Proleveling System is a revolutionary and innovative leveling system when laying medium and large materials with a thickness between 3 and 40 mm. The patented system is made of 2 elements: – A leveling base (1-2-3-5 mm size) with spaced notches that allow spacing/separating/ joining floors of any type and material in a way that is: linear, cross and half cross with joints to be chosen between 1 mm, 2 mm, 3mm and 5 mm. – The threaded stem is attached perpendicularly to the base in a way that allows for easy adjustment with turns of the cap during installation. Removal of the cap and Stem after the materials are set is made easy with strategically placed breakage points that release by kicking or tapping the cap in the direction of the joint. One cap fits all threaded stems and can be reused an infinite amount of times for big cost savings. The new PPLS (patented) system assists in the reduction or elimination of ledging and lippage in the installation of various types of materials that are applied to floors or walls with mortar including: Large Format Tile, Natural Stone, Thin Profile Tile and many others.
