I am refinishing basement. In one side of the basement there is a 2" hole drilled in the wall near the floor. From the hole along the wall there is shallow channel in concrete floor going to the sump pump pit. I talked to a waterproofing contractor and he said that the hole had been drilled to released water pressure from outside the foundation and let water come inside the house and run through the channel to the sump pump. For year the I have been living in the house I saw only once water coming through the hole. Now my question. Unfortunately, the channel is very shallow, uneven and too wide, it's done ugly. I don't know how to box it or fix stud to the floor over it when framing the wall. What should I do to make it better and be able to frame the wall? I thought of making with electric hummer a groove in concrete floor along the wall where the channel currently is and burying a plastic hose running from the hole to the sump pump pit. The hose would run parallel to the wall 1" from the wall. The hose would be under the floor surface so I can easily put a frame stud over it. Is my idea suitable or not? I have basically two concerns. The first is can I damage the structure or foundation if I start using heavy hummer to break concrete floor for the channel close (1") to the wall? The second is how to clean the berried plastic hose of something (dirt or stones) will block it? Also what diameter should I use for the hose? Do I need to maintain a slope in the hose from the hole to the sump pump pit?

Hello all, I would like to put up a basement wall (I have never attempted this before). I have an unfinished basement wall. Cinder block painted white, with a drop ceiling (about 25 years old). Could you please tell me how I would go about doing this. I was told to build the frame on the floor with 2 x 4's and then raise it. Would it make a difference if I used 2 x 3's? Would it be possible to build it in sections. Top part then bottom part then put the studs in. Any help would be appreciated. Also, I think I have all of the tools 1) saw 2) nails 3) hammer 4) screwdrivers Thanks, Gary
