Can different rubber tiles be layered in a sandwich?

Different rubber tiles can be combined in a layered system. Type XX tiles are available in three cushioning grades; any number can be used in any order beneath the surface tile. Each of these layers can have its own cushioning grade, density and thickness. The visible surface is formed by a type XT surface tile or another surface tile, whose density and elasticity need not match those of the tiles beneath it.

The order of the layers depends on how the area will be used and the performance required of the layered system. The layers are selected and arranged to balance shock absorption, load-bearing capacity and how point loads are spread. Two systems of the same overall height can therefore differ in load-bearing capacity, elasticity and damping.
