Proleveling Wedge System from Progress Profiles is a leveling system with wedges -- ensuring improved efficiency and ergonomics, and in compliance with regulations, thanks to its fins directly fixed to the base; a patented over-tile multi-thickness multi-spacer that can be reused for cross, T-shaped and linear laying -- all in one product. Compared with traditional wedge systems, the rotation leveling system offers multiple advantages such as a considerably lower consumption of pieces, greater laying speed and no movement of tiles during laying.
