Superior Walls concrete panels arrive on site with door and window openings precut according to the plans the builder supplies.
For the footing, a trench is lined with drainable geotextile filter fabric, filled with crushed stone, and roughly leveled.
The crew places the 8,000-pound panels using a crane. They establish the first corner and make sure it's plumb.
At wall corners, panels are bolted together with through-bolts.Preformed lap joints on adjacent in-line panels are fastened using a bolt and a steel fitting.
Superior Walls panels have a 3 1/2-inch-deep “rim ledge” at the inside top of the wall, completely within the wall’s exterior skin, wherever the floor system needs to bear at the exterior wall.
On this project, the Superior Walls crew set the gable end panels on the same day as the upper-story wall panels.
The underside of the 5/8-inch plywood roof sheathing is insulated with 3 inches of sprayed closed-cell polyurethane.
