LibreOnce the truck leaves, your rebar is gone forever.
Everything that decides whether the slab holds up — rebar, chairs, anchor bolts, vapor barrier — disappears the second the pour starts. LibreCam stamps GPS, weather, and time on every photo and keeps shooting with no signal in the hole.
A pour, documented before and after the concrete hides it
The whole job hinges on a few minutes before the chute swings over.
Layout & pre-pour
- Subgrade compaction and the gravel base before forms go down
- Forms set — dimensions, alignment, and bracing in frame
- Rebar grid with spacing, laps, and chairs holding cover
- Anchor bolts and embeds placed before they're swallowed
- Vapor barrier and any under-slab plumbing, shot intact
Pour day
- Batch tickets photographed — mix, slump, time on the truck
- Placement and consolidation as the pour moves
- Conditions logged automatically — heat, cold, wind on the slab
- Control joints cut, layout and timing captured
Cure & closeout
- Curing method down — blankets, compound, or wet cure
- Finished surface, edges, and joints in good light
- Any cracking flagged and monitored over time
- Closeout set the inspector can follow stage by stage
The photos that decide whether you get paid
Concrete is the most unforgiving trade for documentation: there's no opening it back up. Once the slab sets, nobody can prove the rebar landed where the plans called for it unless someone photographed it before the chute swung over. That's the whole ballgame on a pre-pour inspection — the first thing the inspector wants is the steel in place, before any mud goes on it. Miss that window and a re-pour comes out of your pocket. The same record settles the callback a year later when a slab cracks and the GC wants to know whose fault it is. A dated photo of correct placement, the right mix on the batch ticket, and the conditions you poured in is the difference between a warranty fight and a closed file. LibreCam keeps it automatic: GPS, weather, and time on every shot, organized by job, ready to hand off as a single link backed by a pre-pour checklist.
Built for how concrete crews actually work
Pre-pour proof that outlives the slab
Rebar, chairs, anchor bolts, vapor barrier — shot before the pour buries them. The photo is the only record left once the concrete sets.
Pour-day conditions, logged
Heat and cold logged automatically on every shot. When curing is questioned, your photos already show what you poured in.
No signal in the hole? Keep shooting.
Foundations and below-grade work kill reception. Photos and captions queue on your phone and sync when you climb out.
Batch tickets on the record
Photograph the ticket with the slump and the truck time. Mix design and delivery are part of the same job, not a paper you lose.
Pre-pour checklist that matches the call
Subgrade, forms, steel, embeds, vapor barrier — work the list so nobody calls the pour with a shot missing that the inspector wants.
One link for the inspector
No app on their end. They open a browser gallery, stage by stage, wide shots for context and close-ups for the steel.
Frequently Asked Questions
Everything the concrete is about to bury: subgrade and base, forms with dimensions, the rebar grid with chairs holding cover, anchor bolts and embeds, and the vapor barrier. Wide shots to place it, close-ups to prove it. After the pour, none of it can be re-inspected.
Shoot the steel in place before any mud goes on — spacing and laps, with a tape in frame where it matters. That's the first thing the inspector checks, and the photo backs you if the call is questioned.
Yes. Photos, voice captions, and checklists all work with zero signal and queue on your phone. Everything syncs when you're back in range.
A dated record of correct placement, the batch ticket showing the right mix, and the conditions you poured in is your defense. The dispute is about what's hidden inside, and the photos are the only way to see back in.
Yes. Photograph the ticket and it lands in the same job as the placement photos, so mix, slump, and truck time are on the record instead of a slip in the truck.
Nothing. LibreCam is free for the whole crew — the free plan is the product, not a trial.
