Hello all,I have spent the last 2.5 years renovating my home from 1910 and the last part of the project is the basement. Good news is I have NO water penetration issues at all AND the basement has poured concrete with 4 floor drains. Bad news, the floor is uneven.The problem is the poured concrete floor is sloped towards each of the 4 floor drains. Fantastic that someone did this but makes it impossible to have a flat floor to do a finished basement with a fake wood or tile floor. I am searching for ideas on how anyone would level this floor, it's about 800 square feet and the highest point and lowest point (where the drains are) is a gentle slope difference of 2.5-3 inches. I am not worried about water ingress down here as I have owned the house a long time, it is on a hill and I have a french drain system around the outside.Potential solutions:I have thought about having additional concrete poured to smooth out the dips towards the drains, I have also through about doing a floating 2X4 pressure treated floating subfloor essentially making pseudo beams that rest on the concrete and then placing a MDF floor on it and then my flooring of choice on top. I would lose 3-4 inches of height if I did it this way, thankfully the basement is fairly tall.Any other ideas?Here are some photos of the basement.https://ift.tt/34KxPvL via /r/DIY https://ift.tt/2LC6hRL
