Post-Tension Concrete
POST-TENSIONED CONCRETE SLABS & BEAMS
Post-tensioned concrete uses high-strength steel tendons (cables) running through the slab or beam that are stressed (tensioned) after the concrete has cured. The compression from the tensioned cables reduces cracking, allows longer spans between supports, permits thinner slab sections, and improves overall structural performance. We install post-tension systems for commercial slabs-on-grade, elevated decks, parking structures, and residential foundations in expansive soil areas.
Key Highlights
Compressed concrete
steel tendons compress the concrete, dramatically reducing cracking.
Longer spans
post-tensioning allows thinner slabs spanning farther between supports.
Crack-free performance
compression offsets tensile stresses that cause concrete to crack.
Why Choose Our Post-Tension Concrete
Post-tensioned concrete is the premium structural system for slabs, beams, and parking structures where long spans, thin sections, and crack-free performance are required. We install post-tension tendon systems, coordinate stressing operations, and ensure proper grouting for long-term tendon protection. All PT work is performed per PTI (Post-Tensioning Institute) standards.
Signs You Need Post-Tension Concrete
1. Long-span slab requirement
The structural design requires long spans between supports that conventional reinforcing can't efficiently achieve.
Our Process
Step 1 — Tendon layout
Install post-tension tendons per engineering layout before concrete placement.
Step 2 — Concrete placement
Pour concrete around tendons using methods that don't displace tendon positions.
Step 3 — Stressing
After concrete reaches specified strength, stress tendons with hydraulic jacks to design force.

FAQs About Post-Tension Concrete
Can post-tension slabs be cut or cored?
CAUTION: Post-tension slabs contain high-force steel tendons that can cause serious injury if cut. Any cutting, coring, or drilling in a post-tensioned slab requires a tendon scan (GPR) and engineering review first. Never cut into a PT slab without professional assessment.
