Six Steps to a Slab

The lower level exterior walls of the south addition were installed over a month ago, but the cement slab wasn't finished until today. Why did it take so long? Because there was still plenty of work to do!

An excavation crew started by digging multiple trenches. Then, plumbers got to work, taking extra care to tie together old and new sewer lines. Electricians were up next, running underground conduit through which wires will be run to power the new addition. The excavators returned to fill in the trenches and compact the soil. Next, cement masons installed blue polyethylene vapor liner to create a moisture barrier, then poured the slab. Finally, concrete finishers smoothed and leveled the floor using a variety of equipment and tools, including the walk-behind power trowel pictured above.
