Technical news, insights, and structural engineering advice
A single post-tension tendon replacement in Dallas can run $800 to $3,500. The real cost driver is late detection. Learn how chloride penetration works and when to act.
Poorly placed anchorages in a post-tension slab don't just create uneven stress distribution — they can eliminate punching shear benefits, reduce tendon drape, and turn a straightforward stressing operation into a costly field correction.
Drilling into a post-tension slab without locating the tendons first is not a calculation risk — it is an immediate structural hazard. A single severed tendon releases up to 33 kip of stored force instantly.
A post-tension slab is not unconditionally more earthquake-resistant than conventional RC. The answer depends on seismic zone, structural system, and detailing. We break down ACI 318-19 requirements and field realities to help you choose the right system.
Spotting a failing post-tension slab early is everything. We walk through the visible signs of cable failure, from blowouts and directional cracking to hidden corrosion, plus our field-tested inspection method and when a sign means stop work now.
Cutting into a post-tension slab without proper preparation can sever live tendons stressed to over 25 kips — triggering structural failure. Learn the 5 critical mistakes contractors and homeowners make, and how to avoid them.
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.
