(57) This invention is related to a tile floor which is resistant to chemicals and impervious
to liquids, said floor comprising a top layer of floor tiles (5), a substrate for
said floor tile layer comprising a supporting structural member, and a bonding material
layer (3) comprising bonding material which binds the floor tile layer to the substrate,
said substrate also comprising a mainly fibre based intermediate material layer (2),
on to which the floor tile layer is bonded with the bonding material, said bonding
material penetrating through the intermediate material layer within at least a part
of the areal extension of the intermediate material layer into contact with and bonding
to an underlying part of the substrate, thereby at least contributing to the bonding
of the floor tile layer and the intermediate material layer to the underlaying substrate.
This invention is also related to a method for producing such tile floors.
