Abstract
Abstract An improved terrazzo floor or wall construction of reduced thickness bonded and adhesively secured to an underlying sub-surface through the medium of an intermediate liquid impermeable sheet. A frangible terrazzo veneer is bonded to the liquid impermeable sheet and the sheet in turn is adhesively secured to the underlying sub-surface by a rubberized asphalt or the like elastomeric material to permit lateral movement of the sub-surface relative to the said facing veneer to obviate cracking of the veneer due to cracking or lateral movement of the sub-surface.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
91 words
In combination, a sub-surface, a sheet of flexible pre-manufactured liquid impermeable material, an elastomeric adhesive securing said sheet to said sub-surface, a frangible thin facing veneer, and a bonding agent securing said facing veneer to said liquid impermeable sheet, said bonding agent compatible with said sheet material and with said facing veneer whereby said facing veneer is rigidly secured to said liquid impermeable sheet, which facing veneer is applied in the form of a wet slurry mix, said elastomeric adhesive permitting lateral movement of said sub-surface relative to said facing veneer.
Claim 2
Dependent Claim
91 words
In combination, a sub-surface, a sheet of flexible pre-manufactured liquid impermeable material, an elastomeric adhesive securing said sheet to said sub-surface, a frangible thin facing veneer, and a bonding agent securing said facing veneer to said liquid impermeable sheet, said bonding agent compatible with said sheet material and with said facing veneer whereby said facing veneer is rigidly secured to said liquid impermeable sheet, which facing veneer is applied in the form of a wet slurry mix, said elastomeric adhesive permitting lateral movement of said sub-surface relative to said facing veneer.
Claim 3
Dependent Claim
34 words
A structure according to claim 1 wherein said sheet of liquid impermeable material is polyethylene or polyvinyl chloride and the side to which the facing veneer is bonded is abraded to roughen surface texture.
Claim 4
Dependent Claim
25 words
A structure according to claim 2 wherein said bonding agent is selected from the group consisting of an aqueous resinous latex emulsion and epoxy resin.
Claim 5
Dependent Claim
62 words
A structure according to claim 1 in which the sheet material is polyethylene, the side to which the facing veneer is bonded is abraded to roughen the surface texture, a contact cement is applied thereto, and the sheet material containing the said contact cement is heated to the softening temperature thereof for intimate bonding of the contact cement to the sheet material.
Claim 6
Dependent Claim
28 words
A structure according to claim 1 in which the sheet material is polyvinyl chloride and a porous fabric is embedded in at least one side of said sheet.
Claim 7
Dependent Claim
40 words
A structure according to claim 1 in which said elastomeric adhesive comprises a composite layer of a sheet material and a layer of adhesive on each side thereof for adherence to said sheet liquid impermeable material and to said sub-surface.
Claim 8
Dependent Claim
38 words
A structure according to claim 1 in which said elastomeric adhesive is a layer of rubberized adhesive having a thickkness of about one-eighth inch and said sheet material has a thickness of from about 2 to 8 mils.
Claim 9
Dependent Claim
33 words
A structure according to claim 6 in which said adhesive for adhering the composite sheet material to the sheet liquid impermeable material is a layer of asphalt rubberized asphalt about 1/16 inch thickness.

A structure according to claim 3 in which said bonding agent is applied as a layer on said sheet material in a thickness of about 2 mils.
Claim 11
Independent Claim
99 words
A method for attaching a frangible thin facing veneer to a planar sub-surface comprising: causing adherence of a pre-manufactured liquid impermeable sheet to a sub-surface by an adhesive layer and applying said frangible veneer thereover while in a wet slurry state and bonding said frangible layer to said liquid impermeable sheet through a bonding agent compatible with said impermeable sheet and facing veneer whereby said frangible layer is rigidly secured to said liquid impermeable sheet, and wherein the adhesive is selected so that said adhesive layer will allow lateral movement of said sub-surface relative to said frangible thin veneer.
Claim 12
Independent Claim
99 words
A method for attaching a frangible thin facing veneer to a planar sub-surface comprising: causing adherence of a pre-manufactured liquid impermeable sheet to a sub-surface by an adhesive layer and applying said frangible veneer thereover while in a wet slurry state and bonding said frangible layer to said liquid impermeable sheet through a bonding agent compatible with said impermeable sheet and facing veneer whereby said frangible layer is rigidly secured to said liquid impermeable sheet, and wherein the adhesive is selected so that said adhesive layer will allow lateral movement of said sub-surface relative to said frangible thin veneer.
Claim 13
Dependent Claim

A method as claimed in Claim 10 wherein said liquid impermeable sheet is polyvinyl chloride and attaching a layer of porous material to the sheet of liquid impermeable material on the side thereof which is bonded to said frangible thin layer.
Claim 14
Dependent Claim
24 words
A method as claimed in Claim 11, attaching said layer of porous material to said sheet of liquid impermeable material by partial embedment therein.
Claim 15
Dependent Claim
48 words
A method as claimed in claim 12, attaching said layer of porous material to one side of said sheet of liquid impermeable material by heating said sheet of liquid impermeable material to a temperature wherein said material softens whereby said layer of porous material becomes partially embedded therein.
Claim 16
Dependent Claim
69 words
A method as claimed in claim 10, wherein said liquid impermeable sheet is provided, on one side to be bonded to said frangible thin veneer, with a pre-applied water activatable bonding agent compatible with said frangible veneer and wherein said method includes the step of wetting said bonding agent before application of the frangible layer thereto and wherein said frangible veneer is applied when said bonding agent is wet.
Claim 17
Dependent Claim
65 words
A method as claimed in claim 14 wherein said liquid impermeable sheet is provided, on one side to be bonded to said frangible veneer, with a pre-applied water activatable bonding agent for said frangible veneer and wherein said method includes the step of applying said frangible veneer as a wet slurry mix whereby moisture in the slurry mix provides water to activate the bonding agent.
Claim 18
Dependent Claim
58 words
A method as claimed in claim 10 wherein said liquid impermeable sheet is polyethylene or polyvinyl chloride, abrading one surface of said liquid impermeable sheet to roughen the surface texture thereof, applying a contact cement thereto, and heating said surface to the softening temperature of the sheet whereby said contact cement dries and forms a roughened surface texture.
Claim 19
Dependent Claim
39 words
A method as claimed in claim 16, adding a finely particulate solid selected from the group consisting of clay, limestone or silica dust to the contact cement prior to application of the contact cement to the liquid impermeable sheet.
