Description
REFERENCE TO PENDING APPLICATIONS
[0001] This application does not claim the benefit of any issued
U.S. patent or pending application.
TECHNICAL FIELD
[0002] The present invention is generally directed toward a vapor
mitigation, and more specifically, toward the mitigation of radon
vapor in the construction of buildings.
BACKGROUND
[0003] Radon is a colorless, odorless gas that can cause lung
cancer. Radon gas can move through small spaces in the soil and
rock upon which a house is built. It can seep into a home through
dirt floors, cracks in concrete walls and floors, sumps, joints,
basement drains, under the furnace base, and jack posts if the base
is buried in the floor.
[0004] FIG. 1 illustrates a prior art system 10 to reduce the
amount of radon gas from seeping into a house. As illustrated, the
prior art system 10 utilizes a gas permeable layer 12 that is
created below the building slab 14, which is usually made from
concrete. The gas permeable layer 12 allows the radon gas to move
laterally beneath the slab 14 to the location where a vent pipe can
collect the gas and transport it away from the building. The gas
permeable layer 12 is usually created with drainage rock, crushed
gravel and/or other drainage material. Surrounding the gas
permeable layer 12 are the building's footings 16 and foundation
wall 18. The prior art system 10 places a layer of plastic sheeting
20 between the gas permeable layer 12 and the slab 14. The joint
seams and all openings between the foundation wall 18 and slab 14
are sealed with an elastomeric sealant 22 such as polyurethane
caulk.
[0005] The prior art, however, has disadvantages. The footings are
purposely poured very rough and porous for proper adhesion of the
foundation wall, which is poured on top of the footings. The
footings can become soiled with dirt, sand, fine gravel, or other
contaminants preventing a proper seal between the footing and
membrane.
[0006] Further, it is difficult to determine if the plastic
sheeting 20 remained in place over the gas permeable layer 12 after
the concrete that forms slab 14 is poured thereon, or if the
plastic sheeting 20 has moved. If the plastic sheeting 20 remained
in place, an airtight seal may be created. However, if there is
movement, an airtight seal may not have been created. Due to the
sheeting 20 being located under the slab 14, there is no way to
make this determination.
[0007] Accordingly, there is a need for an apparatus and method to
address the issues set out above.
SUMMARY
[0008] The present invention is generally directed toward a vapor
mitigation, and more specifically, toward the mitigation of radon
vapor in the construction of buildings.
[0009] In one aspect, a vapor mitigation apparatus for use with the
construction of a building is disclosed. The building has a gas
permeable layer surround by a foundation wall and footing. A sheet
of plastic sheeting is placed between the gas permeable layer and
the buildings slab. The term plastic sheeting is used to mean any
type of plastic sheet, membrane, film or other continuous polymeric
material that is used to separate areas or volume to act as a
barrier.
[0010] The apparatus includes a vertical securing piece configured
to be affixed to the foundation wall by adhesion or other known
securing fasteners. The securing piece has a first end located
proximate to the footing and a second end. A horizontal foot is
located at the first end of the securing piece and extends away
from the securing piece. The horizontal foot is configured to rest
on the footing that is supporting the foundation wall. A mechanical
clip is located at the second end of the securing piece and is
configured to secure the piece of plastic sheeting. This creates an
airtight seal between the ground below the building and the
building.
[0011] In some aspects, the mechanical clip includes a first jaw
member and a second jaw member that is hinged to the first jaw
member. In the locked, or closed, position, the first jaw member
and second jaw member are configured to secure the piece of plastic
sheeting therebetween.
[0012] In some aspects, the mechanical clip includes a base member
extending substantially horizontally away from securing piece. The
base member has a locking portion at its distal end. The mechanical
clip further includes a retention member that configured to be
depressed against the locking portion. In the locked, or closed,
position the retention member and locking portion are configured to
secure the piece of plastic sheeting therebetween.
[0013] In one aspect, a method for vapor mitigation in the
construction of a building is disclosed. The method includes
utilizing a vapor mitigation apparatus having a vertical securing
piece having a first end located and a second end, a horizontal
foot located at the first end of the securing piece and extending
away from the securing piece, and a mechanical clip located at the
second end and configured to secure a piece of plastic sheeting.
The method includes affixing the vertical securing piece to the
circumference of the foundation wall such that the horizontal foot
rest on the footing, placing a piece of plastic sheeting over the
gas permeable layer, securing the ends of piece of plastic sheeting
to mechanical clip thereby creating a vapor barrier over the gas
permeable layer, and creating a slab of concrete by pouring a
sufficient amount of concrete over the vapor mitigation apparatus
and plastic sheeting.
[0014] Other aspects and features of the present invention will
become apparent to those ordinarily skilled in the art upon review
of the following description of specific embodiments of the
invention in conjunction with the accompanying figures.

DETAILED DESCRIPTION OF THE INVENTION
[0035] FIG. 2 illustrates an embodiment of a schematic
representation of an apparatus 70 of the present invention in use
to reduce the amount of radon gas from seeping into a house. As
illustrated, house includes a gas permeable layer 52 that is
created below the building slab 60. Surrounding the gas permeable
layer 52 are the building's footing 54 and foundation wall 56. A
layer of plastic sheeting 58 is placed between the gas permeable
layer 52 and the slab 60. The apparatus 70 is affixed to the
foundation wall 56 by an adhesive 72 and rests against the footing
54. Further, the plastic sheeting 58 is secured to apparatus 70.
When slab 60 is created by pouring cement over the footing 54, gas
permeable layer 52, plastic sheeting 58 and foundation wall 56, the
cement also encapsulates apparatus 70 therein. Thus, plastic
sheeting 58 is maintained in place to create an airtight seal from
radon leakage from the soil beneath the building. FIG. 2
illustrates some space between slab 60 and the footing 54, gas
permeable layer 52, plastic sheeting 58, foundation wall 56, and
apparatus 70. This is illustrative. When slab 60 is created, slab
60 will be directly against the footing 54, gas permeable layer 52,
plastic sheeting 58, foundation wall 56 and apparatus 70. No space
therebetween will remain.
[0036] As illustrated in FIGS. 3 and 4, an embodiment 100 of the
apparatus 110 of the present invention is disclosed in use.
Embodiment 100 includes a footing 102 supporting a foundation wall
104. A piece of plastic sheeting 106 is placed against footing 102,

mechanical clip 112, the plastic sheeting does not move or
otherwise pull away from the foundation wall 104 thereby creating
an airtight seal between the ground and base of the house.
[0039] To assist with the creation of the slab, the length of
securing piece 114 may be dimensioned as a gauge for the needed
depth of the concrete. For example, if the concrete slab needs to
be four (4) inches deep, the length of securing piece 114 may be
four (4) inches.
