2. A wall system for a structure having an interior and an exterior, comprising:

a plurality of structural members forming a structural support for said wall system;

sheathing placed exterior of said plurality of structural members;

a moisture drainage product adapted to allow drainage of moisture from said wall system, comprising:

a sheet of corrugated material forming a plurality of ridges and grooves on opposite sides of said sheet of corrugated material, said sheet of corrugated material being relatively inflexible under a force applied generally perpendicular to said sheet, said sheet of corrugated material having a multiplicity of perforations; and

a sheet of material affixed to one side of said sheet of corrugated material, said sheet of material being water permeable;

wherein said sheet of material affixed to one side of said sheet of corrugated material extends beyond said sheet of corrugated material a distance, said sheet of material being wrapped under an edge of said ridges and grooves;

said product being flexible in a direction along said plurality of ridges and grooves allowing said product to be stocked in roll form;

said moisture drainage product being placed exterior of said sheathing with said ridges and grooves being oriented in a generally vertical direction with said sheet of water permeable material facing said exterior; and

an exterior veneer placed exterior of said moisture drainage product.

3. A wall system as in claim 2 wherein said sheet of material is wrapped under an edge of said ridges and grooves at a bottom of said wall system.

4. A product adapted to allow drainage of moisture from a wall of a structure, comprising:

a sheet of corrugated material forming a plurality of parallel ridges and grooves approximately 3/16 of an inches (0.48 centimeters) deep and approximately 7/16 of an inch (1.11 centimeters) on center on opposite sides of said sheet of corrugated material, said sheet of corrugated material being relatively inflexible under a force applied generally perpendicular to said sheet, said sheet of corrugated material having a multiplicity of perforations; and

a sheet of material affixed to one side of said sheet of corrugated material, said sheet of material being water permeable;

said product being flexible in a direction along said plurality of ridges and grooves allowing said product to be stocked in roll form;

wherein said sheet of material affixed to one side of said sheet of corrugated material extends beyond said sheet of corrugated material a distance allowing said sheet of material to be wrapped under an edge of said ridges and grooves.

5. A product as in claim 4 wherein said plurality of ridges and grooves are oriented vertically.

6. A product as in claim 4 wherein said plurality of ridges and grooves in said sheet of corrugated material are evenly spaced.

7. A wall system for a structure having an interior and an exterior, comprising:

a plurality of structural members forming a structural support for said wall system;

sheathing placed exterior of said plurality of structural members;

a moisture drainage product adapted to allow drainage of moisture from said wall system, comprising:

a sheet of corrugated material forming a plurality of ridges and grooves approximately 3/16 of an inches (0.48 centimeters) deep and approximately 7/16 of an inch (1.11 centimeters) on center on opposite sides of said sheet of corrugated material said sheet of corrugated material being relatively inflexible under a force applied generally perpendicular to said sheet, said sheet of corrugated material having a multiplicity of perforations; and

a sheet of material affixed to one side of said sheet of corrugated material, said sheet of material being water permeable;

said product being flexible in a direction along said plurality of ridges and grooves allowing said product to be stocked in roll form;

said moisture drainage product being placed exterior of said sheathing with said ridges and grooves being oriented in a generally vertical direction with said sheet of water permeable material facing said exterior; and

an exterior veneer placed exterior of said moisture drainage product;

wherein said sheet of material affixed to one side of said sheet of corrugated material extends beyond said sheet of corrugated material a distance, said sheet of material being wrapped under an edge of said ridges and grooves.

8. A wall system as in claim 7 wherein said sheet of material is wrapped under an edge of said ridges and grooves at a bottom of said wall system.
