Why post-tension decks change everything
Post-tension concrete decks — high-strength steel tendons under thousands of pounds of force
Brickell residential towers from the late 1990s forward use post-tension (PT) concrete deck construction almost universally. The decks contain high-strength seven-wire steel tendons threaded through the concrete during the pour and tensioned to 27,000+ pounds of force per tendon after curing. PT decks span longer distances with thinner profiles than conventional rebar-reinforced slabs — which is why Brickell towers can reach 60+ stories on remarkably efficient floor plates. The tradeoff: cutting through a PT deck without precise tendon mapping risks tendon failure. A severed tendon releases stored energy, can damage adjacent tendons, and in worst cases compromises structural integrity of the floor system. Every PT-deck penetration requires structural-engineer sign-off; many HOAs require ground-penetrating radar (GPR) tendon mapping before any cut.
Five-step Brickell PT-deck protocol
Every Brickell slab leak that genuinely requires PT-deck penetration follows this protocol — no exceptions.
Non-destructive detection first
Acoustic + thermal + tracer-gas pinpoint the leak source within inches before any cut is considered. The vast majority of Brickell slab leaks can be solved with PEX-A reroute through wall + ceiling cavities, avoiding PT-deck penetration entirely. Reroute is the default; PT cut is the last resort.
HOA + building engineering pre-approval
Where reroute won't work, we submit a written PT-deck access proposal to the building HOA and building engineering team. The proposal includes proposed penetration location, GPR scan results, structural-engineer sign-off, repair method, and post-repair patch specification. Pre-approval is typically 5–10 business days for non-emergency work; emergency-vendor provisions allow expedited approval for active flooding.
Ground-penetrating radar tendon mapping
GPR scan of the proposed cut zone identifies tendon paths, embedded conduits, and rebar at depth resolution suitable for precise penetration planning. The scan is documented with screenshots overlaid on the proposed cut location; we adjust the cut location if any tendon paths cross the intended access area.
Diamond-blade core drill — controlled small-diameter access
Where access is approved, we use diamond-blade core drilling with water lubrication (no impact, no vibration) to create a controlled small-diameter access hole. Core diameter is the minimum required for the repair scope — typically 3-inch to 4-inch. Cores are saved for post-repair verification; the removed concrete plug is documented and stored.
Repair + patch + post-repair verification
Repair completed through the access hole; pressure-test verifies the fix; high-strength patch grout restores the deck section using a structural-grade product matched to the original concrete strength specification. Post-repair documentation includes pressure-test results, patch product datasheet, and final inspection sign-off. Building engineering signs off before close-out.
Major Brickell residential towers we serve
We hold COI on file with all major Brickell residential towers and have established working relationships with property management at each. Vendor approval is pre-cleared for emergency response.
Four repair pathways with transparent pricing
The right pathway depends on the leak location, the surrounding system condition, and the HOA-approved penetration permissions for the building. We default to the least-invasive option.
PEX-A reroute through wall + ceiling cavities
The default approach — bypass the failed under-slab run by routing new PEX-A supply through wall chases, ceiling joists, or attic spaces. Avoids any PT-deck penetration entirely. ~92% of Brickell slab leaks resolved this way.
$1,800–$4,500GPR + diamond-core PT-deck access
Where reroute won't work, HOA-approved PT-deck access through GPR-mapped non-tendon zone. Controlled diamond-blade core, repair, structural-grade patch, post-repair verification. Includes building-engineering coordination time.
$3,400–$7,800Unit-level PEX-A repipe
Where multiple leaks indicate end-of-life supply system, full unit-level PEX-A repipe through wall + ceiling cavities. 2–4 working days for a typical 2-bedroom Brickell unit. Concierge-coordinated access throughout.
$5,800–$11,500Cross-tenant leak documentation
Leak dripping from upstairs unit into your ceiling. Detection-only documentation establishes source location; HOA + property management coordinate cross-tenant subrogation. Repair scope flows through upstairs unit owner.
