PourDay uses the ACI 305 evaporation formula and real-time weather data to tell you whether conditions are safe to pour — before your crew ever leaves the yard.
You check the weather, make a gut call, and hope for the best. But weather apps weren't built for concrete.
High evaporation conditions accelerate moisture loss, making finishing nearly impossible and compromising the surface before your crew can work it.
When surface moisture evaporates faster than bleed water replaces it, cracks form within hours. Callbacks, repairs, and lost trust follow.
Canceling a pour last minute means idle crews, wasted ready-mix, and schedule chaos. Proactive decisions save thousands per job.
PourDay replaces gut calls with data-driven decisions in seconds.
Launch PourDay on your phone or any device. It automatically detects your location and pulls current weather conditions.
Using the ACI 305 formula and live weather data — temperature, humidity, wind speed, and concrete temperature — PourDay computes your real-time evaporation rate.
GO, CAUTION, or NO GO — a simple, color-coded answer your entire crew can understand. No interpretation required.
Every feature exists because a concrete contractor asked for it.
Real-time evaporation rate computed from current weather conditions, updated continuously throughout the day.
Built on the same evaporation formula engineers and specifiers rely on — the recognized standard in the concrete industry.
Plan pours up to 16 days out. See projected evaporation rates and status indicators for every day in the forecast window.
PourDay works for any job site in the US. Enter your zip code and get hyper-local conditions for your exact location.
Get alerted when evaporation rates are approaching or exceeding the ACI 305 threshold — before conditions turn dangerous.
Works even without cell service. PourDay is a progressive web app that caches the latest data for offline access on any device.
From ticket to finish, PourDay captures the data that protects your work and keeps your crew accountable.
Record mix details, supplier info, and ticket numbers for every load that hits your site. Build a searchable history across all your jobs.
Automatically capture weather, evaporation rate, and GO/NO GO status at the time of each pour — no clipboard required.
When a crack shows up six months later, your pour log proves the conditions were right. Documentation that pays for itself.
Export pour logs and mix records for project managers, inspectors, and engineers. Keep everyone on the same page.
