Power concrete screed

Power concrete screeds can be used in place of a man powered screed bar to strike off excess concrete. Concrete is poured from a wet mix of cement, sand, aggregate and water. Prior to the mix drying, the concrete should be smoothed out on the desired surface.

A power screed assists in the smoothing out process by leveling out and vibrating the wet mixture. Power screeds rely on small gas powered engines.
