I gotta good phone call yesterday- the concrete guys were coming to my job.
They had a cancellation on a basement slab pour, because some plumbing was put in wrong; so, they’re going to pour the aprons on the front and back of the warehouse.
They extend out 8’ and run the length of the building.
The guys put tape down on slab and plastic on the walls to protect from splatters.
Once the mud was down, they used a screed to get it level with the forms.
These aprons are sloped away from the building so water won’t be a problem.
Next, they used a bull float- this smooths out the imperfections and pushes the aggregates down.
They hand troweled everything they could reach from the inside – it helped having these big garage door openings.
They sprayed some retarder on the surface to keep it from setting up too fast.
You can see here where they used an edger tool along the forms.
They used a square and string to snap lines then followed the lines with a groover.
The grooves create a weak spot in the concrete similar to cutting, so that when the slab cracks hopefully it will crack in the groove.
Finally, they put a broom finish on it- this gives it a finished look and adds traction so you’re less likely to fall.

Why’s it cut again? What do you mean by cracks in the groove?
concrete pouring is so satisfying
I’d get screamed at as a youngster for using a trowel on concrete that wet in Australia
Done an insane amount of concrete in my career, that was beautiful
