Virginia contacted us here at BRS Pros to help encapsulate her crawl space. She was having some water intrusion and also had moisture on the block foundation.
Basement & Radon Solutions, BRS Pros, did quite a bit of work for Virginia and it went like… 1. Removed all contaminated insulation from crawl space. 2. Sprayed foam on the rim joists and sill plates. This foam is a 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. This closed cell foam insulation (moisture and air will not penetrate this product) fills and seals the cracks, cavities, and joints. This product also reduces cold spots in the floor adjacent to the main level walls. 3. Installed the fiberglass blanket insulation to the sub-floor of the crawl space. 4. We installed a hydra-channel dewatering system in the crawl space. A clean trench was dug along the full interior perimeter of the crawlspace foundation. 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. The hydra-channel system does carry a five year transferable warranty to prevent water on top of the ground liner. 5. We installed some corrugated piping in the crawl space. This is for in the event of Virginia ever needing to add a radon system later down the road. 6. We then installed a 9 mil liner to the walls of the crawl space. This liner is a white 100% woven reinforced liner on the foundation wall. The wall liner was mechanically fastened/sealed to the foundation walls. 7. We also installed a 15 mil liner to the ground of the crawl space. This liner is our premium (walk on, store on) 15-mil white 100% woven reinforced radon ready crawl space system liner. The 15-mil woven ground liner will control moisture vapor and dampness from the ground. This product will not off gas (known on Google as crawlspace cat urine odor”), we guarantee it!! Our woven ground and wall liners are antibacterial, meaning mold and other organic growth will not grow to our liner. 8. We installed an Aprilaire 1820. This model removes up to 70 pints of moisture a day! It also comes with a 5 year manufactures warranty. Proudly made in the USA. 9. Lastly, we installed a hygrometer to the crawl space. This is a remote temperature and relative humidity meter stand alone unit with one remote sensor. The wireless remote sensor was mounted in Virginia’s crawl space to give her an accurate reading of relative humidity in the crawl space. This product helps monitor the effective humidity of the dehumidifier in the crawl space. It was a pleasure to help Virginia make her home safe, healthy, and happy! Virginia also left us a 5 Star Google Review. Check it out here: https://goo.gl/maps/ePJDp3rrRjy1RF8j9“
