Abstract
An underlayment panel includes a top surface and a bottom surface. A plurality of projections define drainage channels. A plurality of drain holes arranged through the panel provide fluid communication between the top surface and the bottom surface.

An underlayment panel having a top surface, a bottom surface, and edges, the top surface having a plurality of projections that define top drainage channels, the bottom surface having a plurality of bottom projections that define drainage channels, the edges having at least one standout spacer arranged to form a gap with an adjacent panel, the gap being configured to provide fluid communication with the bottom side drainage channels, the panel further having a plurality of drain holes arranged on the panel, the plurality of drain holes providing fluid communication between the top surface and the drainage channels of the bottom surface.
An underlayment panel comprising:
- a panel section having a plurality of drain holes formed therethrough;
- a top surface configured to support at least a layer of loose infill material, the top side further including a texture that maintains the general position of the loose infill material on the top surface;
- and
- a bottom surface having a plurality of projections that cooperate to define channels suitable to permit water flow across the bottom surface, the channels being in fluid communication with the panel drain holes, the projections having tapered sides such that the bottom side channels will retain up to 25 mm of water for a slower release rate into a substrate than a drainage rate across the channels.
An underlayment panel having a top surface, a bottom surface, and four edges, the edges being configured to abut edges of similar panels, two of the edges having flanges to allow overlapping edges with an adjacent panel when the panel abuts a similar panel, the top surface having a plurality of projections that define top drainage channels, the bottom surface having a plurality of bottom projections that define drainage channels, the panel having a plurality of drain holes connecting the top surface in fluid communication with the bottom surface, the panel being made of a molded polyolefin material, the panel including at least one locking aperture enabling an interlocking connection to secure the panel together with an adjacent panel when the panel abuts a similar panel.
