Clean water springs under my concrete basement floor. Concrete gets discolored(like wet ) and damp when it rains. Floor has several small cracks that are from hair-line to 1/4 inch wide. The floor is fairly level with the exception of small "eruptions" at the cracks. Would like to finish basement as a living space. Would sump pump(s) help?? I thought about removing the entire floor and pouring new concrete...Is there an easier solution??
