Chris’s Mother’s home had some water and moisture issues in her crawl space and wanted help to encapsulate it.
Basement & Radon Solutions, BRS Pros a few things at the home, and this is how it went…1. We removed all contaminated sub-floor insulation from the crawl space.2. The crawl space sub-floor wood components were cleaned and deodorized for wood decaying fungi and organic growth.3. After cleaning an EPA registered fungicide was completely fogged throughout the crawl space. It 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.4. We sprayed the rim joists and sill plates with our class A fire rated polyurethane closed cell spray foam insulation. 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.5. We installed out Sump Pump Pro-Series package. The Sump Pump basin with a removable (flush with floor) lid is covered with stone in low point in left front corner of the crawl space (as looking at the front door). The system includes a 1/3 HP cast iron primary pump with a dual float cage that protects debris from the float. Included is a deluxe controller that monitors pump and power conditions and will sound an alarm if problems are detected or a high water warning in the sump. Additionally, it activates pump weekly to exercise and extend the pumps life.6. The foundation vents were completely sealed with 2 poly-foam insulation from the interior of the crawl space, preventing exterior air and moisture entering crawl space.7. Installed our 9 mil white 100% woven reinforced ground liner on the foundation wall. The wall liner was mechanically fastened/sealed to the foundation walls.8. Next we installed our fiberglass blanket insulation with white vapor barrier to interior perimeter foundation walls. Insulation is approximately 3 1/2″ thick which offers an R-11 insulation factor (code compliant for new construction). Insulation was mechanically fastened approximately 6″ from the top of the interior masonry foundation wall to allow a termite inspection. The insulation covers wall to approximately 6″ off the ground and taped at the bottom.9. Then, we installed our 15 mil Premium (walk on, store on) white 100% woven reinforced radon ready crawl space system. The premium ground liner was nailed/sealed approximately 6″ to 12″ above the ground 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 crawl space 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 our liner.10. We installed a 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 the 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. This 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 does carry a five year transferable warranty to prevent water on top of the ground liner.11. We also installed an Aprilaire 1820. This model will remove up to 70 pints of moisture per day! It comes with a 5 year manufactures warranty. 12. Lastly, we installed a Hygrometer. Remote Temperature and Relative Humidity Meter stand alone unit with one remote sensor. The wireless remote sensor was mounted in the crawl space to give them an accurate reading of relative humidity. This product will help monitor the effective humidity of the dehumidifier in the crawl space.It was a pleasure helping Chris and his Mother make her home happy, healthy, and safe!”
