A professional commercial concrete contractor demonstrates the steps involved in pouring a 27 by 32 new concrete slab with a room finish. The concrete will be six inches thick with rebar every 48 inches on its center to achieve extra reinforcement.
The initial steps involve removing all the asphalt and preparing the area before the concrete truck pours the concrete into the site to the desired level.
While this continues, several workers move the concrete around using rakes to the areas needed for balancing.
Using an eight-foot-long screed, two workers pull it at each end, which helps create a consistent level. Several workers remove the extra concrete with rakes, and immediately after that, one worker runs the bull float to make the surface smooth.
It also helps the commercial concrete contractor know the areas they have low spots to run it through and build a tail to fix it. They then wait an hour for the concrete to dry before the commercial concrete contractor resumes working the float and the Fresno on the surface to ensure the final job is smooth while rerunning the tool joints to ensure they are straight.
