In order to meet the requirements on quality, the fresh concrete has to be processed in a professional manner. Poker vibration of concrete means that the trapped air is forced up and out through the concrete surface, consequently creating a dense and strong concrete. Our recommendations are to always poker vibrate the concrete whenever it exceeds 100 mm in thickness, or if the concrete construction is double-reinforced. The diameter of the poker vibrator is chosen according to the density and thickness of the concrete. The length of the protective tube for electrical and electronic poker vibrators respectively is 5 m, but customized lengths can be obtained if ordered.

Swepac offers both electrical and rotative poker vibrators in various diameters, as well as rotating and electronic converters.  There is also an assortment of poker vibrators with built-in converters in the product program.
