BRS Pros helped Joy wit her crawl space and here are some steps we took…
Mold Remediation – Phase 1 of this work consisted of cleaning the crawl space sub-floor of wood decaying fungi and organic growth. After cleaning, Phase 2 consisted of fogging the crawl space. Phase 2 will kill 99.9% of mold spores and will inhibit the growth of mold and mildew.
Spray Foam – Class A fire rated polyurethane closed cell spray foam insulation was sprayed on the rim joists and sill plates. It prevents air infiltration (unlike fiberglass insulation) and will insulate the wood band plates (rim joists) above the masonry foundation wall. Closed cell foam insulation (moisture and air will not penetrate this product) will fill and seal cracks, cavities and joints. Fiberglass insulation will not perform to prevent air infiltration. This product application will reduce cold spots in the floor adjacent to the main level walls.
Dewatering System – A clean trench for the Hydra-Channel was dug adjacent to the foundation footing along the four interior perimeter foundation walls, to manufacture’s instructions adjacent to the footing. The Hydra-Channel engineered fusion welded high strength polyethylene water system will remove storm water up to 70% faster than a pipe and stone system. It will allow water to flow freely to the in-ground sealed sump pump/basin located in the right rear interior of the crawl space. The Hydra-Channel system carries a five year transferable warranty to prevent water on top of the ground liner.
Sump Pump – Installed our “Single Pump System” with a removable (flush with floor) lid covered with stone in left front corner of crawl space (as looking at the front door). The system includes 1/3 HP cast iron primary pump with dual float cage that protects debris from float. Included is deluxe controller that monitors the pump and power conditions and will sound an alarm if problems are detected or a high water warning in the sump. Additionally, it activates the pump weekly to exercise and extend the pumps life.
Foundation Vents – Foundation vents were completely sealed with poly-foam insulation from the interior of the crawl space preventing exterior air and moisture from getting into the crawl space.
Wall Liner – Installed our 9-mil white 100% woven reinforced wall liner. Wall liner was mechanically fastened with nails designed for foundation walls to within 6″ of the top of the crawl space foundation wall to provide a complete future termite inspection. Mechanically fastening wall liner is a permanent solution opposed to just caulk or tape which will result in future maintenance or failure of the system.
Blanket Insulation – Installed our fiberglass blanket insulation with white vapor barrier to the interior perimeter foundation walls. Insulation is 4″ thick which offers an R-13 insulation factor (code compliant for new construction). Insulation was hung approximately 6″ from the top of the interior masonry foundation wall to provide a termite inspection and will cover the wall to approximately 4″ off the ground.
Radon Ready & Ground Liner – Installed our Premium (walk on, store on) 15-mil white 100% woven reinforced radon ready crawl space system. The liner was mechanically fastened with nails designed for foundation walls to provide a permanent fastening system. (Caulking or taping liner to foundation walls is a temporary system and will become a maintenance issue.) The premium ground liner was nailed/sealed approximately 6″ to 12″ above the earth in the crawl space to the foundation wall. A radon piping system was installed below the ground liner, the piping system will be used in the future when the home is tested for radon gas and requires a complete radon system. 15-mil woven ground liner will control moisture vapor and dampness from the ground. Most crawlspace liners are partially reinforced, our woven liner is 100% reinforced and tough unlike competitive brand liners that are only 10% reinforced. This product will not off gas (known on Google as “crawlspace cat urine odor”, go ahead and check it out), we guarantee it!! Our woven ground and wall liners are antibacterial, meaning mold and other organic growth will not grow to the liner.
It was a pleasure helping Joy make her home happy, healthy, and safe!
