A process of providing a dual waterproofing and methane barrier sheet system for a building, comprising the steps of:

• (a) taking at least one non-metallic layer and securing it to at least one layer of aluminum sheet to form a dual waterproofing and methane harrier sheet having an exposed non-metallic face, and an exposed aluminum face, and wherein securing at least one release layer onto at least a portion of said exposed non-metallic face;
• (b) securing said at least one release layer to an unfinished porous structure;
• and
• (c) applying one of concrete and shot-crete against said exposed aluminum face.

A process of providing a dual waterproofing and methane barrier sheet system for a building, comprising the steps of:

• (a) forming a wall, using one of concrete and shot-crete, and wherein said wall has an interior surface, and an exterior surface;
• (b) applying at least one primer to at least a portion of said exterior surface of said wall;
• and
• (c) taking at least one non-metallic layer and securing it to at least one layer of aluminum sheet to form a dual waterproofing and methane harrier sheet having an exposed non-metallic face, and an exposed aluminum face, and securing at least a portion of said exposed non-metallic face to at least a portion of an exposed face of said at least one primer.
