Part one of this series focused on slab preparation and sub-base installation. In the article, we learned the importance of a well compacted and smooth subgrade, as well the proper installation of formwork, jointing, vapor barriers and other reinforcement. This article will discuss the next steps to placing, finishing, sawing and curing medium to large concrete slab on grade.

Rate of placement and screeding method are baseline decisions that must be made prior to start of placement. Placing/finishing concrete is time sensitive and susceptible to environmental conditions. Ideally you want to work within an 8- to 16-hour window for place, finish and cure/saw cutting operations.
