Drip line water in basement
Comments (11)It isn't necessarily the case that the landscape company that did the planting created the grade issue. One would need to know the history and the particulars of the contract. A company tasked simply with planting may not have the obligation to correct a grade issue that should have been fixed by the original builder. It might be the case that the condition existed and was simply not pointed out by the homeowner or the landscape planting company. It would have been nice and more professional/thorough if they had pointed it out and said, "For a little extra, we can take care of that." We just don't know what happened. Nevertheless, it's probably an easy fix, depending on the severity of the problem. If the OP could quantify the problem and explain/show how grade interfaces with the foundation wall, maybe we could suggest what to do....See Moremoisture/water in basement
Comments (13)Thanks SJ and Springtime Builders. We did not have a basement waterproofing expert on hand. Definitely should have done this before starting to finish the basement! The house had been gutted, including the basement. We had basically exposed concrete floors and walls (foundation). No visible cracks. The walls (old and new) were insulated before the drywall was placed. Our contractor thinks this is a condensation issue. While he does think there are drainage issues under this very old house, he thinks addressing this would involve tearing out the concrete floor and digging several feet further to install a drainage system and would be extremely expensive. He does not think we have a crack/leak in the slab or foundation. He has advised that we install this: https://www.wavehomesolutions.com/wave-moisture-control-basement-unit/ Of note, as the house is nowhere near being completed, none of our HVAC components are up and running yet, so there's no air circulating in the house at all. Perhaps once the house is powered up (and with the addition of this ventilating/circulating unit), the moisture issue will improve? Is there a reliable way to test if we are dealing with condensation vs seepage from a porous slab? We are not currently living in the house and are not on-site regularly. I will try to take some photos, especially if there are active moisture issues when I am there. Thanks again to all!...See MoreOdd Situation - Water in Basement
Comments (2)It sounds like it could be underground stream or like you said high water table. Usually most engineers or excavation guys will suggest to keep the basement floor at least 12" above the water table. I would consult with an engineer and do a few soil tests before you start spending money. Most likely they will suggest an interior french drain... cut the basement floor along perimeter, allow the water to by-pass the foundation and install pipe and stone under the slab tied into a sump pump. I'm surprised they didn't do that from the get go when they knew there was a water issue. Good luck...See MoreHuge Water Issues/Basement Smells
Comments (20)I don't think it's impossible to waterproof a stone foundation. I haven't researched it, and maybe someone else here has experience. My guess is that you'd probably have to parge the stone from the outside with cement or something similar, then add the usual sealer and membrane over that. I suppose you'd have to excavate inside the crawl space to get to that part of the foundation, which doesn't sound like any fun at all. If you just can't do a proper exterior waterproofing, I'd suggest doing all the other (exterior) steps on the list - gutters, downspouts, grading, swales. That will at least reduce the amount of water entering the cellar. If it's still too damp, then you need to remedy that. To consider crawl spaces, ventilating them used to be the standard practice. Today there is a trend toward sealing and conditioning them. Personally, I raise an eyebrow at the idea of heating and air conditioning a space that nobody but mice is living in, but who am I to say? In your case, that's all moot. If your cellar is going to be damp, you have to get rid of the excess humidity somehow. You can run up a big power bill with multiple dehumidifiers. Others may disagree, but IMO, it's more economical to ventilate the cellar. You can replace your cellar windows with crawl space vents, and make one or two of them exhaust fans. Fans cost around $100-150 each, and use considerably less electricity than dehumidifiers. I'll be interested to see what others suggest....See Morewhaas_5a
