Abstract: A vapor mitigation apparatus and method for use with the construction of a building. The apparatus includes a vertical member configured to be affixed to a foundation wall proximate a footing that is supporting the foundation wall. The vertical member has a first end located proximate to a footing and a second end. A horizontal foot is located at the first end of the securing piece. The horizontal foot is configured to rest against the footing. The apparatus may include a mechanical clip located at the second end of the vertical member and is configured to secure a gas impermeable membrane. In the alternative, the vertical member and the gas impermeable membrane are of a unitary structure. The method includes securing the apparatus to the foundation wall, sealing the gas impermeable membrane to a membrane that is covering the footings or granular base of the building and then creating a concrete slab by pouring concrete over the footing and apparatus.
