Basement & Radon Solutions, BRS Pros, did some work to fix the issues and here is how it went…1. A 4 suction pipe was installed into the ground of the crawl space. For in the event the home is tested for radon in the future and found it to be elevated, this component will be used with the additional exterior radon system to correct radon levels.2. Installed a partial perimeter interior French Drain with a lateral drain. We installed the perimeter drain starting at the first footer step up before concrete pad on left foundation wall. Then continuing alongside concrete pad towards the rear and along the entire rear foundation wall. The lateral French Drain line runs from the low point at bottom of the slope through middle of crawl space. Then sloping towards the rear and connecting directly to sum pump basin. The French drain consists of 4″ plastic water channel and 3/4″ washed stone wrapped in filter fabric. The French drain system was then connected to our sealed sump pump/basin in the crawl space and then it was extend and discharged into the left front corner. The drain was connected to the ice cop, 3 inch drain and a bubbler pot.3. Installed our Thermalshield liner which is a metal faced reflective wall liner with a plastic moisture barrier. ThermalShield is 90 mil thick, Class A Fire Rated with a near zero perm rate. It reflects the natural occurring heat generated in the crawl space away from the foundation walls to provide a much warmer space.4. Installed our premium 15 mil vapor barriers to the ground of the crawl space. It is a walk on, store on approved 15-mil white 100% woven reinforced liner. This ground liner will control moisture vapor and dampness from the ground. Our woven ground and wall liners are antibacterial, meaning mold and other organic growth will not grow to our liner.5. Next, we installed an Aprilaire 1850 dehumidifier in the crawl space. This dehumidifier will remove up to 95 pints of moisture per day! It’s proudly made in the USA and comes with a 5 year manufactures warranty. 6. Lastly, we installed the Hygrometer. It is a 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 David an accurate reading of relative humidity. This product will help him monitor the effective humidity of the dehumidifier in the crawl space.It was a pleasure helping David get his home happy, safe, and healthy!”
