The embodiments provide a water proof structure, which protects the structure from water damage, such as in the event of a natural disaster.
The invention creates a dry zone to prevent moisture from wicking through the concrete.
The invention protects the environment from the presence mold spores, which prevents individuals from having adverse health effects.
The invention adds structural strength to the bricks and the frame to protect from future damage.
The invention is for a remediated water-damaged masonry building having a foundation supporting a remediated outer wall and a remediated inner wall wherein zero masonry has been removed from the remediated water-damaged masonry building.
The method involves visually determining a dry height of a water damaged interior portions of an installed masonry exterior wall, the installed masonry exterior wall comprising studs and wallboard.
The method involves installing at least one beam on the water damaged interior portions of the installed masonry exterior wall to transfer load from the water damaged interior portions of the installed masonry exterior wall to the beam.
Next, construction materials are cut out of the water damaged interior portions of the installed masonry exterior wall from 1 foot above the dry height to the foundation.
The method involves clearing a masonry ledge and plurality of weep holes of the water damaged interior portions of the installed masonry exterior wall and an inner surface of the water damaged outer wall removing unwanted construction materials.
The next step of the method involves chemically etching simultaneously the masonry ledge and the foundation to a predetermined width and to the dry height forming an etched inner surface and etched foundation.
The method involves installing pest control wire over at least one weep hole.
A reliner is applied to the etched inner surface and over the pest control wire.
Next, a parging coat of reliner is applied to the reliner, then a curing agent is applied on the parging coat.
The method includes trapping moisture in the curing agent by using a cover that is configured to prevent oxidation of the reliner and allow proper cure of the reliner preventing cracking forming a cured reliner.
An isolation membrane is then painted on the curing agent and on the foundation.
A sill plate, a wag panel, house wrap, and studs are then used to rebuild water damaged interior portions of the installed masonry exterior wall, creating a dry area between wag panels and the isolation membrane. Each wag panel extends 0.5 inches to 1 inch below the sill plate eliminating growth of mold, fungus, and dampness in the interior portions of the installed masonry exterior wall.
The method includes caulking the sill plate with a silicon sealant that effectively connects the sill plate to the foundation.
Wag panels are then connected to the studs and the sill plate.
The beam is then removed.
Closed cell foam is installed over the wag panels forming a continuous seamless remediated inner wall that prevents at least 95% water incursion into the masonry building after remediation even though zero masonry has been removed from the masonry building.
Finally, sheet rock is installed over the closed cell foam.
