Trying to level a 70 year old basement.
I am going to finish off my basement but the floors are unlevel in some areas by up to 4 inches. What would be the most cost effective and long lasting way to fix this? Any help would be greatly appreciated.
I'm not sure if your low areas are over a long span on small, but I have never been satisfied with any basement leveling job unless it was a complete pour. I have seen patch jobs that do not last and heave if the basement takes in water. You can look into leveling products, but they are difficult to use and you would need to make level lines in order to have a guide.
