Reinforced and post-tensioned cast-in-place slabs for hospitals, casinos, hangars, parking structures, and high-rise residential towers — engineered for clear spans, tight tolerances, and demanding loads.
Some buildings depend on concrete not just for the slab on grade — but for the structure itself. Tri-State self-performs reinforced and post-tensioned slabs, columns, beams, and shear walls for projects where clear spans, load capacity, and finish tolerances all have to work together.
Our experience with post-tensioned work covers a range of project types — from casino floor plates and aircraft hangars to high-rise residential towers and hospital patient pavilions. We coordinate closely with PT suppliers and structural engineers from shop-drawing approval through final stressing.
Structural concrete done by people who understand it isn't just a slab.
The project types where these systems are typically specified.
Patient tower slabs, surgical floors, and clear-span MRI and imaging suites that require vibration control and minimal column interruption.
Large floor plates for gaming, ballrooms, and convention spaces — clear spans that move columns out of sight lines.
Aircraft hangar floors, MRO facilities, and other clear-span environments where post-tension lets the architecture breathe.
PT slabs and balconies for residential towers, condominiums, and mixed-use developments where every floor matters.
Above- and below-grade parking decks — PT slabs for long spans, durability against deicing chemicals, and dependable performance over decades.
Classroom buildings, residence halls, and student centers where finish quality is visible and acoustic spans matter.
From flying form setup through final stressing and certification, the structural concrete scope runs under one self-performing roof.
