension Cable Repair?
Post-tension cable repair restores the tensioned steel cables that give a post-tensioned concrete structure its strength. Patching the surface does nothing for the cable inside — repair means re-establishing tension safely: replacing or splicing the strand, restoring the anchorage, and returning the slab to its engineered design.
How Post-Tension Systems Fail
Failures almost always start with water. Chlorides and moisture reach the steel through a cracked slab, a failed anchor pocket, a damaged sheath, or voids in a grouted duct. Tendon corrosion eats the strand's cross-section until it breaks — often at or near the anchorage, and often without warning. South Florida's coastal exposure makes this the dominant threat to the service life of post-tensioned concrete structures here.
Our Repair Process
Every repair starts with diagnostics: GPR mapping, visual assessment, and openings at the anchor pockets where the engineer directs. Where replacement is required, we de-tension the cable safely, extract or expose the damaged strand, splice or replace it, re-stress it to the engineer of record's specification, and verify elongation. Then comes corrosion protection — regrouting ducts, restoring encapsulation, sealing anchor pockets — before we rebuild the surrounding concrete. Materials are specified for salt exposure, so the repair outlasts the conditions that caused the failure.
Safety & Engineering Discipline
A stressed tendon stores enormous energy. Cutting or releasing one incorrectly is genuinely dangerous, which is why post-tension repair is specialist work, not general concrete repair. Our crews are trained on stored-energy hazards, follow engineered de-tensioning procedures aligned with Post-Tensioning Institute (PTI) and ACI practice, and document every step — so the repair process is as defensible as it is safe.
Repair, Splice, or Replace? How the Decision Gets Made
Not every damaged cable needs full replacement — and not every cable is worth saving. The engineer of record weighs its condition, location, and role in the structure:
Re-stress or splice. If the strand is sound but an anchor failed — or a cable was nicked during coring — it can often be spliced with couplers and re-stressed to specification. Fast, contained, least invasive.
Full tendon replacement. Severe tendon corrosion or a broken strand usually means extracting the cable and installing a new one through the existing duct — restoring full design capacity.
Selective abandonment or supplemental strengthening. Occasionally the engineering favors leaving a non-critical cable and strengthening externally instead of an invasive extraction. We price and build whichever option the engineer supports.
That's why diagnostics come first: a splice and a slab-wide replacement program are very different scopes — your proposal should reflect the real one.
A Failing Tendon Is a Serious Structural Risk
Post-tension problems are hidden and high-stakes. Here's what's at stake when post-tension distress goes unaddressed.

Post-Tension Repair and Your Milestone Inspection or 40-Year Recertification
If your building is three stories or taller, Florida's milestone inspection law (SB 4-D) requires a structural inspection at 30 years — 25 near the coast — and every 10 years after. In Miami-Dade and Broward, the 40-year recertification runs alongside it. Post-tensioned parking decks, balconies, and elevated slabs are exactly where these inspections find trouble: rust at anchors, spalling, cracking along cable lines.
When an engineer's report flags post-tension distress, the repair has to be performed — and documented — before the finding can be closed out. That's the work we do every week: engineered tendon repairs with the records your board, your engineer, and the building department need. And because tendon damage rarely travels alone, we coordinate the surrounding concrete restoration, structural repair, and waterproofing under one contractor, one schedule, one point of accountability.

Post-Tension Projects We're Proud Of
Post-Tension Repair Done Safely, to Engineering Standards
Post-tension repair is specialized structural work — a tendon stores enormous energy, and it has to be assessed, de-tensioned, and restored to engineered procedures by crews trained on post-tension systems. It is not general concrete repair, and the difference is a matter of safety and structural integrity. New Age performs post-tension repair to recognized post-tension and concrete-repair standards, coordinated with your engineer of record.
We document every tendon assessed and repaired, so your engineer, your board, and any milestone inspection have a verifiable record. On post-tensioned structures, that documentation is as important as the repair itself.
