The StrataRise Rubbertech Levelling Ring comes in two thicknesses: either 1mm or 3mm. They have been designed to work perfectly with the Rubbertech pedestal range. The Rubbertech pedestals makes it easy to achieve the perfect flatness on the final floor, deck, or paved area. This system is easy to use and provides you with a quick, precise, and professional installation. Each support within the Rubbertech Pedestal system is made up of a threaded head section, this incorporates four spacer fins (4mm wide for either tile or paving spacing), or with a fixing flange with screw slot used for attaching the support to a wooden joist for flooring or deck construction. The spacer fins have been designed to allow for easy removal when they are no longer required. The easy to operate threaded adjustment ring makes raising or lowering the support much quicker. It is recommended to use the optional acoustic cushioning ring for tile and paving installations, these help to bed corners securely and reduce transmitted noise through the support system. With the built-in water drainage holes, there will be no build-up of stagnant water.
