CLAIMS

1 . A conductive mesh for a leak detection system formed from single conductive layer.

2. The conductive mesh of clam 1 , wherein the conductive mesh comprises a plurality of first members and a plurality of second members, wherein the first and second members form a grid.

3. The conductive mesh of clam 2, wherein the grid is formed by crossing first and second members being held together.

4. The conductive mesh of clam 3, wherein the crossing first and second members are held together by a welded joint.

5. The conductive mesh of any preceding claim comprising plastics material and carbon mixed in with the plastics material.

6. A leak detection system comprising at least one geomembrane, at least one conducting mesh, an electrical source and at least two electrodes.

7. A geomembrane incorporating a conductive mesh.

8. A method of forming a conductive mesh, the method comprising:

extruding a plurality of first and second members;

arranging the first and second members in a grid, and

connecting the plurality of first and second members using a plurality of fastening means.

9. The method of claim 8 further comprising mixing carbon into a molten plastics material to be extruded.

10. The method of claim 9 wherein the extruding comprises extruding the plurality of first and second members from the molten plastics material comprising carbon.

1 1 . The method of any one of claim 8 to 10, in which the quantity of carbon is varied depending upon the particular use intended for the conductive mesh.

12. The method of any one of claim 8 to 10, in which the fastening means comprise a plastic extrusion weld, a plastic fusion weld, a zip tie or other mechanical fastener.

13. A method of installing a plurality of sheets of geomembrane, wherein each geomembrane comprises a pre-attached conductive mesh, the method comprising:

laying a first sheet of geomembrane;

laying a second sheet of geomembrane;

connecting the first and second sheets of geomembrane, and

connecting a first and second pre-attached conductive meshes.

14. The method of claim 13, in which the connecting of the first and second sheets of geomembrane employs a plastic extrusion welder.

15. The method of claim 13, in which the connecting the first and second sheets of geomembrane employs a plastic twin or single track fusion welder or hot wedge welder.

16. The method of claim 13 or claim 14, in which the connecting the first and second pre-attached conductive meshes employs a plastic extrusion welder, a plastic hot air welder or compression between two heated plates to create a fusion weld, or a zip tie or other mechanical fastener.
