Country Stone Manor Northbrook – Concrete Pour
Today we’re actually pouring the concrete walls using that conveyor belt right now. It’s going to be an all-day event. We think it’s going to be around 30 concrete trucks 240 yards of concrete.

Hi, this is Tom Kenny with Scott Simpson Design Build. We’re on two sites here off of Voltz Road. Today we’re actually pouring the concrete walls using that conveyor belt right now. It’s going to be an all-day event. We think it’s going to be around 30 concrete trucks 240 yards of concrete. They’re driving the concrete trucks that usually have about 8 ½ yards in them backing up to like a hopper on this giant conveyor. The conveyor catches the actual concrete, runs up the ramp, along the conveyor belt, and drops down that tube into the actual concrete formwork. There’s a guy who’s actually running the conveyor location like a remote control joystick. You can actually manipulate where the conveyor goes from the field.
One of the things I like about watching this process is the way the guys just walk on top of the formwork. The formwork’s only and a half inches wide. They walk back there, they step over the lines, they pull the vibrator in and out. So they do it as if they’re walking on a flat plane. It’s a very high-level skill that you know that they’ve been doing a long time. I’d be up there like this.
They’re mixing the concrete up, you know, to vibrate the air out of it. But there’s another guy inside and he’s banging on the formwork to cause, to agitate the concrete to actually settle into the formwork. By tapping that, it causes the concrete, the cream of the concrete to go up against the formwork. It takes usually 28 days for concrete to come up to construction strength. But we’re going to take two weeks, let it get really, really hard, and then we’ll come in and start pulling all this dirt and just pushing it back up against the wall in the areas that don’t have hardscaping or driveway, because this soil, will actually settle over time and we want to use gravel in the areas that are going to be hardscaped. It could take years before it fully settles.
