Service Details
Our retrofit methods allow contractors, engineers, and owners to safely modify existing post-tensioned slabs without shutting down entire buildings or relying on costly full-building shoring. From skylights and stair openings to elevator shafts and atrium cutouts, we use controlled de-tensioning, tendon relocation, and our patented means and methods to complete complex structural changes — faster, safer, and with less disruption to tenants and trades.
Service Benefits
- No-Shoring Needed:
Our patented methods eliminate the need for full slab shoring in most cases. - Maintain Schedules:
Other trades can continue working during our retrofit process, reducing delays. - Safe Modifications:
Controlled de-tensioning ensures stability during slab openings or layout changes. - Code-Compliant:
All work performed to meet IBC and PTI post-tensioning standards.
Experience and Qualifications
Post Tensioning Solutions has completed retrofit work on commercial, high-rise, mixed-use, and institutional buildings where slab modifications were required for tenant buildouts or design changes. Our PTI-certified teams have developed proprietary tools and field-proven methods to execute slab openings and layout changes safely — without large-scale shoring or tenant displacement. With decades of retrofit experience, we’re trusted by engineers and general contractors when precision and schedule matter.

Retrofit FAQs
Yes. With the right method and de-tensioning strategy, slab openings for skylights, elevators, and stairs can be done safely without compromising structural integrity.
No. Our patented methods eliminate the need for full-floor or full-building shoring in most retrofit applications, saving time, space, and cost.
We use controlled de-tensioning to safely release tension, then either re-anchor or reroute tendons depending on the retrofit layout and structural requirements.
Yes. We minimize disruption using dust control measures, efficient site setup, and non-invasive processes — allowing other trades and tenants to continue operations safely.
Absolutely. All methods meet IBC and PTI standards, and we coordinate with your EOR or structural team to ensure compliance throughout.
