Patent ID: 7654053

Claim:
An apparatus to repair a puncture in a concrete slab vapor barrier that is below a poured concrete slab, the apparatus comprising: a substantially planar concrete slab vapor barrier patch having a resealable aperture on a bottom side of the vapor barrier patch, the bottom side positioned to contact the concrete slab vapor barrier and the resealable aperture to surround a removable support that has punctured the concrete slab vapor barrier; and a collapsible chamber positioned on a top side of the vapor barrier patch, the collapsible chamber having a resealable aperture to receive the removable support and flexible sidewalls, the flexible sidewalls of which are of sufficient rigidity to substantially maintain the shape of the chamber upon receipt of the removable support and the flexible sidewalls lacking sufficient rigidity to support the weight of the poured concrete slab, such that the collapsible chamber collapses under the weight of the poured concrete slab and upon removal of the removable support from the concrete slab vapor barrier and the poured concrete slab, the resealable aperture on the bottom side of the vapor barrier patch and the resealable aperture of the collapsible chamber close, thus repairing the puncture in the concrete slab vapor barrier.
