Technical articles, worked examples and field notes on post-tension slab design, tendon layout, detailing, stressing, inspection and repair.
How far can a residential post tension slab span? First-pass span-to-depth ratios, what ACI 318-19 really limits, practical span ranges and four variables that push or pull the answer.
A post tension slab cuts concrete and mild steel at once. See the CO2e math with NRMCA and CRSI benchmarks, a parking case study and where the savings stop.

A field checklist for post tension slab stressing and grouting: what to verify before the jack touches the anchor, how to read elongations, finish anchorages and grout bonded tendons.

Corrosion attacks post tension slab tendons out of sight. How it starts, a five-step inspection sequence, what drives repair cost, and the preservation steps that keep tendons dry.
Bonded and unbonded post tension slab systems fail in different places. Compare maintenance, longevity and the failure points documented in the field, from corroded anchorages to grout voids in bridges.
Post tension slab or rebar for a house on expansive clay? How each system resists soil movement, which standard really governs, and when conventional rebar still makes sense.
Estimate post tension slab repair cost by damage type and Texas region. See how the ranges were calibrated, what drives cost up or down, and when you need an engineer.
No code requires a post tension slab to be inspected after construction. Here is what a professional inspection covers, how often to schedule one in Texas, and what skipping it costs.
A severed tendon puts the load path of the whole floor in question. Follow the field repair sequence, from safety assessment to restressing and elongation check, with real Dallas cost ranges.
