I am wanting to finish my basement. I fixed all of the foundation cracks with a cement compound and put a coat of waterproof paint on the walls. What should I do with the floors? The basement is dry but I don't want to take any chances with water seaping in from the floor. I plan to put carpet down and a little stone tile. What product should I use that will seal the floor and allow an adhesive to stick to the floor for the carpet and tile? Need the info? Thanks

Hi, I have a 104 year old farmhouse with a sometimes wet concrete basement. The centerbeam was supported by remodeling style steel loli columns set directly on the floor. They've all rotted out on the bottom and I need to replace them. Any recommendation on best way to replace them? I'm thinking of using solid concrete blocks leveled in a bed of mortar as pads to get the posts off the floor and replacing the rotted loli columns with either same type or with preasure treated 4x4 posts. Are wood posts and/or jacking type columns generally permitted by code? Am I okay with pads or do I need to cut into the floor and sink soni-tubes down (I believe my floor is at least 6" deep but would test before using the pads). Thanks for your advise! Randy
