Tile Flooring System

Abstract

An acid-resistant tile floor system for biologically clean environments. A tensile-load-bearing grid is placed on a floor substrate. A mixture of an epoxy resin and a resin set-up agent is poured over the grid. Ceramic tiles are adhesively bonded to the epoxy resin mixture. The epoxy resin mixture forms an acid-resistant barrier on the floor substrate and an uninterrupted adhesive surface for the tiles. The grid is made of fiberglass or other suitable material. The openings in the grid allow the epoxy resin mixture to flow down to the floor substrate. The set-up agent in the mixture ensures that the epoxy resin sets up completely around the grid, To form the uninterrupted bonding surface for the tiles.

1 . A floor tile system comprising:
 a floor substrate;   a tile layer; and   a bonding layer between said floor substrate and said tile layer, said bonding layer comprising a load-bearing grid and an adhesive mixture of an epoxy resin and a set-up agent, said load-bearing grid having open spaces formed by multi-directional grid members;   wherein said load-bearing grid is embedded in said mixture, such that said adhesive mixture surrounds said load-bearing grid so as to form an uninterrupted layer of said adhesive mixture directly beneath said tile layer and to form an uninterrupted barrier over said floor substrate.   
   
   
       2 . The floor tile system of  claim 1 , wherein said load-bearing grid is constructed of strands of fiber. 
   
   
       3 . The floor tile system of  claim 2 , wherein said strands are fiberglass strands. 
   
   
       4 . The floor tile system of  claim 2 , wherein said strands are carbon fiber strands. 
   
   
       5 . The floor tile system of  claim 1 , wherein said load-bearing grid is stamped from a sheet of plastic film material. 
   
   
       6 . A method of constructing a tile floor for use in industries that require a biologically clean floor, said method comprising the steps of:
 a) laying down a floor substrate;   b) placing a load-bearing grid on said floor substrate;   c) forming a barrier and adhesive layer by pouring a mixture of resin adhesive and a resin set-up agent over said grid, so as to cover said load-bearing grid; and   d) laying tiles on said barrier and adhesive layer.
