Archatrak fixed height support pads are typically used to support porcelain or concrete pavers where deck heights are less than approx. 1", the lowest workable height of most adjustable height plastic deck supports. The solid rubber construction of Archatrak stackable fixed height pads offers superior sound absorption, enhanced shock protection and much greater slip resistance between both pavers and pads and pads and concrete, than plastic pads. Inbuilt spacer tabs ensure fast installation and guarantee precise spacing and alignment of the pavers. Spacer tabs that are not required can be easily removed with a sharp knife. Stackable fixed height pads offer a much faster and cleaner method of laying porcelain pavers over concrete surfaces than more traditional mortar and grout installation.
