Depending on your construction schedule, our team will prepare and install your new home slabs the rough carpentry is completed, the home is water tight (shingles and windows installed), and any basement underground plumbing has been installed and inspected.
Most of the flatwork stone base was installed during the foundation and backfill process. (Remember we used the conveyor to install the drainage stone and the basement flatwork stone before pouring footings and installed the garage and any stoop or patio base stone during the backfill process.) When they arrive on site, our flatwork crews will fine grade the basement slab and install the vapor barrier. The vapor barrier below the slab works with the entire foundation drainage system to keep your basement moisture free. During this same time, we will fine grade the garage slab and frame any door openings and stoop slabs.
The flatwork crew will usually order concrete and pour the basement floor and garage floor at the same time. All of our basement slabs are hard trowel finished with a finish machine. Before our crews can use the finish machine, the concrete slab must set up and gain a little bit of strength. During this time, our crews will pour the garage, finish framing any stoops, and order concrete for stoops and patios. All of our stoops and patios are broom finished.
After the slab is finished, the flatwork crew will cleanup, strip any forms, and saw cut all slabs. The saw cut controls joints are necessary to help control concrete cracking. The area and spacing of saw cutting and the depth of the saw cut depend on each slab. Concrete saw cut timing is very important and depends on several factors such as hardness, blade type, weather condition, and concrete mix design. If you start saw cutting concrete to early, you might be causing raveling, while sawing too late will result in uncontrolled cracking.
