Wire mesh sandwich construction and method for making the same

A method for making a wire mesh sandwich construction which comprises:

• providing an array of line wires;
• overlaying a barrier material having perforations therein onto said array of line wires;
• placing an array of cross wires onto said barrier material, said array of cross wires spaced apart from said array of line wires to form a mesh construction, said mesh having points of intersection between said array of line wires and said array of cross wires, said points of intersection being in registration with said perforations;
• securing said array of line wires to said array of cross wires through said perforations at said points of intersection to said array of cross wires to form the wire mesh sandwich construction.

A wire mesh sandwich construction which comprises:

• an array of line wires;
• an array of cross wires overlying said array of line wires;
• and
• a barrier material disposed between said array of line wires and said array of cross wires, said array of line wires being spaced apart from said array of cross wires to form a grid pattern and points of intersection therebetween, said array of line wires being joined to said array of cross wires at said points of intersection and through said barrier material, thus securing the barrier material between said array of line wires and said array of cross wires.

A composite barrier comprising:

• parallel line wires defining one face of said barrier;
• parallel cross wires defining an opposite face of said barrier, said cross wires extending transversally across said line wires at intersections;
• and
• a barrier material interposed between said line wires and said cross wires, said line wires being joined to said cross wires through openings in said barrier material at said intersections.
