BRS Pros helped Dawn and here are a few steps we have taken…
Mold Remediation – Phase I of this work consists of cleaning the crawl space sub-floor of wood decaying fungi and organic growth. After cleaning, Phase 2 consists of fogging the crawl space. Phase II will kill 99.9% of mold spores and will inhibit the growth of mold and mildew. Decay and organic growth will be treated and cleaned, however, it is likely that some staining will remain due to any pre-existing damage to the wood members.
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 plate (rim joist) 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.
Hydra Channel – A clean trench was dug adjacent to the foundation footing along the four interior perimeter foundation walls. The Hydra-Channel was installed according 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 crawlspace. The Hydra-Channel system will carry a five year transferable warranty to prevent water on top of the ground liner.
Dual Sump Pump – Installed our Pro-Series PS-C33 Combination AC Primary Pump, AC/DC backup pump, 12 volt maintenance free battery and battery box in left front corner of the crawlspace (as looking at the front door). • Automatically switches to battery power when AC fails • Unique monitoring controller detects irregularities, sounds an alarm, and pinpoints problems and solutions on control panel • Primary pump with energy efficient PSC motor is continuous duty rated and water cooled • Primary pump controller allows for adjustable pump run time and exercises pump weekly to extend pump life • Dual float switches provide dependable activation for both primary and backup pumps • Backup will assist primary pump if excessive amounts of water are entering the sump • Maintains and recharges battery automatically • Alarm can be silenced during a power outage • Designed for use with wet cell or AGM / maintenance free batteries • USB Data Port and Remote Terminals connect to external devices such as a PHCC Pro Series CONNECT Module, home automation systems or other devices for remote notification.
Foundation Vents – Foundation vents were completely sealed with poly-foam insulation from the interior of the crawl space preventing exterior air and moisture into the crawl space.
Exterior Vents – Plastic exterior recessed vent covers were secured and sealed to the exterior masonry wall over the two existing foundation vents on front of home to seal the vent openings and improve exterior aesthetics on home. Color in black, and the cover will not rust.
Blanket & Wall Liner – Installed fiberglass blanket insulation with white vapor barrier to 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 wall to approximately 4″ off the ground. A reinforced 9-mil wall vapor barrier was mechanically fastened to foundation wall prior to fiberglass insulation to prevent any moisture/condensation from wall to contact insulation.
Ground Liner & Radon Ready – 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 also nailed/sealed approximately 6″ to 12″ above the earth in the crawl space to the foundation wall. A radon piping system was then 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.
