"Roller" Screed Works Concrete Up To 20 Ft. Wide MISCELLANEOUS EQUIPMENT Miscellaneous 27-6-35 Contractor Joe Churchill, Quincy, Illinois, figured there had to be a faster, easier way to screed concrete than using his old heavy vibrating power screed.
Churchill has more than 30 years experience in concrete work. He says he'd used vibrating screeds most of this time and found them too heavy, too noisy and too hard to clean.
After working on it awhile, he developed the Spin Screed. He figures his invention is the easiest-to-use power screed ever developed. It's so light one person can pick it up and load it into a truck. It consistently leaves the aggregate material just below the surface, unlike vibrating screeds that can sometimes cause the aggregate to sink too deeply into the mixture and leave the surface weak.
The design is simple. Churchill mounted one end of a length of aluminum pipe on a heavy-duty right angle drill. He mounted the drill in a specially designed T handle to make it easy to use. The opposite end of the pipe attaches to a similar T handle, so it spins freely.
To use the Spin Screed, you simply lay the aluminum pipe over the poured concrete. One worker takes each handle and the one with the power unit turns it on. Then they pull it along the surface opposite the direction the pipe spins. That way, as the pipe spins, it levels the high spots and fills the low spots in front of it. Churchill claims the Spin Screed doesn't bring excess water to the surface as it brings up the concrete paste. For this reason, he says the surface will be more durable than that created with a vibrating screed, which can bring water to the surface.
By setting the screed pipes on stakes, you can make multiple parallel passes over slabs wider than 20 ft. Churchill says the screed pipe can be set to produce crowned or swaled surfaces, in addition to flat ones.
The total weight of a Spin Screed with a 20-ft. aluminum pipe is less than 100 lbs. The motor weighs 13 lbs. and the T handles about 3 lbs. The motor and T handles will work with any length of aluminum pipe up to 20 ft., so no matter what the width of the pour, you can cut a screed to fit it.
Churchill says his simple invention has allowed his construction crews to screed concrete faster and easier, which improves both profits and morale.
Sells for $1,080, including drill. If you supply the drill and pipe, $485.
