A panel assembly to be laid over a base surface and under a carpet-like top layer, the panel assembly comprising:
- a panel comprising a top face and a bottom face, the top face of the panel facing the carpet-like top layer, the panel further comprising drainage holes fluidly connecting the top face to the bottom face;
- and
- a drain mat affixed to the bottom face of the panel, the drain mat operating as a fluid-permeable layer distancing the bottom face from the base surface.
An underlayment to be laid over a base surface and under a carpet-like top layer, the underlayment comprising:
- a panel assembly comprising panels comprising edges and assembled together through their edges, wherein each one of the panels further comprises a top face and a bottom face with the top face of the panel facing the carpet-like top layer;
- a drain mat to be installed over the base surface and on which are laid the bottom faces of the panels, with the drain mat operating as a fluid-permeable layer distancing the bottom face of the panels from the base surface,
- wherein the panel assembly comprises drainage holes fluidly connecting the top face of the panel assembly to the bottom face of the panel assembly.
A panel assembly to be laid over a base surface and under a carpet-like top layer, the panel assembly comprising:
- a panel comprising a top face and a bottom face, the top face of the panel facing the carpet-like top layer, wherein the panel consists of a closed-cell structure made with closed-cell beads;
- and
- a drain mat affixed to the bottom face of the panel, wherein the drain mat operates as a fluid-permeable layer and maintains a distance adapted for fluid circulation between the bottom face and the base surface.
