Hello, I recently had a company come out and "waterproof" or water mitigate...my basement, they sprayed for mold, trenched down for a french drain, drilled weep holes around the perimiter and installed new sump pump, they also installed a ventilation system called EZ Breathe which moves bad air out. They lined the walls with some sort of plastic membrane (Vapor Barrier) and a dimpled sheet at the bottom as seen in this photo: [IMG]https://ibin.co/49upcQxeF3jy.png[/IMG] My question is, can i put up rigged foam board against this membrane/plastic prior to framing...can i frame directly over top the membrane? I believe the membrane is a vapor barrier called Vaporbright which is a multi-ply nylon weave and polymer laminate. I was planning on going out and buying an R-10 rated foam board to fill the Rim Joists and then place on top of the rest of the membrane. After searching for similar issues on these forums i believe what im looking to do is essentially what is being described as "Option 1" here: [url]https://www.doityourself.com/forum/basements-attics-crawl-spaces/583429-insulate-frame-foundation-walls-membrane-basement.html[/url]

Hello We have an older home (1924) with an old concrete and stone type foundation. Full basement Home is only 1200 ft/sq The basement has always been humid and damp particularly when there have been prolonged heavy periods of rain and the ground becomes saturated. At this point moisture seeps and drips through certain parts of the old foundation wall, and random spots of moisture appear in the middle of the concrete floor. I do keep the windows open for ventilation, and run a fan only when we are home. I have lived here for 40 years and while I am used to this behavior this summer in the Northeast has been unbearably humid and damp. For the first time ever I have noted mold and mildew all over the beams and floor joists!! My first question is what is the best humidifier I can buy ASAP and will one be enough for a 1200 ft/sq basement My next question is what is the best way to get rid of this mold? And finally do you all think sealing the outside of the foundation and putting in footing drains will be the best solution for the moisture problem (should I be asking this question in another spot on the forum?) Any help will be much appreciated Thanks
