Technical news, insights, and structural engineering advice
We compare post-tension slabs against conventional RC for high-rise construction. From structural depth and load balancing to formwork cycles and schedule savings, here is where each system wins and where each falls short.
When architecture demands a column-free cantilever, reinforced concrete runs out of answers fast. Here is how post-tension slab design makes the structurally impossible commercially viable.
Once concrete is poured, the stress state of a post-tension slab becomes invisible. IoT-embedded sensors change that — delivering continuous tendon performance data from inside the slab to your engineering dashboard.
When a post tension slab gets ruled out, most teams default to conventional reinforced concrete without running the numbers. We break down what that substitution actually costs — and when steel or precast is the smarter call.
A severed post-tension tendon releases up to 26 kips of prestress force instantly. The first 24 hours determine whether you face an $850 splice repair or a $15,000 structural investigation. Here is the exact protocol we follow on-site.
Parking garage design pushes conventional RC to its limits. A post tension slab cuts slab depth by nearly half, extends bay spans past 60 ft, and recovers clear height floor by floor.
Drilling into a post-tension slab without locating the tendons first can sever a cable under 30 kip of force. This checklist walks you through the exact protocol to find and avoid them safely.
We compared a post tension slab against a standard RC design on a Dallas commercial floor plate. The PT system used 34% less concrete and significantly less rebar. Here is what that difference looks like in pounds of CO2e.
Stressing a post-tension slab carries jacking loads exceeding 33 kip per strand. One procedural failure at the live end can trigger anchor blowout, rework costs, and schedule delays. Here is the code-backed safety protocol your crew must follow.
Most owners ask whether PT slabs are worth the premium. That's the wrong question. The real question is where the value lands — and how to quantify it before the project breaks ground.
Expansive clay soils in Dallas can heave and shrink enough to crack a conventional slab within years. We break down how a post-tension slab maintains compressive prestress across all soil movement conditions — and what detailing decisions actually hold up on-site.
Post-tension slab repair costs vary widely — from $3/sq ft for surface crack sealing to over $3,500 per fractured tendon. We break down real Texas project cost ranges by damage type, so you can budget with confidence.
