Post-Tension Systems In Naples, FL
In Florida’s demanding construction environment, post-tensioned concrete systems have become essential for managing soil conditions, controlling slab thickness, and increasing span lengths without added structural mass. At Astrum AM Structural Contractors, we provide full post-tension system installation across Naples and surrounding areas, supporting builders and engineers with precision-tensioned slabs that meet code, resist cracking, and enhance long-term durability.
Our post-tension services are most commonly used in slab-on-grade foundations, elevated decks, parking structures, and multistory buildings. Each cable, anchor, and tension sequence is installed with close coordination between our field crews, structural engineers, and city inspectors.
Engineered Post-Tension Slab Systems
Post-tensioned concrete slabs use high-strength steel tendons that are stressed after concrete is placed and partially cured. This method introduces compressive force that offsets natural tensile stress, reducing cracking and allowing thinner slab profiles.
Residential Post-Tension Foundations
Many homes in Naples are built on expansive or moisture-sensitive soils, where post-tension slabs provide additional resistance to movement. Our team installs tendon systems in residential foundations with attention to edge drop layouts, beam depths, and edge cable placement.
Commercial and Elevated Post-Tension Decks
In parking garages, podium decks, and elevated floors, post-tension allows longer spans with fewer columns. We install tendon profiles per engineering layout, securing anchors, dead ends, and edge forms before pour and stress procedures begin.
Installation Process And Field Layout
Post-tension success starts with precise field layout and material handling. Our crews coordinate tendon path layout, chair placement, and anchor location before concrete placement. This includes marking intersections, setting elevation spacers, and identifying tendon profiles as outlined in the shop drawings.
Tendon Routing and Anchor Placement
We install all components based on post-tension engineering diagrams, using curved and straight tendons depending on slab configuration. Anchors and wedges are placed in forms and secured to allow accurate stressing after the concrete reaches target strength.
Pre-Pour Inspection and Load Prep
Before pouring, all tendon installations are inspected to confirm position, tensioning path, cover depth, and security. This ensures compliance with post-tension manufacturer standards and avoids costly failures during or after stressing.
Stressing And Grouting Services
Once the concrete has reached the required compressive strength, post-tension tendons are stressed using calibrated hydraulic jacks. This step is critical in achieving the design performance of the slab. We document all stress levels, elongation data, and final securement as part of our post-tension delivery package.
Tendon Stressing Procedures
Our field techs use hydraulic jacks to pull tendons to specified tension, measuring elongation to ensure each cable is stressed according to plan. Stressing is usually completed within 7 to 14 days of the pour, depending on weather and curing time.
Grouting and Protection of Ends
After stressing, the tendon ends are trimmed and protected with grout caps, grease, or sleeves to prevent corrosion and maintain long-term durability. For elevated slabs, we provide full encapsulation of tendons to meet exposure requirements.
Integrated Structural Services
Because Astrum AM Structural Contractors performs both concrete and reinforcement services in-house, our post-tension installation integrates directly into the larger structural process. This results in faster project delivery, improved quality control, and reduced delays between phases.
Concrete Coordination
Our crews coordinate post-tension installation with concrete formwork and placement, ensuring that each step—from tendon routing to pour timing—is aligned for successful tensioning.
Rebar and Hybrid Systems
In certain projects, post-tension tendons are used alongside traditional rebar for additional support. We install hybrid systems according to engineering layouts and provide clear communication between crews working in overlapping slab areas.
