Helicopter concrete

A concrete screed achieved mechanically with a helicopter, also called rotary or mechanical trowel, smooths the fresh concrete on the ground or a fresh screed before its complete plug. Through the use of the helicopter, you are going to get a very smooth surface, perfectly primed to be tiled or receive the waxed concrete finish and varnish. Ideal to make screeds on large external as internal surfaces. After a concrete realized by the helicopter, use the finish varnish of Harmony Béton to be applied to the roller."
