Abstract
A composite laminate surface covering member in the form of a sheet, panel or mat having an upper layer of bonded, vibration oriented, polymer granules, the upper layer being water permeable and possessing an extensive irregular channeling system formed by the voids between the granules, and a sub-layer of a closed cell polymer that is water impermeable. Additional layers for reinforcing purposes may also be present.
Claims18
A multi-layer surface covering member affixable to a substrate, said member comprising an upper layer bonded to a sub-layer;
- said upper layer composed of adhesively bonded granules, the distribution of said granules defining voids and irregular channels between the granules, said upper layer being liquid permeable;
- and
- said sub-layer composed of a closed cell polymer material, said sub-layer being liquid impermeable.
A multi-layer surface covering member affixable to a substrate, said member produced by the steps of:
- providing a form on a vibration bed;
- positioning a liquid impermeable sub-layer composed of a closed cell polymer material within said form, said sub-layer being liquid impermeable;
- forming a sludge mixture of polymeric granules and a liquid adhesive, and pouring said sludge mixture onto said sub-layer within said form;
- screeding, tamping and vibrating said sludge mixture to a desired thickness and density such that voids and irregular channels are present between said granules;
- allowing said sludge mixture to cure, such that said upper layer is bonded to said sub-layer and said upper layer is liquid permeable.
