Abstract

There is described a panel assembly to be laid over a base surface and under a carpet-like top layer to install a multi-layered sports-playing field. The padding assembly comprises a panel comprising a top face and a bottom face, with the top face of the panel facing the carpet-like top layer and the panel further comprising drainage holes fluidly connecting the top face to the bottom face. The padding assembly also comprises a drain mat affixed to the bottom face of the panel with the drain mat operating as a fluid-permeable layer distancing the bottom face from the base surface. A method of installing a multi-layered sports-playing field is also described.
