Field execution of PT slabs: layout, stressing sequence, elongation checks, grouting and as-built documentation.
Where anchors sit decides where a post tension slab gets its precompression. Anchorage zones, drape and balanced load, punching shear, and the layout rules we apply in the field.
Cutting into a post tension slab without a plan can sever a stressed tendon. The five mistakes we see most often, and the checklist that prevents them, for owners and contractors.
Before you core or drill a post-tensioned slab: how to confirm it is post-tensioned, how scanning locates the tendons, and the seven-step checklist we follow before every penetration.
A field protocol for post tension slab stressing: what OSHA 1926.701(c) requires, how to set the live-end zone, check the jack and gauge, load in stages and accept elongations.
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.
