Abstract
The present invention provides a device and method to maintain the integrity of a vapor barrier for use with concrete slab on grade construction. In accordance with the present invention an apparatus to repair a punctured concrete slab vapor barrier includes a substantially planar concrete slab vapor barrier patch having a resealable aperture to receive a removable, substantially upright support. The patch is secured to the existing vapor barrier and the concrete is poured and substantially set. The support is removed and the malleable concrete flows, causing the engagement of the resealable aperture, thereby repairing the punctured vapor barrier.
