Basement Waterproofing & Insulating
water is almost an unstoppable force. first off you need major regrading done outside. if water can't find a place to get in? it will make one! what is the purpose of the plastic on inside the block wall? the water gets into the plastic and runs down. it sounds like the sump bump is at best, at the high point of the floor? you could rent a jack hammer and cut a trench directing the water to the sump pump, that might help some. you could do like we did back in the 50's&60's.... dig all around the house, down to the footers. acid wash the clock, roll on tar into the block thickly, then roll plastic over the tar, but you'd practically need to sift the dirt and shovel it in by hand, any rocks or harp objects poke holes in the plastic negating the who process. fill around the footers with stone and install a french drain and pipe the water far away from the house, eve n then, the water will likely go under the footers and come up through the floor at some point, like where the floor meets the wall? or even out in the middle of the floor, like I said, "water will find a way in or make one"
whatever you decide to do? I wish you luck! the mold has got to go!!
