Good job boys but get yourself some rubber boots. LOL. Let me know if you would like me to use your screed chairs in some of my videos this coming season. Looks like a good product. I would make sure you add a little mud when you pull it out so you don't get a small low spot. I have used Marco screed chairs in my videos.

Well, I am sort of retired. Working for City of Daytona Beach now. So, a big day is 2 or 3 trucks. A body gets old (55)and you need retirement and insurance. The majority of what I we did was residential and light commercial. Parking lots, warehouse buildings. We averaged about 90k yrds a year. An average day was 4 to 6 foundatioms and driveways. Seen a lot of big parking lots. Seen plenty of big super flats also. But, that was then.

Does it get expensive leaving the chair in the concrete?

Where can i purchase a flat bar?

Well, on my humble opinion anyone who needs a chair system to screed has no business in the business. And, 🤔 everywhere that you pull those rods and then just bullfloat over the joint will result in a crack along that line. Period, end of discussion.
