The Cure — my film

100 seconds on pouring concrete in salt air

The Gulf eats a rushed pour. Salt gets into the capillary pores and the steel inside rusts from the first wet tide. The cure isn't strength — it's discipline: mist the slab, keep it wet, and wait a full seven days before the first load ever touches it. Most of the trade looks for the shortcut; the slab knows the difference.

Made it myself, narrated in my own voice.

What concrete is

Concrete pour on a construction site

Concrete is a composite construction material — cement, mixing water, aggregate, and additives. Get the water wrong and it's mush that crumbles in the salt breeze; get the cure wrong and it's a ticking clock of rebar rust. Around here, everything I build answers to the same judge: the tide coming back twice a day.
